Little help with script for CO2 [Solved]

[domogijs]

Hi

I am no progammer and can use a little help with this script

The idea is that my ikea lamp turns red when co2 is to high.

I have made this script

Code: Select all

return {
    on = { devices = { "CO2" }},
    
    execute = function(domoticz, device)
        Ikea = domoticz.devices(792)
        
        if  (domoticz.devices('CO2').CO2 > 800) then
            
            Ikea.setColorBrightness(100, 100, 5)
        else
            Ikea.switchOff()
        end
    end
}

But i get errors in the log.

Code: Select all

What is wrong in the script?

Hi,

Try with (domoticz.devices('CO2').co2 > 800) instead of (domoticz.devices('CO2').CO2 > 800)
It is case sensitive and .co2 should be lower case

yes! works thanks for taking the effort pointing this out.
