If you turn on/off 3 times then they reset themselves

A project log for ESP32-MeshKit custom RGB LED Lamps

Use this RGB Leds that are in your garage to build your own Lights. As simple as Leds, Ω and soldiering (To be safe max. 30 mA per GPIO)

In my home every 2 weeks they enter in this modus. It happens because my wall switches are very old. 

It’s a pity that so far I didn’t found a way to disable this 3 on/off reset. Anyways it’s very easy with the Mesh app to make them join your network again.

Note: For concrete lamps you need to get it out to make a successful Bluetooth connection. It seems WiFi passes through cement but Bluetooth not so good.
