I have one, but have not be able to get it working myself, I have asked this to be added to the list for future integration, no idea when that might happen though.
It would definitely need a custom device type handler.
You can look at the work to @AdamV did on the DeVolo scene controller, which also uses central scene commands. you can’t use that DTH directly, but at least you can see the coding approach.
Because of the use of central scene command you can’t just get a basic on/off with this, unfortunately. But I would think someone should be able to do a full DTH for it.
I played a little bit with @AdamV 's code and now have the basic push capability I wanted… If I have some time this weekend, I will see what else I can do.
I was actually considering getting one of these at one point.
I imagine that you’ll probably need to make a dedicated smartapp as well to point it to individual devices connected to ST and ensure that dimming / temp / volume status positions get relayed back to the device so that you can get the LED ring to be useful.
