Sonoff 4CH Pro R2 - RF


Ordered 30 pieces from 2 different suppliers and we encounter the following.

At inital powering up of the 4CH a LED light goes on. After pairing with the remote the LED light starts flashing. So far so good but when switching of the power the light keeps on flashing whereas before the light would come off. Also the relais keeps on ticking switching on and off at random. Also sometimes it might take more than one push on the remote in order to get it to work.

We have never encountered problems with the previous version......

Switch the switches on the Sonoff motherboard

Done that several times, but that didn"t work. Lights keep on flashing and there is no direct response. See attached video for explanation


if you want the best motherboard then I suggest to visit this site to read reviews and purchase the perfect motherboard. i recently bought one motherboard and it's working perfectly.
