I have two bulbs that go offline a lot of the times. I have to turn the bulb off and on and wait to get it back. This is not good for my user experience. I have sent an error report through the app.
Is the bulb defect?
I have the same issue with all 5 of my bulbs.
How many devices oyu have on WiFi? I had problems that something went occasionaly offline and it stopped when I bought more powerful router…
i just tried to ping the bulb, seems it is losing connection a lot:

Updating the bulba to the latest firmware made things worse. Now 3 or 4 bulbs go offline
