Turn on the light at the circuit breaker. Then when the light starts 'breathing' press and hold a button on the remote until there's a beep or you get control (will stop 'breathing').
Hi. I also have the same problem that I connect reconnect the SOnoff D1 devices to their rm433 devices (I have two in the one room). I had one working fine and then added another into the room. I wanted separate rm433 control of the second dimmer. When pairing to the second dimmer it paired to both dimmers (why I dont know). I decided to long press the reset button on both and then power each one up to pair with their remote. Now I cant get either to pair with the remotes. Wifi connections works OK. Is there a method to factory reset the RF as well as wifi pairing?

Sorry, I do not understand the sonoff-video showing pairing D1 and RM433. Can anybody describe in words what to do? My D1 is already paired with the wifi network and the app. Now, I want to additionally pair it with RM433.
