I did some tests on my PI 4 and wasn't sure if something was wrong with one of the GPIO pins so I sent it back and they sent me a new one. I have tried plugging the energenie pi mote board onto this the PI 4 and it still doesn't work. Does anyone know if the pins on the Pi 4 are the same as on the Pi 3 (I mean is it backwards compatible)? Does anyone else out there have a energenie pi mote working on a Pi 4?
This is the board I'm talking about https://energenie4u.co.uk/catalogue/product/ENER314-RT
