I need to set custom color on RGB bulb, i have 3 virtual dimmer, which levels represent the RGB components
how to convert the level decimals into corresponding RGB string ?

Thank you, but where in the rule machine do i add the code please?

you didnt ask for rule machine (sorry didnt see that was the rule machine forum) that is code for a device driver.

what commands does your device support (post the device panel) this will determine what you can do from rule machine.

if it only has level it sounds like the device driver you are using (maybe the wrong one) does not support rgb

yeah, my bad, i ASSume too much :slight_smile: the driver allows for rgb setting as #RRGGBB hexa string and i have 3x level number :-/ i wonder if i could somehow shoehorn the code into RM custom action invocation, tried to avoid creating app ; appreciate the help!

Using Advanced Zigbee RGBW Bulb on physical Gleedo controller that controls 3 independent strips, and to control it i am trying to use 3 virtual dimmers
