The bulbs are ok but I tried moving my Hue motion sensors over to my main Zigbee network and they were terrible, constantly dropping offline and needing reset.

Luckily Hue is made by Philips who I'm pretty sure aren't going anywhere.

I moved my Hue sensors to my primary Zigbee network and left the bulbs on the hub, especially since I have some of the gradient strips that don't work unless they are on the Hue hub, and my motion sensors have been rock solid.
