I would like to know if ita possible use a PIR with the sonoff RF, directly, without the bridge.
I mean, if the PIR send a signal in 433mhz when it detects movements, maybe i could put the sonoff RF in learning rf mode and detect thisz 433mhz signal.
So next time, when the PIR send a 433mhz signal, the RF sonoff relay will detect it and will turn on the light.
It could work??
