I picked up some relay boards that work with sonoff & also have the RF facility. Now sonoff dont make a 10 button transmitter, so i picked up a leaning RF transmitter & all works great. Problem is i put one relay board on the wrong button & cant get it off. Is there a way to unpair the board from the transmitter. I tried to pair another board on the button & it just made 2 boards switch on/off.
I take it this is done at the board end??. Thanks
If there is no instruction and you just need to separate the board from the radio signal, then try to fall out the antenna.
