Indeed, this is happening in Lebanon also with several devices randomly. We tried to delete the devices and pair them again, it didn’t work for the Mini R2 and the 4ch pro. Tried to change the SSID and paired the devices again, no luck!
The devices are randomly restarting going back to their power-on state; we don’t know what is the trigger. And, in inching mode, the relays are providing power for around a second and then it cuts off.
Things are getting so weird, we are thinking to remove all the sonoff products and install another brand because this is unacceptable.
