Engrighten Z-Wave bulb shows up as light.ge_unknown_type4c42_id3031_level_8_0
Flipping the switch off on the frontend turns fades the light off, but the UI says the brightness is 85 - the slider gets there in two steps. Flipping the switch back on doesn’t turn on the light bulb and the UI still reports brightness 85. Flipping the switch back off turns the brightness to 0. Flipping the switch on turns the bulb on but it only reports brightness 5. Flipping it off reports brightness 85 again.
The switch in the UI can’t reliably tell me whether the light is on or off and it has to be flipped a couple times to turn the light on. But, it works without a problem in automations using light.turn_on with brighness 255 & homeassistant.turn_off as well as turning it off with Alexa through emulated hue. Automations using light.turn_on without brightness will set the brightness to weird values, like 3, when the light is clearly at 100%.
