I don’t know if you will be able to tell me:
I bought a SONOFF Dual R3 to pair with a roller shutter motor (delta dore rollia motor).
On the engine documentation it is noted:
black: local push button option…
Basically, black is not connected because I use a delta dore wireless remote control
My wiring is as follows: (the 3 wires on the left are those of the motor, the 4 on the right those of the ‘wall’)
Result, impossible to operate with the ewelink app: Nothing works on the telephone/roller shutter level despite the different modes used.
Only my wireless remote control always works but only in the ‘closed’ position in the app
Could you give me a little help?
