Hi Sean, to diagnose the issue, the easiest way is to use the RFToy to listen to your OSPi when it sends the signal, and see if it can decode the signal. If nothing is detected at all, it might be a wiring issue. If it detects the code, but the last four digits (which record the signal timing) is very different, that’s most likely due to a timing calibration issue, and that’s easy to fix by tweaking the last four digits.
