After installing ESPHome on device and testing is RF module still working - have one issue.
Looks one channel is learned some RF code, which is transmitted ~periodically, probably by some alarm or etc. system nearly around. But I can’t erase that code from channel. When I follow standard procedure - channel still have it, may be it is too short/weak for clearing process ?
Now channel flipping time to time. After installed original Sonoff firmware back - still the same.
So, looks this is not firmware issue, but RF chip activating button.
Tried to sniff RF packets. When using bad noisy RF receiver - 4CHPROR3 channel not flapping, IMHO receiver noise blocking weak signal.
Is someone have any idea to clear RF chip ?
Any help appreciated.
