Not sure if my title is right or not. More specifically how does Alexa relay the commands to SmartThings? Here is what I’m trying to figure out. I recently added RGB and RGBW LED support to the ST_Anything project so it can be used for lighting. The RGB for example has a standard dimmer control …

So the question is what is being called in a “standard” DTH like Hue or Lifx? Who from SmartThings can we tag that might be able to answer? EDIT: May have figured it out. I manually added a new bulb called “Test Color Bulb” using the LIFX Color Bulb device type. I then added it to Alexa and tur…

For my lights (through SmartThings), Alexa can control colors. I have a TP-Link LB130 that is only connected to Alexa through SmartThings. I do not have color commands defined in my DTH. Instead, there is a color wheel returning six hex characters. Somewhere, the color blue is automatically conv…

Yeah…I don’t get it. I never see a failure in logging or anything and like I said Alexa says “Ok” like it took the command. My color control converts to hex and sets the light, same as the quick commands. So if you click the “Blue” button it sends a #0000FF for blue. If you click Blue within the …

Still can’t figure out why this isn’t working. I looked at your DTH and I don’t see anything out of the ordinary. My DTH does support “Color Control” and I wouldn’t think it needs color temp. If anyone else has any suggestions please let me know.

More than likely you will need to forget the device then rediscover it so it knows that it is a color control. However with custom DTHs it may be hit and miss. Hope that helps.

So it should just “work” correct? Does it matter that I’m using a bunch of defined commands for the colors? I guess the better question is how does Alexa send a command for a bulb that doesn’t specifically have color commands defined? I’m sure Alexa isn’t converting to hex so I imagine it sends “…

Again if it is a custom DTH it will be a crap shoot if it works or how the colors are translated

SetColor is the way but I’m not sure of the list of colors. I believe that comes from the voice provider. Maybe @Jim will know for sure

The color bulb is the TP-Link LB130. I wrote the Service Manager and DTH for this and others in the link below.

TP-Link Bulbs and Plugs Control.

I also have osram lightify bulbs, but not color.
