Have you « reactivated » your bulb a bit?
I know that on some Z-wave devices, there is a small button that sends all the information back to the controller when you click on it…
I just thought about it, the feature for managing white temperature and color isn’t released in the official version yet? Since it’s an RGBW LED, that could explain it.
That doesn’t explain why I don’t have the ON/OFF option though.
EDIT: I just went to look at the OpenZWave database (is that the library being used?) and I don’t see my model in the list. But in that case, why can I control it in Domoticz…
