All works nicely except the RPi 0W doesn’t seem to have enough speed to handle -H frequency skipping and sending to MQTT. BUT: If I’m changing state manually from off to on, the physical switch works fine and the signal is properly transmitting. This will most likely work with all popular low cost power outlet sockets. Unlike most receivers of its type, this uses just 100µA, giving your device a potential standby battery life of 4 or more years. They contain encoding chips like the Princeton Technology Corp PT2262 which converts the button pressed and address settings into a series of pulses which is then transmitted over whatever frequency and modulation that the designer chooses. A end code marks the end of a sequence. It produce everything in one topic. The ev1527 protocol is pretty popular.
