Recently got a 6-pack of Shelly DUO GU10 bulbs, which are dimmable, have a white-temperature mode, and a full RGBW mode.
When discovered in HA via the native Shelly integration, the bulbs only appear as dimmable with a color temperature slider, no RGBW. Additionally, the dimmer and warm-cool sliders don’t work. HA can only turn the bulbs on and off.
How can I get these bulbs to announce their full RGBW capability to HA? And if that’s too much to ask, how can I at least get the dimmer slider to function?
Note that these bulbs do announce their state via shellies/# but do not respond to commands, so MQTT does not appear to be a solution at this point. And flashing Tasmota via https://github.com/yaourdt/mgos-to-tasmota is also not possible.
