Just want to chime in with all the other people who have posted about their Tapo bulbs losing their configuration regularly. The three I bought 18 months ago did it continually until I just gave up reconnecting them. Tried again recently to see if any firmware revisions have fixed the problem but they still do it.

- One day they're working, then the next time I turn them on they flash to show they're not connected (and not visible in the app).

- They all do it, as far as I can recall, roughly together (they're in the same fixture).

- They're in the same room as my wi-fi router, 12 foot away, with direct line-of-sight (apart from the lamp shade).

- They're all on the latest firmware.

- They're all connected to 2.4GHz wi-fi.

I've used a lot of TP-Link stuff over the years but I really can't see me purchasing any more of your home automation kit if this never gets fixed.
