Hello,

Tried to find solution (google, youtube, this forum), but in the last 2 days I didn't have luck, so I'm begging you to help me achieve the most simple task ever!

Xiaomi YeeLight RGBW color temperature, read WIKI, but as a newbie it kinda misses a few steps, and I might try to do something easy and forgetting a crucial step somewhere.

Domoticz Beta V3.8701 for Synology DS215j

Making the dummy Hardware

Dummy selector switch named : "Color Temperature"

Code I copy-pasted from wiki, and changed IP for the current IP address of the RGBW bulb (fix IP from router with DHCP), I guess the port is fix, so I haven't really changed it.

Changed selector switch to DIMMER and tried to ADD the bulb as a sub/slave, but also tried to do without this step, same outcome.

When I added as a sub, it changed the original Bulb Switch on/off, but in fact the bulb stayed ON all the time, never turned off or on by this, it maybe a helpful info.

Log when I use the dimmer for color temperature, no error messages

Code: Select all

What step did I miss or screw up? :\

Any chance for a little help? I'm really desperate

Please help! me or at least give me some hints!

Try this command

Code: Select all

warm_white=(255*65536)+(172*256)+68
runcommand25 = "sudo echo -ne '{\"id\":1,\"method\":\"set_scene\", \"params\":[\"color\", "..warm_white..", 25]}\\r\\n' | nc -w1 " ..IP.." " ..PORT.."";
os.execute(runcommand25);

where warm_white is obtained with the RGB formula as above (R*65536)+(G*256)+B

in this case you will set the color and the brightness (25)

I've transformed your script in dzVents and it's working fine, included the Off that turns off the lamp.
Just added the off command in case CalcValue is nil

Code: Select all

return {
	on = {
		devices = {
			'ColorTemp'
		}
	},
	execute = function(domoticz, device)

        IP = '192.168.xx.xx';
        PORT = 'xxxxx'
      
        if device.state == 'Off' then -- turn off
            runcommandoff = "sudo echo -ne '{\"id\":1,\"method\":\"set_power\", \"params\":[\"off\", \"smooth\", 500]}\\r\\n' | nc -w1 " ..IP.." " ..PORT.."";
            os.execute(runcommandoff);
       --  print(runcommandoff) 
         
        else
            CalcValue = ((device.level-1)*48)+1700;
            if CalcValue==nil then
                CalcValue=0
                print("CalcValue = "..CalcValue)
                runcommandoff = "sudo echo -ne '{\"id\":1,\"method\":\"set_power\", \"params\":[\"off\", \"smooth\", 500]}\\r\\n' | nc -w1 " ..IP.." " ..PORT.."";
                os.execute(runcommandoff);
            else
                print("CalcValue = "..CalcValue)
                runcommand = " sudo echo -ne '{\"id\":1,\"method\":\"set_scene\", \"params\":[\"ct\", "..CalcValue..", 50]}\\r\\n' | nc -w1 " ..IP.." " ..PORT.."";
                os.execute(runcommand);
                
            end
        end

    	end
}

Do someone know the formula to use dimmer to change color from 0% to 100% on all the RGB values?

Thank you for trying to help me, I really appreciate it!

Tried to copy paste your 2nd code and overwrite the previous one but keeping the IP and port numbers, but the dummy slider switch seems to do nothing.

In the log I get this, but nothing changes :

I imagine you changed the events from Lua to dzVents

and set it to Device, like the image above

Why don't you use a scene ?

I want to, but there is absolutely no option in events to change color temperature :\
using only the RGB colors I can't manage to get that warm color I want to use, it is neutral white or simple yellow, there is nothing inbetween here.
I think yeelight is using different leds for warm-neutral-cold color emperatures.

@woody4165
yes, tried it with that also, in theory it is working, but physically it does nothing for me:

Code: Select all

2017-12-17 19:13:05.271 dzVents: Info: ------ Finished RGBW_dz

Tried to rename/redo the switch and script, the IP address for bulb is fix, I get no error message, it just does nothing.
