First one seems to be a truncated version of the legit codes.
Second one is some random stuff.
Looking at some IR code databases, looks like 807F is the prefix for NEC devices, but the second one yields nothing…
So yeah it could be a faulty IR sensor or something? If I could run the firmware in debug mode, maybe I could see detailed logs from the irReceiver() to be sure.
