f.lux style light management

[foxingdemon]

I tried to search on the forum but couldn't find. Has anyone got a solution to control Yeelight lamps like f.lux does with Hue. Or using f.lux API?

That's how I do it with my milight bulbs:

Code: Select all

return {
   on = {
      timer = { '20 minutes before sunset', '10 minutes before sunset', 
                'every minute between sunset and 21:30'}
    },
   
   execute = function(domoticz, roomSwitch)
    local Time = require('Time')
    local currentTime = Time()
    Stunden = os.date("%H",os.time(currentTime))
    Minuten = os.date("%M",os.time(currentTime))
    GesamtMinuten = Stunden*60+Minuten -- minutes today from midnight until now 
    Differenz = 1290-GesamtMinuten -- time between desired EndTime of transition to WarmWhite (in minutes, calculated hour*60+minutes) and current time (in minutes)
    LightTemp = -1/3*Differenz+100 -- calculation of LightTemp according to time of the day. Transition starts 5 hours (300 minutes) before desired end time
      
    if (currentTime.matchesRule('at 07:00-21:30')) then domoticz.devices('RGB-CCT 2').setKelvin(LightTemp)
    end

   end
}

The problem I have is, that the light is automatically turned on all the time - even if I don't want it to be. My dream is: I can manually turn on the lights by using the remote/milight-app and the script only adjusts the color temperature.

I guess the reason is the command

Code: Select all

//First send ON , sleep 100ms, then the command
Send_V6_RGBWW_On(pLed->dunit, 100);

(https://github.com/domoticz/domoticz/bl ... itless.cpp) that is sent all the time before the actual command.
Why is this written this way? It's not the behavior that I know from the remote/milight-app, where I can press the color/... buttons but the light doesn't turn on - since I don't want it to be turned on.

Could this specific code been taken out before all the different functions (like switch to white, choose color, ...)? If I want to have the lights turned on in a script I can add this command by myself.

If not: Is there a workaround so that only the light temperature (or everything else) can be controlled without turning it on all the time?

Try something like this. There might be syntax errors in the script, but the idea might work.

The script is now actived by a switch command. Which set the kevin value every minute.

There are still some flaws in the script, if sunset is after 21:30 you encounter errors (negative time).

Code: Select all

return {
   on = {
      device = {'RGB-CCT 2'}



    },
   
   execute = function(domoticz, roomSwitch)
    local light = dz.devices('RGB-CCT 2')
    local Time = require('Time')
    local currentTime = Time()

    -- Cancel All Commands to light
    light.cancelQueuedCommands()

    Stunden = os.date("%H",os.time(currentTime))
    Minuten = os.date("%M",os.time(currentTime))
    GesamtMinuten = Stunden*60+Minuten -- minutes today from midnight until now 
    Differenz = 1290-GesamtMinuten -- time between desired EndTime of transition to WarmWhite (in minutes, calculated hour*60+minutes) and current time (in minutes)

   if (currentTime.matchesRule('after sunset') and light.state <> 'Off') then

     for i = 1,Differenz,1 do

       LightTemp = -1/3*Differenz+100 -- calculation of LightTemp according to time of the day. Transition starts 5 hours (300 minutes) before desired end time
      
       light.setKelvin(LightTemp).afterMin(i)
    end
  end

   end
}

Good idea!
But I guess that the command

Code: Select all

if (currentTime.matchesRule('after sunset') and light.state <> 'Off') then

only works if I turn on/off the bulbs through Domoticz and not by the remote/app, right? Because the bulbs don't send a state change to the box/Domoticz
