I’ve encountered the same problem allthough I use Mi-Lights instead of the Philip Hue. (I thought it was a Milight problem, but I guess it’s an MQTT problem) I could not set the hue of the light:
Eventually when no-one could lead me to a workable solution, I created a workaround. It uses HomeyScript to translate custom MQTT messages to setting the colour:
It’s not pretty, but it works. If I activate a light a extra panel appears to set the light colour and brightness.
I’m using simple coloured buttons. In my opinion this is more touch friendly than the colour picker. I still should give this a graphic overhaul with more colour choice, but to be honest, I hardly use the direct setting of the lights. Most of the time I just set a scene.
Later in that topic user @xAPPO profided some hint’s. But I still had a hard time how to formulate the message to send. And since I had a working solution I did not explore it any further. If you find the right topic / payload please let us know!
