I have a 433-power plug and these cheap sender and reciever modules (https://tutorials-raspberrypi.com/let-r ... s-signals/) connected to two different pies. I have not attached an antenna.
When I press my power plugs remote I get data to my reciever and my plug reacts. Something like:
3492965779, pulselength = 705, protocol = 2
3492965779, pulselength = 708, protocol = 2
3492965779, pulselength = 712, protocol = 2
3492965779, pulselength = 715, protocol = 2
When I send this data from my own send module, my receiver shows the same data as from the remote, but my plug does not react. I have all the components within 5 cm (I also tried further apart).
Could there be more data being transmitted from my remote than the data my reciever are picking up?
Does anyone have any brilliant ideas?
