dzVents OpenURL json to LUA how to read [Solved]

[snuiter]

Hi,
I am trying to get the weatherdetails from the KNMI API via

http://weerlive.nl/api/json-data-10min. ... ,5.1124231

The result from the openurl is in the following format

Spoiler: show

{ "liveweer": [{"plaats": "None", "temp": "0", "gtemp": "0", "samenv": "Gebruik een plaatsnaam of lat/lon-paar om het weerbericht op te vragen", "lv": "0", "windr": "0", "windms": "0", "winds": "0", "windk": "0", "windkmh": "0", "luchtd": "0", "ldmmhg": "0", "dauwp": "0", "zicht": "0", "verw": "0", "sup": "0", "sunder": "0", "image": "0", "d0weer": "0", "d0tmax": "0", "d0tmin": "0", "d0windk": "0", "d0windknp": "0", "d0windms": "0", "d0windkmh": "0", "d0windr": "0", "d0neerslag": "0", "d0zon": "0", "d1weer": "0", "d1tmax": "0", "d1tmin": "0", "d1windk": "0", "d1windknp": "0", "d1windms": "0", "d1windkmh": "0", "d1windr": "0", "d1neerslag": "0", "d1zon": "0", "d2weer": "0", "d2tmax": "0", "d2tmin": "0", "d2windk": "0", "d2windknp": "0", "d2windms": "0", "d2windkmh": "0", "d2windr": "0", "d2neerslag": "0", "d2zon": "0", "alarm": "0", "alarmtxt": "0"}]}

Now I am trying to retrieve the specific values from the output, I convert the JSON to a LUA table. Looking in the forum, internet and the dzVents wiki but not getting any value out of it.

Any ideas, this is the if loop in the script I am using? I have tried many formats but no luck, never any value in my output apart from the '-'

Appreciate your suggestions or hints in the right direction

Hi @waaren, need your help again!
Wunderground has changed its ratings and i want to get rid of it. I use the temperature for managing a livingboat like a told before.
I just made an account with http://weerlive.nl/api/json-data-10min. ... =Amsterdam and i can use it every 5 minutes for free!
Do you also have a dzvents version of the lua script ?

Hi, i added value "alarmtxt" and that wend well when there is an alarm.
But for now there isn't an alarm, and in that case the variable isnt even there in the list, instead of "alarmtxt": ""
Where do i put the check if the variable alarmtxt is available?

changing line

Code: Select all

if currentalarm  then currentalarm.updateText(weer.alarmtxt)    end

to

Code: Select all

if currentalarm  then currentalarm.updateText(weer.alarmtxt or "Geen alarm" )    end

should do it.

Hi,
remarkable that you can set n or statement in a place where a value is expected!
i was trying with:
if weer.alarmtxt ~= nil then
if currentalarm then currentalarm.updateText(weer.alarmtxt) end
end
but your solution is much better!

[waaren]

remarkable that you can set an or statement in a place where a value is expected!

That is the way the "or" syntax works in most languages. Only if the left part of an "or" statement evaluates to false / nil; the right part is evaluated. If the left part evaluaties to anything else; the right part is ignored.

i will try this :
if weer.alarmtxt ~= nil then
logWrite("Alarm : " .. weer.alarmtxt )
end

@update: this works! and now i also have a fine message when there is no warning, so thanks again!

you can do something similar there. Try

Code: Select all

logWrite("Alarm                : " .. (weer.alarmtxt or "Geen weeralarm actief") )

oh, does that or also works in that place, i will change it!

Hi all,

I started today with Domoticz so newbie question here.
I used the code from Waaren shown below, filled in my api key and saved it as .lua file in de Domoticz folder.
What I expected was an automatic update in my devices list with the weather information.
Nothing is happening. Do I need to add a dummy hardware device or something?
Still figuring out all the options of Domoticz.

Furthermore, the information I also wanted to get from the api is sun set and sun rise. How to include those?
Edit: I was looking for these parameters: https://weerlive.nl/delen.php
sun set and sun rise is added to the code using the parameters mentioned in the link.

Something like this ?

I started today with Domoticz so newbie question here.

When not yet familiar with dzVents please start with reading Get started Before implementing (~ 5 minutes). Special attention please for "In Domoticz go to Setup > Settings > Other and in the section EventSystem make sure the checkbox 'dzVents disabled' is not checked. Also make sure that in the Security section in the settings you allow 127.0.0.1 to not need a password. dzVents uses that port to send certain commands to Domoticz. Finally make sure you have set your current location in Setup > Settings > System > Location, otherwise there is no way to determine nighttime/daytime state.

I used the code from Waaren shown below, filled in my api key and saved it as .lua file in de Domoticz folder.
What I expected was an automatic update in my devices list with the weather information.
Nothing is happening. Do I need to add a dummy hardware device or something?

Yes you need to define dummy hardware with hardwareType: "Dummy (Does nothing, use for virtual switches only)" first and then create some virtual sensors as described in the script using the button on this hardware (on the hardware tab)

Thanks waaren for the link. I already set the settings you mentioned, but I made a mistake by placing the lua file in Domoticz\scripts instead of Domoticz\scripts\dzVents\scripts. I got it working now

@waaren : I managed in the past succesfully to work with a json in my dzvents script. With the next one, I don't get it to work, even after digging around on the internet for help. I assume I don't have a 100% understanding of json <> lua tables.

When I put this in the browser: http://user:[email protected]:8080/json ... :{booleans:[Player.HasAudio]},id:1}

than the response is: {"id":1,"jsonrpc":"2.0","result":{"Player.HasAudio":false}}


My code snippet is:

Code: Select all

if (device == testButton) then
   domoticz.openURL({
      url = 'http://user:[email protected]:8080/jsonrpc?request={jsonrpc:2.0,method:XBMC.GetInfoBooleans,params:{booleans:[Player.HasAudio]},id:1}',
      method = 'GET',
      callback = 'kodiIdleTimer'
   })
   elseif (device.isHTTPResponse and device.ok) then
      -- we know it is json but dzVents cannot detect this
      -- convert to Lua
      local json = domoticz.utils.fromJSON(device.data)
      -- json is now a Lua table
      
            print("The result true or false from the request is ".. json.result.Player.HasAudio)
elseif (device.isHTTPResponse and device.ok == false) then
  print("Response was not OK)
end

When I flip my testButton, the response in de domoticz log is:

attempt to index a nil value (field 'result')

I guess I have to do something with the Player.HasAudio, because it is on 1 level, but the 'dot' makes it look like the 'next level down'?

What do you see with this code snippet?

   domoticz.openURL({
      url = 'http://user:[email protected]:8080/jsonrpc?request={jsonrpc:2.0,method:XBMC.GetInfoBooleans,params:{booleans:[Player.HasAudio]},id:1}',
      method = 'GET',

   })
   elseif (device.isHTTPResponse and device.ok) then
      -- we know it is json but dzVents cannot detect this
      -- convert to Lua
      local json = domoticz.utils.fromJSON(device.data)
      -- json is now a Lua table
      
	 domoticz.log(device.data,domoticz.LOG_FORCE)
         domoticz.utils.dumpTable(json)
      
      print("The result true or false from the request is ".. json[1].result['Player.HasAudio'])
elseif (device.isHTTPResponse and device.ok == false) then
  print("Response was not OK)
end

The force log learned me stuff:

Code: Select all

2020-08-31 18:14:57.112 Status: dzVents: !Info: {"error":{"code":-32700,"message":"Parse error."},"id":null,"jsonrpc":"2.0"}
2020-08-31 18:14:57.112 Status: dzVents: > jsonrpc: 2.0

2020-08-31 18:14:57.112 Status: dzVents: > message: Parse error.

The result showed id:"null", while in the browser it is displayed as id: 1
This triggered me to put the " " back in the url: {"jsonrpc":"2.0","method":"XBMC.GetInfoBooleans","params":{"booleans":["Player.HasAudio"]},"id":1}

This improved the results in the log:

Code: Select all

Line 192 is:

Code: Select all

print("The result true or false from the request is ".. json[1].result['Player.HasAudio'])

UPDATE: well, well, I finally got it: I first 'tried' to change line 192 to json.result['Player.HasAudio']. This gave me the clue in the log:

Code: Select all

Error: (2.5.7) /home/pi/domoticz/scripts/dzVents/scripts/kodi3.lua:192: attempt to concatenate a boolean value (field 'Player.HasAudio

So i tried a different line of code on line 192 and finally with success:
if json.result['Player.HasAudio'] == false then print ("No audio is playing") end:

Code: Select all

2020-08-31 19:14:54.734 Status: dzVents: No audio is playing 
2020-08-31 19:14:54.734 Status: dzVents: !Info: {"id":1,"jsonrpc":"2.0","result":{"Player.HasAudio":false}}

2020-08-31 19:14:54.734 Status: dzVents: > Player.HasAudio: false

Thanks for pointing me in the right direction

Although I can now continue my script, I would like to know out of curiosity how I could still show the 'false' in a log line, instead of domoticz failing with 'attempt to concatenate a boolean value'

You can with

Code: Select all

print("The result true or false from the request is ".. tostring(json.result['Player.HasAudio']))

or

Code: Select all

domoticz.log("The result true or false from the request is ".. tostring(json.result['Player.HasAudio']), domoticz.LOG_FORCE)
