Does v1 of the Philips Hue Bridge support the Cree ZigBee bulbs?
It seems to me you’ve cross-posted in the SmartThings forum.
I’ve learned that Philips Hue cuts support for third-party bulbs.
Sorry. Can’t be of help.
I did cross post because I plan on running my Smartthings with HA
Looks like they reversed that decision too.
