Mysterious black box..whats inside?

So I monitor mine with an AM radio nearby, you can hear the morse-code like speed of the communication of these units, im thinking mine are at about 50b with mains AC. p

Hi, cloolalang, Even I had the same doubt, in the beginning.I just understood the basic and i assume, thats the main controller where the FSK (Frequency shift keeying) happens which you heard. feel free to correct me if i am wrong :)

I gave up using these units in my project in favor of radio based devices. Reasons: 1) Comms too slow. 2) Limited by noise interference on power lines 3) ISM-band Radio is cheap, well-supported and much faster: Lora peer-peer (Mysensors) Ebyte uart radios radioshuttle

yes completely agree, I had to use many filters to get the actual data. all the best for your project.
