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.
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').
