LUA: Summer / Winter from timeofday or other...

[jcjames13009]

Hi,

Do we have possibility to retreive season (Winter, Summer, etc...) using Lua script.

something like timeofday['Nighttime'] but for season.

Couldn't find something in the forum and net

Thansk in advance

Seasons are fixed, 4 dates every year, why not hard code that?

[ThinkPad]

Hardcoding it is also done by people using other home automation systems: http://board.homeseer.com/showthread.php?t=155133

[jcjames13009]

That's what I was thinking about. But wanted to know before if there were an easier solution.
Thanks
JC

[jannl]

Normally hardcoding is the easy way.

[jcjames13009]

Hi

That's what I did:

Solution 1: Use dummy switches one for each season

Capture Saisons 1.PNG (58.84 KiB) Viewed 6847 times

with the following lua script that set each switch to "ON" or "OFF" depending on season change date

Code: Select all

-- script_device_SaisonSW.lua
-- Ce script permet de gérer des switches virtuel pour chaque saison:
--    Printemps / Eté / Automne / Hiver
-- Le changement d'état se fait à date fixe: 
-- 	  21/03 pour le printemps 
-- 	  21/06 pour l'été 
-- 	  21/09 pour l'automne 
-- 	  21/12 pour l'hiver
-- Le script est lancé une fois par jour lors du basculement du switch virtuel 'Jour' synchronisé sur l'heure de levé et couché du soleil

local SWPrintemps = 'Printemps'	-- Switch virtuel printemps
local SWEte = 'Eté'				-- Switch virtuel été
local SWAutomne = 'Automne'		-- Switch virtuel automne
local SWHiver = 'Hiver'			-- Switch virtuel hiver

commandArray = {}

-- Récuperation de l'heure
time = os.time()
mois = tonumber(os.date('%m', time))
jours = tonumber(os.date('%d', time))

if devicechanged['Jour'] == 'On' then
	if (mois == 03 and jours >= 21 and otherdevices[SWPrintemps] == 'Off') then
		-- print(' > C\'est le printemps')	-- Pour debug
		commandArray[SWPrintemps]='On'		-- C'est le printemps
		commandArray[SWEte]='Off'
		commandArray[SWAutomne]='Off'
		commandArray[SWHiver]='Off'
	end
	if (mois == 06 and jours >= 21 and otherdevices[SWEte] == 'Off') then
		-- print(' > C\'est l\'été')		-- Pour debug
		commandArray[SWPrintemps]='Off'
		commandArray[SWEte]='On'			-- C'est l'été
		commandArray[SWAutomne]='Off'
		commandArray[SWHiver]='Off'
	end
	if (mois == 09 and jours >= 21 and otherdevices[SWAutomne] == 'Off') then
		-- print(' > C\'est l\'automne')	-- Pour debug
		commandArray[SWPrintemps]='Off'
		commandArray[SWEte]='Off'
		commandArray[SWAutomne]='On'		-- C'est l'automne
		commandArray[SWHiver]='Off'
	end	
	if (mois == 12 and jours >= 21 and otherdevices[SWHiver] == 'Off') then
		-- print(' > C\'est l\'hiver')		-- Pour debug
		commandArray[SWPrintemps]='Off'
		commandArray[SWEte]='Off'
		commandArray[SWAutomne]='Off'
		commandArray[SWHiver]='On'			-- C'est l'hiver
	end	
end

return commandArray

Solution 2: Use user variable

Capture Saisons 2.PNG (4.64 KiB) Viewed 6847 times

with the following lua script that change the value of the variable at season change date

Code: Select all

-- script_device_SaisonVU.lua
-- Ce script permet de gérer la valeur d'une variable utilisateur en fonction de la saision :
--    Printemps / Eté / Automne / Hiver
-- Le changement d'état se fait à date fixe : 
-- 	  21/03 pour le printemps 
-- 	  21/06 pour l'été 
-- 	  21/09 pour l'automne 
-- 	  21/12 pour l'hiver
-- Le script est lancé une fois par jour lors du basculement du switch virtuel 'Jour' synchronisé sur l'heure de levé et couché du soleil

commandArray = {}

-- Récuperation de l'heure
time = os.time()
mois = tonumber(os.date('%m', time))
jours = tonumber(os.date('%d', time))

if devicechanged['Jour'] == 'On' then
	if mois == 03 and jours >= 21 then 
		-- print(' > C\'est le printemps')				-- Pour debug
		commandArray['Variable:Saison'] = 'Printemps'	-- C'est le printemps
	end
	if mois == 06 and jours >= 21 then 
		-- print(' > C\'est l\'été')					-- Pour debug
		commandArray['Variable:Saison'] = 'Eté'			-- C'est l'été
	end
	if mois == 09 and jours >= 21 then 
		-- print(' > C\'est l\'automne')				-- Pour debug
		commandArray['Variable:Saison'] = 'Automne'		-- C'est l'automne
	end
	if mois == 12 and jours >= 21 then 
		-- print(' > C\'est l\'hiver')					-- Pour debug
		commandArray['Variable:Saison'] = 'Hiver'		-- C'est l'hiver
	end
end

return commandArray

Maybe it can help someone.

Thanks for sharing. I don't understand French very well, but i can 'read' how the script works luckily
Where do you use this for?

Can user variable be used in Blockly?
IF Var_Season = Summer
DO SET light1 = On

?

Otherwise if it is just for showing text, you could also use a text sensor and update it with this:

Code: Select all

commandArray['OpenURL'] = "http://127.0.0.1:8080/json.htm?type=command&param=udevice&idx=IDX&nvalue=0&svalue=TEXT"

Text sensor can be created by Setup > Hardware > Dummy hardware. Then at the dummy hardware click 'Create device', type 'text'

[jcjames13009]

Hi,

Thanks for the tip about Text Sensor. I didn't knew about taht

Cannot answer you for user variables in Blocky. I never tested it before.

And sorry for the text in french. Google works fine for transaltaion (just tested it). But I'll try to do an english version

I'll use this feature to manage humidity extraction (VMC in French). To let the extractor running at max speed during the night in summer when outside temp is lower that inside one to cool down (a bit) the house. Stop extraction in winter during the night to don't waste eating.

I plan to use it also to manage pool water pump and cleaning robot time slots depending on season.

Will post corresponding scrips as well

JC

[ThinkPad]

But how do you control the extractor? By the virtual switches method you described?
IF Fan = Off AND Summer = On
DO SET Fan = Off

Like that?

[Derik]

Someone has this working???
Found some scripts [ thanks to the maker?? ] only cannot get this working..?

Code: Select all

-- script_device_season.lua
-- This script allows you to manage the value of a user variable depending on this season:
-- Spring Summer Fall Winter
-- The change of state is a fixed date:

-- Zomer: 1 juni t/m 31 augustus
-- Herfst: 1 september t/m 30 november
-- Winter: 1 december t/m 28 februari
-- The script is run once a day when the virtual switch 'Day' gets flipped (every sunset & sunrise)
commandArray = {}

time = os.time()
month = tonumber(os.date('%m', time))
day = tonumber(os.date('%d', time))

if devicechanged['IsDonker (virt)'] == 'On' then
   if month == 03 and day >= 21 then 
      print('Het seizoen is veranderd, het is nu lente')
      commandArray['Variable:Seizoen'] = 'Lente'

   end

   end
end

return commandArray

Please help

Or perhaps some one have 4 dummy switches that are flipping by the seasons...

[jvdz]

Which part isn't working for you?
You do have a virtual device called "IsDonker (virt)" which is set to On each day?
You realize that the tests for month&day will be valid multiple days on and after the 21st of the specified month?

The hole part is not working because i do not understand this script...
isdonker dos not say a thing for me.

What i am simple looking for is ...
4 switches that switching on or of whe a season is active

[jvdz]

Understood, a learning experience for you.
So what are your exact switchnames to use for the 4 seasons?

Jos

[Derik]

All dummys:
Voorjaar : IDX:4194
Zomer : IDX: 4195
Herfst : IDX: 4196
Winter: IDX: 4197

[jvdz]

Something like this should be close.
Save the below code as script_time_season.lua. It will run each minute and will only change the Switches to the appropriate setting when something changes.
Let me know when you have questions.

Code: Select all

-- script_time_season.lua
-- The change of state is a fixed date:
-- Lente: 21 maart t/m 20 juni
-- Zomer: 21 juni t/m 20 september
-- Herfst: 21 september t/m 20 december
-- Winter: 21 december t/m 20 maart
-- The script is run once a time.day when the virtual switch 'time.day' gets flipped (every sunset & sunrise)
commandArray = {}

time = os.date("*t")
Seizoen = '????'
-- check once a minute for the season to change
if (time.month == 12 and time.day >= 21)
or (time.month == 1)
or (time.month == 2)
or (time.month == 3 and time.day < 21) then
	Seizoen = 'Winter'
elseif (time.month == 3)
or (time.month == 4)
or (time.month == 5)
or (time.month == 6 and time.day < 21) then
	Seizoen = 'Voorjaar'
elseif (time.month == 6)
or (time.month == 7)
or (time.month == 8)
or (time.month == 9 and time.day < 21) then
	Seizoen = 'Zomer'
elseif (time.month == 9)
or (time.month == 10)
or (time.month == 11)
or (time.month == 12 and time.day < 21) then
	Seizoen = 'Herfst'
else
	print('Something wrong in the season logic :)')
end
if Seizoen ~= '????' and otherdevices[Seizoen] ~= 'On' then
	-- reset all switches to Off
	print('Het seizoen is veranderd, het is nu '..Seizoen)
	commandArray['Winter'] = 'Off'
	commandArray['Voorjaar'] = 'Off'
	commandArray['Zomer'] = 'Off'
	commandArray['Herfst'] = 'Off'
	-- reset current season to On
	commandArray[Seizoen] = 'On'
end

return commandArray

Really great work!!!!
Thanks!!!

One question. why do i need no IDX?

A option to place your code in the wiki...

[deennoo]

Hello.

There is a free API d'or this.

This not a LUA script but works great, you need to create a dummy text device.

We create it on Easydomoticz.com a Domoticz french forum.

File: saison.sh
#!/bin/bash
saison=$(curl -s "http://domogeek.entropialux.com/season")
echo $saison

if [ $saison = "autumn" ];then
saisonfr="Automne"

elif [ $saison = "winter" ];then
saisonfr="Hiver"
elif [ $saison = "spring" ];then
saisonfr="Printemps"

elif [ $saison = "summer" ];then
saisonfr="Eté"
fi

echo $saisonfr

curl "http://192.168.0.21:8080/json.htm?type= ... =$saisonfr

To finish i call it everyday with a cron.

Not sure where you got the girl impression from but ... No ... very Male.

Why use the IDX when you can use the standard LUA Event tables like specified on this WiKi page? :
https://www.domoticz.com/wiki/Events

The IDX is only needed for the special devices like when using a Sensor or Text device.
