We could also have fun in cracking all the codes that works. To do so, we could just generate all combinations and see if the plug switches.
Something "sad" is that the plugs first have to be paired. It's just a bit longer.
All of this could easily be done by :
- switching the receiver chip power. It is in pairing process.
- sending it a code (start with the first one...). It doesn't even need any remote, just connect an MCU to it.
- trying to switch it again with the same code and also try the 65535 others. Record when it works.
- do it again
Hum, will I do it... later maybe !
