i was able to use those cheap 433Mhz modules XY-MK-5V to read and send commands to a wifi wall plug.
Now i want a single piece which is able to send and recieve 433Mhz signals and i found the HC-11 module but i couldn’t find a manual how to read and send to control the wall plug.
Is it possible at all? Can this module combined with the rc switch lib?
Is there another transciever that can?
thx for your help
