Same bulb here and did as instructed. With the advanced driver only “on” and “levels” respond. With the generic driver proposed I can only turn it on or off and nothing else. No color or temperature whatsoever. Any other ideas?
Got some of these bulbs and managed to get the generic zigbee rgbw bulb driver in and configured. But was only able to use them by using the device page which controlled the bulbs in all colours and brightnes plus on and of, and by use of a basic rule. When trying to use a motion or mode rule they would not work at all. Have given them up as a bad experience.
If you have a Hue hub, try connecting the bulbs to it instead of Hubitat - then control the bulbs via the Hue Bridge Integration. I have some 'tiny' dogain bulbs that behaved as you described - I could never find a driver that worked. Hue does.
Just had a breakthrough, in my motion rule i set the rule to turn on as a switch but named the bulb as the device and it now works fine. I was telling the rule to turn on as a bulb and it would not work. It only twigged when I could use the bulbs in a basic rule which set the device as a switch.
Happy Days and thanks for the suggestion
