Hi,

Another idea :
Announce special event of the day, like first day of spring, labor day ... with a small definition.

I have found a perfect web page for french guys for that : http://www.dromadaire.com/calendrier
All that remains is to code a web scraper...

Did someone have something for that ?

Hi,

I had a working good morning announcement until I changed from 3.5mm jack to HDMI. Every file that I've tested (example.mp3 etc) plays fine but there is no sound when playing the speak.mp3 produced with this script. I'm puzzled :)

Tried omxplayer, mpg123 - no sound. Tried different audio formats - no sound. If I copy the speak.mp3 to my computer it plays fine. Any idea what could be the issue?

edit: I even tried now the izsynth script and the example provided in wiki. This also created an mp3 file that I can play on my laptop but not with RPi2, at least via HDMI.. :o

edit2: Correction to above that the player software (e.g. mpg123, omxplayer) does not give any error, just that there is no sound from the speakers :)

I have a working setup now, announing erverything on my Sonos Playbar. One problem however. When the temperature is 19.3 degrees for example it the scripts announces (in Dutch): It is 19 march degrees. When the temperature is 19.4 degrees it announces: It is 19 april degrees. It translates the decimal degrees to the name of the month for some reason.

Can you share your script please if you don't mind?

This script is fantastic - thank you! I have my Pi located behind a bookshelf with a computer speaker set attached to the audio-out port(2 speakers and the bass) as I also use it for streaming radio and making particular status announcements using izsynth therefore this script was the perfect addition.

Forecast.io is much more accurate where I am located in the Pacific Northwest of the US so I modified the script to pull from their API along with a few other changes such as allowing it to run most anytime of the day but still only once. I still have the remnants of WU but will be removing this once I return from vacation.

Code: Select all

indexCommand=1
commandArray = {}

function round(num, idp)
  local mult = 10^(idp or 0)
  return math.floor(num * mult + 0.5) / mult
end

local timeNow= os.date("*t")
currently= os.date
lastrun=otherdevices_lastupdate['PIRar9FrontRoom']
greet=(uservariables['Greeting']) -- morning, afternoon or evening

if devicechanged['PIRar9FrontRoom'] == 'On' and
   timeNow.hour >= 6 and -- earliest hour the script should run
   timeNow.hour <= 23 and -- latest hour the script should run
   string.sub(uservariables['goodMorning'],9,10) ~= os.date("%d") -- Only one time per day
then
   local sentence="Good "..greet.." to you. Today is "..(os.date("%A"))..", "..(os.date("%B")).." "..(os.date("%d"))..". "

   commandArray[indexCommand]={['Variable:goodMorning']=lastrun}  -- something to update "lastupdate"
   indexCommand=indexCommand+1
   
end
return commandArray
I added a rounding function as temperature, humidity and the like are often delivered to the hundredths which is not handled easily by the TTS output. My trash/recycling is handled by the building so I've no need for a reminder on this and have removed that particular code.

I travel on occasion and will typically have a friend house-sit to care for the plants, etc so I am working on an additional section that will 1) greet the house-sitter upon their first arrival (triggered by the front room/living room PIR) and remind them to water the plants, take in the mail, etc etc. I'll post the finalized version when completed.

Thanks again for the script! It's been turning heads and causing "oh my goodness!!" remarks ever since :)

Hello all
can someone write me what to do step by step to run this script? I don't know at all scripted and I would like to do when motion is detected in the living room to receive information such as weather. I write what I did until now.

1. i go to /home/pi/domoticz/scripts/lua/

2. I entered the command sudo nano script_device_switch.lua

3. I pasted there

indexCommand=1
commandArray = {}

local timeNow= os.date("*t")

if devicechanged['Sensor'] == 'On' and --Motion sensor Living Room ManualLaunchScript
timeNow.hour >6 and
string.sub(uservariables_lastupdate['goodMorning'], 9, 10) ~= os.date("%d") -- Only one time per day
then
local sentence="Hello"..tonumber(os.date("%d")) -- Good morning, today we are the ..

-- ############# TEMPERATURE & WEATHER FORECAST #################
sentence=sentence..". La température extérieure est de "..otherdevices_svalues['Sonde Solaire2'].." degré." -- outdoor temperature

local city = "Paris"
local wuAPIkey = "Apikey" -- Your Weather Underground API Key
local file=assert(io.popen('curl http://api.wunderground.com/api/'..wuAP ... ty..'.json'))
local raw = file:read('*all')
file:close()
local jsonForecast = json:decode(raw)
prevision=jsonForecast.forecast.txt_forecast.forecastday[1].fcttext_metric -- complete prevision
--prevision=jsonForecast.forecast.simpleforecast.forecastday[1].conditions -- small forecast

if tonumber(string.sub(otherdevices_svalues['Alerte Meteo'], 1, 1))==3 then -- Only for FRANCE. Weather Vigilance http://domogeek.entropialux.com/static/ ... tVigilance
sentence=sentence.."La météo est en vigilance orange :".. string.sub(otherdevices_svalues['Alerte Meteo'], 11)
elseif tonumber(string.sub(otherdevices_svalues['Alerte Meteo'], 1, 1))==4 then
sentence=sentence.."La météo est en vigilance rouge :".. string.sub(otherdevices_svalues['Alerte Meteo'], 11)
end
sentence=sentence.."Le temps de la journée sera "..prevision

-- ############# TRASH DAY #################
month=tonumber(os.date("%m"))
day=tonumber(os.date("%d"))

-- TRash day : Mardi vegetaux & ordure / jeudi recyclage & encombrant (pair) ou verre (impair) / samedi ordure

numOfWeek=tonumber(os.date("%V"))
numOfDay=os.date("%w")

if (numOfDay == '4') then -- thursday

if (numOfWeek % 2 ==0) then
sentence=sentence.."Les encombrants et la poubelle jaune sont rammassés ce matin." --pair
else
sentence=sentence.."Le verre et la poubelle jaune sont rammassés ce matin." --impair
end

elseif (numOfDay == '2') then -- Tuesday
if (month==3 and day>=15) or -- Vegetables trash between the 15 March and the 15 december
(month==12 and day<=15) or
(month>3 and month<12)
then
sentence=sentence.."Les vegetaux et "
end
sentence=sentence.."les poubelles sont ramassées ce matin."
elseif (numOfDay == '6') then -- Saturday
sentence=sentence.."les poubelles sont ramassées ce matin."
end

--print("talk:"..sentence)

os.execute ("/usr/bin/tts "..sentence.." &")

commandArray[indexCommand]={['Variable:goodMorning']="On"} -- something to update "lastupdate"
indexCommand=indexCommand+1

end
return commandArray


4.
next command sudo chmod 644 script_device_switch.lua

5. Check rights with ls -l

In the script i changed only the name of the sensor, and I put my key api

Now when the sensor detects motion console shows up this information:

2016-10-27 10:23:01.627 Error: EventSystem: in /home/pi/domoticz/scripts/lua/script_device_switch.lua:/home/pi/domoticz/scripts/lua/script_device_switch.lua:9: bad argument #1 to 'sub' (string expected, got nil)

Please help and forgive total amateur

Hi,

I regret to inform that this script is not "Ready to use". You will need some Lua skills to achieve.

Your error seems to be about the goodMorning uservariable. Did you create it ?

Hi. I try to make work the script but I get this error :
Error: EventSystem: /home/pi/domoticz/scripts/lua/script_time_presence.lua:35: attempt to call a nil value


and the line 35 is this one :
json = (loadfile "/home/pi/domoticz/scripts/lua/JSON.lua")() --mettre le script json.lua dans le chemin indiqué
local city = "Paris"
local wuAPIkey = "****************" -- Your Weather Underground API Key

local raw = file:read('*all')
file:close()
local jsonForecast = json:decode(raw)

--prevision=jsonForecast.forecast.simpleforecast.forecastday[1].conditions -- small forecast
sentenceprev="Le temps de la journée sera "..prevision
os.execute ("/usr/bin/tts " ..sentenceprev.."&" )




Do I have the good JSON.lua?

--
-- Simple JSON encoding and decoding in pure Lua.
-- JSON definition: http://www.json.org/
--
--
--   JSON = assert(loadfile "JSON.lua")() -- one-time load of the routines
--
--   local lua_value = JSON:decode(raw_json_text)
--
--   local raw_json_text    = JSON:encode(lua_table_or_value)

--
--
--
-- DECODING (from a JSON string to a Lua table)
--
--
--   JSON = assert(loadfile "JSON.lua")() -- one-time load of the routines
--
--   local lua_value = JSON:decode(raw_json_text)
--
--   If the JSON text is for an object or an array, e.g.
--     { "what": "books", "count": 3 }
--   or
--     [ "Larry", "Curly", "Moe" ]
--
--   the result is a Lua table, e.g.
--     { what = "books", count = 3 }
--   or
--     { "Larry", "Curly", "Moe" }
--
--
--   The encode and decode routines accept an optional second argument,
--   "etc", which is not used during encoding or decoding, but upon error
--   is passed along to error handlers. It can be of any type (including nil).
--
--
--
-- ERROR HANDLING
--
--   With most errors during decoding, this code calls
--
--      JSON:onDecodeError(message, text, location, etc)
--
--   with a message about the error, and if known, the JSON text being
--   parsed and the byte count where the problem was discovered. You can
--   replace the default JSON:onDecodeError() with your own function.
--
--   The default onDecodeError() merely augments the message with data
--   about the text and the location if known (and if a second 'etc'
--   argument had been provided to decode(), its value is tacked onto the
--   message as well), and then calls JSON.assert(), which itself defaults
--   to Lua's built-in assert(), and can also be overridden.
--
--   For example, in an Adobe Lightroom plugin, you might use something like
--
--          function JSON:onDecodeError(message, text, location, etc)
--             LrErrors.throwUserError("Internal Error: invalid JSON data")
--          end
--
--   or even just
--
--          function JSON.assert(message)
--             LrErrors.throwUserError("Internal Error: " .. message)
--          end
--
--   If JSON:decode() is passed a nil, this is called instead:
--
--      JSON:onDecodeOfNilError(message, nil, nil, etc)
--
--   and if JSON:decode() is passed HTML instead of JSON, this is called:
--
--      JSON:onDecodeOfHTMLError(message, text, nil, etc)
--
--   The use of the fourth 'etc' argument allows stronger coordination
--   between decoding and error reporting, especially when you provide your
--   own error-handling routines. Continuing with the the Adobe Lightroom
--   plugin example:
--
--          function JSON:onDecodeError(message, text, location, etc)
--             local note = "Internal Error: invalid JSON data"
--             if type(etc) = 'table' and etc.photo then
--                note = note .. " while processing for " .. etc.photo:getFormattedMetadata('fileName')
--             end
--             LrErrors.throwUserError(note)
--          end
--
--            :
--            :
--
--          for i, photo in ipairs(photosToProcess) do
--               :             
--               :             
--               local data = JSON:decode(someJsonText, { photo = photo })
--               :             
--               :             
--          end
--
--
--
--
--
-- DECODING AND STRICT TYPES
--
--   Because both JSON objects and JSON arrays are converted to Lua tables,
--   it's not normally possible to tell which original JSON type a
--   particular Lua table was derived from, or guarantee decode-encode
--   round-trip equivalency.
--
--   However, if you enable strictTypes, e.g.
--
--      JSON = assert(loadfile "JSON.lua")() --load the routines
--      JSON.strictTypes = true
--
--   then the Lua table resulting from the decoding of a JSON object or
--   JSON array is marked via Lua metatable, so that when re-encoded with
--   JSON:encode() it ends up as the appropriate JSON type.
--
--   (This is not the default because other routines may not work well with
--   tables that have a metatable set, for example, Lightroom API calls.)
--
--
-- ENCODING (from a lua table to a JSON string)
--
--   JSON = assert(loadfile "JSON.lua")() -- one-time load of the routines
--
--   local raw_json_text    = JSON:encode(lua_table_or_value)
--   local pretty_json_text = JSON:encode_pretty(lua_table_or_value) -- "pretty printed" version for human readability
--   local custom_pretty    = JSON:encode(lua_table_or_value, etc, { pretty = true, indent = "|  ", align_keys = false })
--
--   On error during encoding, this code calls:
--
--     JSON:onEncodeError(message, etc)
--
--   which you can override in your local JSON object.
--
--   The 'etc' in the error call is the second argument to encode()
--   and encode_pretty(), or nil if it wasn't provided.
--
--
-- ENCODING OPTIONS
--
--   An optional third argument, a table of options, can be provided to encode().
--
--       encode_options =  {
--           -- options for making "pretty" human-readable JSON (see "PRETTY-PRINTING" below)
--           pretty         = true,
--           indent         = "   ",
--           align_keys     = false,
--  
--           -- other output-related options
--           null           = "\0",   -- see "ENCODING JSON NULL VALUES" below
--           stringsAreUtf8 = false,  -- see "HANDLING UNICODE LINE AND PARAGRAPH SEPARATORS FOR JAVA" below
--       }
--  
--       json_string = JSON:encode(mytable, etc, encode_options)
--
--
--
-- For reference, the defaults are:
--
--           pretty         = false
--           null           = nil,
--           stringsAreUtf8 = false,
--
--
--
-- PRETTY-PRINTING
--
--   Enabling the 'pretty' encode option helps generate human-readable JSON.
--
--     pretty = JSON:encode(val, etc, {
--                                       pretty = true,
--                                       indent = "   ",
--                                       align_keys = false,
--                                     })
--
--   encode_pretty() is also provided: it's identical to encode() except
--   that encode_pretty() provides a default options table if none given in the call:
--
--       { pretty = true, align_keys = false, indent = "  " }
--
--   For example, if
--
--      JSON:encode(data)
--
--   produces:
--
--      {"city":"Kyoto","climate":{"avg_temp":16,"humidity":"high","snowfall":"minimal"},"country":"Japan","wards":11}

--
--
--  HANDLING UNICODE LINE AND PARAGRAPH SEPARATORS FOR JAVA
--
--    If the 'stringsAreUtf8' encode option is set to true, consider Lua strings not as a sequence of bytes,
--    but as a sequence of UTF-8 characters.
--
--    Currently, the only practical effect of setting this option is that Unicode LINE and PARAGRAPH
--    separators, if found in a string, are encoded with a JSON escape instead of being dumped as is.
--    The JSON is valid either way, but encoding this way, apparently, allows the resulting JSON
--    to also be valid Java.
--
--  AMBIGUOUS SITUATIONS DURING THE ENCODING
--
--   During the encode, if a Lua table being encoded contains both string
--   and numeric keys, it fits neither JSON's idea of an object, nor its
--   idea of an array. To get around this, when any string key exists (or
--   when non-positive numeric keys exist), numeric keys are converted to
--   strings.
--
--   For example, 
--     JSON:encode({ "one", "two", "three", SOMESTRING = "some string" }))
--   produces the JSON object
--     {"1":"one","2":"two","3":"three","SOMESTRING":"some string"}
--
--   To prohibit this conversion and instead make it an error condition, set
--      JSON.noKeyConversion = true
--
--
-- ENCODING JSON NULL VALUES
--
--   Lua tables completely omit keys whose value is nil, so without special handling there's
--   no way to get a field in a JSON object with a null value.  For example
--      JSON:encode({ username = "admin", password = nil })
--   produces
--      {"username":"admin"}
--
--   In order to actually produce
--      {"username":"admin", "password":null}
--   one can include a string value for a "null" field in the options table passed to encode().... 
--   any Lua table entry with that value becomes null in the JSON output:
--      JSON:encode({ username = "admin", password = "xyzzy" }, nil, { null = "xyzzy" })
--   produces
--      {"username":"admin", "password":null}
--
--   Just be sure to use a string that is otherwise unlikely to appear in your data.
--   The string "\0" (a string with one null byte) may well be appropriate for many applications.
--
--   The "null" options also applies to Lua tables that become JSON arrays.
--      JSON:encode({ "one", "two", nil, nil })
--   produces
--      ["one","two"]
--   while
--      NULL = "\0"
--      JSON:encode({ "one", "two", NULL, NULL}, nil, { null = NULL })
--   produces
--      ["one","two",null,null]
--
--
--
--
-- HANDLING LARGE AND/OR PRECISE NUMBERS
--
--
--   Without special handling, numbers in JSON can lose precision in Lua.
--   For example:
--   
--      T = JSON:decode('{  "small":12345, "big":12345678901234567890123456789, "precise":9876.67890123456789012345  }')
--
--      print("small:   ",  type(T.small),    T.small)
--      print("big:     ",  type(T.big),      T.big)
--      print("precise: ",  type(T.precise),  T.precise)
--   
--   produces
--   
--      small:          number  12345
--      big:            number  1.2345678901235e+28
--      precise:        number  9876.6789012346
--
--   Precision is lost with both 'big' and 'precise'.
--
--   This package offers ways to try to handle this better (for some definitions of "better")...
--
--   The most precise method is by setting the global:
--   
--      JSON.decodeNumbersAsObjects = true
--   
--   When this is set, numeric JSON data is encoded into Lua in a form that preserves the exact
--   JSON numeric presentation when re-encoded back out to JSON, or accessed in Lua as a string.
--
--   (This is done by encoding the numeric data with a Lua table/metatable that returns
--   the possibly-imprecise numeric form when accessed numerically, but the original precise
--   representation when accessed as a string. You can also explicitly access
--   via JSON:forceString() and JSON:forceNumber())
--
--   Consider the example above, with this option turned on:
--
--      JSON.decodeNumbersAsObjects = true
--      
--      T = JSON:decode('{  "small":12345, "big":12345678901234567890123456789, "precise":9876.67890123456789012345  }')
--
--      print("small:   ",  type(T.small),    T.small)
--      print("big:     ",  type(T.big),      T.big)
--      print("precise: ",  type(T.precise),  T.precise)
--   
--   This now produces:
--   
--      small:          table   12345
--      big:            table   12345678901234567890123456789
--      precise:        table   9876.67890123456789012345
--   
--   However, within Lua you can still use the values (e.g. T.precise in the example above) in numeric
--   contexts. In such cases you'll get the possibly-imprecise numeric version, but in string contexts
--   and when the data finds its way to this package's encode() function, the original full-precision
--   representation is used.
--
--   Even without using the JSON.decodeNumbersAsObjects option, you can encode numbers
--   in your Lua table that retain high precision upon encoding to JSON, by using the JSON:asNumber()
--   function:
--
--      T = {
--         imprecise = 123456789123456789.123456789123456789,
--         precise   = JSON:asNumber("123456789123456789.123456789123456789")
--      }
--
--      print(JSON:encode_pretty(T))
--
--   This produces:
--
--      { 
--         "precise": 123456789123456789.123456789123456789,
--         "imprecise": 1.2345678912346e+17
--      }
--
--
--
--   A different way to handle big/precise JSON numbers is to have decode() merely return
--   the exact string representation of the number instead of the number itself.
--   This approach might be useful when the numbers are merely some kind of opaque
--   object identifier and you want to work with them in Lua as strings anyway.
--   
--   This approach is enabled by setting
--
--      JSON.decodeIntegerStringificationLength = 10
--
--   The value is the number of digits (of the integer part of the number) at which to stringify numbers.
--
--   Consider our previous example with this option set to 10:
--
--      JSON.decodeIntegerStringificationLength = 10
--      
--      T = JSON:decode('{  "small":12345, "big":12345678901234567890123456789, "precise":9876.67890123456789012345  }')
--
--      print("small:   ",  type(T.small),    T.small)
--      print("big:     ",  type(T.big),      T.big)
--      print("precise: ",  type(T.precise),  T.precise)
--
--   This produces:
--
--      small:          number  12345
--      big:            string  12345678901234567890123456789
--      precise:        number  9876.6789012346
--
--   The long integer of the 'big' field is at least JSON.decodeIntegerStringificationLength digits
--   in length, so it's converted not to a Lua integer but to a Lua string. Using a value of 0 or 1 ensures
--   that all JSON numeric data becomes strings in Lua.
--
--   Note that unlike
--      JSON.decodeNumbersAsObjects = true
--   this stringification is simple and unintelligent: the JSON number simply becomes a Lua string, and that's the end of it.
--   If the string is then converted back to JSON, it's still a string. After running the code above, adding
--      print(JSON:encode(T))
--   produces
--      {"big":"12345678901234567890123456789","precise":9876.6789012346,"small":12345}
--   which is unlikely to be desired.
--
--   There's a comparable option for the length of the decimal part of a number:
--
--      JSON.decodeDecimalStringificationLength
--
--   This can be used alone or in conjunction with
--
--      JSON.decodeIntegerStringificationLength
--
--   to trip stringification on precise numbers with at least JSON.decodeIntegerStringificationLength digits after
--   the decimal point.
--
--   This example:
--
--      JSON.decodeIntegerStringificationLength = 10
--      JSON.decodeDecimalStringificationLength =  5
--
--      T = JSON:decode('{  "small":12345, "big":12345678901234567890123456789, "precise":9876.67890123456789012345  }')
--      
--      print("small:   ",  type(T.small),    T.small)
--      print("big:     ",  type(T.big),      T.big)
--      print("precise: ",  type(T.precise),  T.precise)
--
--  produces:
--
--      small:          number  12345
--      big:            string  12345678901234567890123456789
--      precise:        string  9876.67890123456789012345

--   20160730.18   Added JSON:forceString() and JSON:forceNumber()
--
--   20160728.17   Added concatenation to the metatable for JSON:asNumber()
--
--   20160709.16   Could crash if not passed an options table (thanks jarno heikkinen <[email protected]>).
--
--                 Made JSON:asNumber() a bit more resilient to being passed the results of itself.
--
--   20160526.15   Added the ability to easily encode null values in JSON, via the new "null" encoding option.
--                 (Thanks to Adam B for bringing up the issue.)
--
--                 Added some support for very large numbers and precise floats via
--                    JSON.decodeNumbersAsObjects
--                    JSON.decodeIntegerStringificationLength
--                    JSON.decodeDecimalStringificationLength
--
--                 Added the "stringsAreUtf8" encoding option. (Hat tip to http://lua-users.org/wiki/JsonModules )
--
--   20141223.14   The encode_pretty() routine produced fine results for small datasets, but isn't really
--                 appropriate for anything large, so with help from Alex Aulbach I've made the encode routines
--                 more flexible, and changed the default encode_pretty() to be more generally useful.
--
--                 Added a third 'options' argument to the encode() and encode_pretty() routines, to control
--                 how the encoding takes place.
--
--                 Updated docs to add assert() call to the loadfile() line, just as good practice so that
--                 if there is a problem loading JSON.lua, the appropriate error message will percolate up.
--
--   20140920.13   Put back (in a way that doesn't cause warnings about unused variables) the author string,
--                 so that the source of the package, and its version number, are visible in compiled copies.
--
--   20140911.12   Minor lua cleanup.
--                 Fixed internal reference to 'JSON.noKeyConversion' to reference 'self' instead of 'JSON'.
--                 (Thanks to SmugMug's David Parry for these.)
--
--   20140418.11   JSON nulls embedded within an array were being ignored, such that
--                     ["1",null,null,null,null,null,"seven"],
--                 would return
--                     {1,"seven"}
--                 It's now fixed to properly return
--                     {1, nil, nil, nil, nil, nil, "seven"}
--                 Thanks to "haddock" for catching the error.
--
--   20140116.10   The user's JSON.assert() wasn't always being used. Thanks to "blue" for the heads up.
--
--   20131118.9    Update for Lua 5.3... it seems that tostring(2/1) produces "2.0" instead of "2",
--                 and this caused some problems.
--
--   20131031.8    Unified the code for encode() and encode_pretty(); they had been stupidly separate,
--                 and had of course diverged (encode_pretty didn't get the fixes that encode got, so
--                 sometimes produced incorrect results; thanks to Mattie for the heads up).
--
--                 Handle encoding tables with non-positive numeric keys (unlikely, but possible).
--
--                 If a table has both numeric and string keys, or its numeric keys are inappropriate
--                 (such as being non-positive or infinite), the numeric keys are turned into
--                 string keys appropriate for a JSON object. So, as before,
--                         JSON:encode({ "one", "two", "three" })
--                 produces the array
--                         ["one","two","three"]
--                 but now something with mixed key types like
--                         JSON:encode({ "one", "two", "three", SOMESTRING = "some string" }))
--                 instead of throwing an error produces an object:
--                         {"1":"one","2":"two","3":"three","SOMESTRING":"some string"}
--
--                 To maintain the prior throw-an-error semantics, set
--                      JSON.noKeyConversion = true
--                 
--   20131004.7    Release under a Creative Commons CC-BY license, which I should have done from day one, sorry.
--
--   20130120.6    Comment update: added a link to the specific page on my blog where this code can
--                 be found, so that folks who come across the code outside of my blog can find updates
--                 more easily.
--
--   20111207.5    Added support for the 'etc' arguments, for better error reporting.
--
--   20110731.4    More feedback from David Kolf on how to make the tests for Nan/Infinity system independent.
--
--   20110730.3    Incorporated feedback from David Kolf at http://lua-users.org/wiki/JsonModules:
--
--                   * When encoding lua for JSON, Sparse numeric arrays are now handled by
--                     spitting out full arrays, such that
--                        JSON:encode({"one", "two", [10] = "ten"})
--                     returns
--                        ["one","two",null,null,null,null,null,null,null,"ten"]
--
--                     In 20100810.2 and earlier, only up to the first non-null value would have been retained.
--
--                   * When encoding lua for JSON, numeric value NaN gets spit out as null, and infinity as "1+e9999".
--                     Version 20100810.2 and earlier created invalid JSON in both cases.
--
--                   * Unicode surrogate pairs are now detected when decoding JSON.
--
--   20100810.2    added some checking to ensure that an invalid Unicode character couldn't leak in to the UTF-8 encoding
--
--   20100731.1    initial public release
--

Do I have to give special rights to this file?
Any idea?

Hi,

You have the right json.lua file.

Did you named your script : "script_time_presence.lua" ?!? Our vocal script shall be a device script.
Are you sure that you aren't mixing everything ?

Hi dijon :-)

This script is not "ready to use". If you don't understand and don't have the skill to complete the script , just delete the part line 26 to 30.

If you want to persist for the "weather vigilance", then you have to implement this another script (only for France):

@ jmieglise : Hi. Thank you for your answer.
Yes your right, I've named my script : "script_time_presence.lua" and, now, I'm sure that I have mixed everything.

Well, I'm trying to have Temperature and wrather forecast when my ip address phone is detected. Here is my script:

Code: Select all

function os.capture(cmd)
  local f = assert(io.popen(cmd, 'r'))
  local s = assert(f:read('*a'))
  f:close()

local TempFigeac = otherdevices_svalues["TempHumF"]:match("([^;]+)")
local TempSalon = otherdevices_svalues["Salon"]:match("([^;]+)")
local sentence = "Nous sommes le "..ojourdui
local sentence2 = "il est "..os.date("%H").." heure "..os.date("%M")..". Dehors il fait"..TempOuest.." degré,"..TempSalon.." dans le salon. Et à F "..TempFigeac
--Cette fonction calcule la différence de temps (en secondes) entre maintenant
--et la date passée en paramètre.
function timedifference (s)
  year = string.sub(s, 1, 4)
  month = string.sub(s, 6, 7)
  day = string.sub(s, 9, 10)
  hour = string.sub(s, 12, 13)
  minutes = string.sub(s, 15, 16)
  seconds = string.sub(s, 18, 19)
  t1 = os.time()
  t2 = os.time{year=year, month=month, day=day, hour=hour, min=minutes, sec=seconds}
  difference = os.difftime (t1, t2)
  return difference
end
print(ojourdui)

return commandArray



How cann I use the json.lua file and get weather forecast this way?

Hello jmleglise !

I am sure that I am already using one of your script as your username is not unknown for me ! ;)

You're right I don't have the skills and I am learning in trying to adapt the script I find to my needs and to windows. After reading another time the script, I understood the mistake for the meteo alert... Silly me !

I am now facing an issue that I can't understand...

I saved the script as a device script into the Domoticz script editor and I am not getting error again but I am getting... nothing !
Just a question regarind the goodMorning user value. I set it as a "entier" value and set it to 3 for the beginning

Am I right ?

Code: Select all

indexCommand=1
commandArray = {}

local timeNow= os.date("*t")

if devicechanged['Libre2'] == 'On' and --Motion sensor Living Room ManualLaunchScript
timeNow.hour >14 and
string.sub(uservariables_lastupdate['goodMorning'], 9, 10) ~= os.date("%d") -- Only one time per day
then
local sentence="Hello"..tonumber(os.date("%d")) -- Good morning, today we are the ..
local curl = 'C:\\curl\\bin\\curl.exe '

-- #############  TEMPERATURE & WEATHER FORECAST  #################   
   sentence=sentence..". La température extérieure est de "..otherdevices_svalues['Température extérieure'].." degré." -- outdoor temperature

   local jsonForecast = json:decode(raw)   
   prevision=jsonForecast.forecast.txt_forecast.forecastday[1].fcttext_metric  -- complete prevision
   --prevision=jsonForecast.forecast.simpleforecast.forecastday[1].conditions  -- small forecast

   if tonumber(string.sub(otherdevices_svalues['Risque de givre'], 1, 1))==3 then -- Only for FRANCE. Weather Vigilance  http://domogeek.entropialux.com/static/doc/index.html#api-Domogeek-GetVigilance
      sentence=sentence.."il y a peut etre du givre".. string.sub(otherdevices_svalues['Alerte Meteo'], 11)
   elseif tonumber(string.sub(otherdevices_svalues['Risque de givre'], 1, 1))==4 then
      sentence=sentence.."Attention il y a du givre".. string.sub(otherdevices_svalues['Alerte Meteo'], 11) 
   end
   sentence=sentence.."Le temps de la journée sera "..prevision
I would be thankful if somebody explain me why I am getting this issue :roll:

Well, I manage to get something but the SARAH windows app I used with http request for TTS does not like the "." as well as the space and the ";" and so...


@jmleglise : do you know if izsynth works under windows ? I am searching a way to bypass the space and whatever restriction for SARAH

Or a way to encode space and dots... with JSON ?

Hi. I try to make work this script (named script_device_forecast.lua, in ~/domoticz/scripts/lua, where on can find the file json.lua) :

Code: Select all


commandArray = {}
local timeNow= os.date("*t")
if devicechanged['DIO54700_1'] == 'On'
then
   local sentence="Bonjour, nous sommes aujourd'hui le "..tonumber(os.date("%d"))  -- Good morning, today we are the ..
-- #############  TEMPERATURE & WEATHER FORECAST  #################
   sentence=sentence..". La température extérieure est de "..otherdevices_svalues['Temp Ouest'].." degré." -- outdoor temperature
   json = (loadfile "/home/pi/domoticz/scripts/lua/json.lua")()
   local city = "Paris"
   local wuAPIkey = "12aa25aa22aa55aa55aa" -- Your Weather Underground API Key
   local file=assert(io.popen('curl http://api.wunderground.com/api/'..wuAPIkey..'/forecast/lang:FR/q/France/'..city..'.json'))
   local raw = file:read('*all')
   file:close()
   local jsonForecast = json:decode(raw)
   prevision=jsonForecast.forecast.txt_forecast.forecastday[1].fcttext_metric  -- complete prevision
   --prevision=jsonForecast.forecast.simpleforecast.forecastday[1].conditions  -- small forecast

   if tonumber(string.sub(otherdevices_svalues['Alerte Meteo'], 1, 1))==3 then -- Only for FRANCE. Weather Vigilance  http://domogeek.entropialux.com/static/doc/index.html#api-Domogeek-GetVigilance
      sentence=sentence.."La météo est en vigilance orange :".. string.sub(otherdevices_svalues['Alerte Meteo'], 11)
   elseif tonumber(string.sub(otherdevices_svalues['Alerte Meteo'], 1, 1))==4 then
      sentence=sentence.."La météo est en vigilance rouge :".. string.sub(otherdevices_svalues['Alerte Meteo'], 11)
   end
   sentence=sentence.."Le temps de la journée sera "..prevision
    print("talk:"..sentence)
   os.execute ("/usr/bin/tts "..sentence.." &")
end
return commandArray



When I push on the DIO54700_1 device I get :

2016-12-23 17:14:12.150 Error: EventSystem: /home/pi/domoticz/scripts/lua/script_device_forecast.lua:8: attempt to call a nil value

do you know where I've made an error?
