I just purchased a 2 channel relay module with a Linx KEYFOB overlay board with a 2 button Fob. Right out of the box I configured each button, and linked it with the KEYFOB receiver. I am only able to get R2 to activate, have had no luck with R1. I get the busy LED indicator to flash on both buttons when each one pressed independently, except only R2 will activate with corresponding button.
I tried to reprogram both the transmitter and receiver, but I have not had any luck. I did not purchase an USB adapter, since I did not need to change any programming, since I only need the momentary function. Thanks!
