You can try moving them over to the hue bridge, change your WiFi router channel so there will be less interference with the ST hub or move your ST hub to a different location.
I’ve had about (20) of them for about a year and they’ve worked very well. I even have had 5 or more of them outside over the winters up here in upstate NY and they were flawless. However, over the last day or so, they have stopped reporting the percentage. They dim up and down and turn on and off as before without issue. They just don’t report what percentage they are at.
Ditto. Though I only have about a dozen GE Link bulbs that I’ve been using since late September 2015, with a Hue bridge at first and then with my ST v2 hub (after giving the Hue bridge to my daughter) and they’ve performed flawlessly with both controllers.
I learned long ago to only use GE bulbs in places where I could easily power cycle them. Since V2 I think I have only had to completely reset one a couple times in the last year. Before that it was almost a daily routine on Securifi and Wink hubs. At least 1 would drop off.
Past couple weeks though even my Osram bulbs and 1 of my Hue strips ( connected to Hue hub) have need to be powercycled. So I definitely have something in the area messing with my meshes.
