Lua virtual device thermostat device change

[Chakkie]

Hi everyone,

I was wonder if Device Change command in Lua also applicable to the virtual device in thermostat type.

For example I would like to turn on a switch / light / or something if the set temperature of the thermostat has been changed.

Some thing like

if Device thermostat = "changed" then

Commandarray = switch == On

Or is there other suggestion ?

thanks

That should work fine. Did you actually give it a try to see what happens as the shown code doesn't have the proper syntax?

Thanks jvdz. No I have not tried it yet. It was just a quick type example. And I don't know the proper syntax either. I could not find the correct syntax for the device change. The wiki page only show the example of device change == on. That's why I was wondering if my idea was possible.

This would be a good point to start in case you want to write LUA scripts: https://www.domoticz.com/wiki/Events

I did something like this but does not work

--Thermostat setpoint
local WNKT = '1 thermostat'
local HSLPT = '2 Thermostat'
local KLNKT = '3 thermostat'

--Maxscript (Virtual switch)
local Max ="Maxscript"

commandArray = {}

if (devicechanged[WKT] == true or devicechanged[HSLPT] == true or devicechanged[KLNKT] == true) then
print('Run Maxscript')
commandArray[Max]='On AFTER 3'


end

return commandArray

The devicechanged table will contain the device(s) changed and their new value while you compare them to true.
try:

Code: Select all

 - Thermostat setpoint
local WNKT = '1 thermostat'
local HSLPT = '2 Thermostat'
local KLNKT = '3 thermostat'

--Maxscript (Virtual switch)
local Max = "Maxscript"

commandArray = {}

if (devicechanged[WKT] or devicechanged[HSLPT] or devicechanged[KLNKT]) then
	print('Run Maxscript')
	commandArray[Max] = 'On AFTER 3'
end

return commandArray

YOU ARE AWESOME.

Thanks a lot.

I though DeviceChanged only respons to 'On' or 'Off'

Hi.
I am using thermostat too.
Here is my examples of my action, if thermostat setpoint is changed.
In my case, it sends command to my device with setpoint value, but you can write your own action.

LUA:

Code: Select all

commandArray = {}
        if devicechanged['Kacka_Setpoint'] then
            DomDevice = 'Kacka_Setpoint'
            DomValue = otherdevices_svalues[DomDevice]
            CalcValue = (DomValue*1)
            print(CalcValue)
            url= 'http://192.168.1.102/control?cmd=event,HeatSetpoint='..(CalcValue)..''
            print(url)
            commandArray['OpenURL']= url
        end
return commandArray 

But I prefer dzVents now:

Code: Select all

return {
	active = true, -- set to false to disable this script
	
	on = {
		devices = {
			'Kacka_Setpoint'
		}
	},

	
	execute = function(domoticz, device)
		
            local url= 'http://192.168.1.102/control?cmd=event,HeatSetpoint='..(device.state)..''
            print(url)
            domoticz.openURL(url)
     
        
	end
}
