There is another issue with this new bulb (color version).
Individually you can set it to music mode. But once you put it in a group, you can't launch the music mode on the bulb (while all my V1 and lightstrip can). When i'm on the group > music mode > list of bulbs/lightstrip, i can press the play/pause button for the old bulbs but for the new one there is a message "Please update the firmware"
Hope you can fix it asap
Btw i really hope that in the future you will release a more brighter version with like 1000/1200 lumen, as to be honnest it's difficult here to notice the +200 lumen increase compare to the previous bulb
But it's nice to see that you fixed the buzzing sound when the color is white at maximum brightness + the CE certification is also good point
