this works great for my setup:
- Raspberry pi3b+ before and Raspberry pi4b now
- Official 7" touchscreen


Thanks Skirmo, I really preciate it. I am pretty new to RBP projects, could you guide me a little on how to install the scripts? Im sorry for bothering you so much recently. :/

(10-18-2019, 05:57 PM)skrimo Wrote: No problem

Install OAP, then exit oap and open terminal.

First type these two lines
sudo nano relay.py (and paste in relay code)
sudo nano switch.sh (and paste in switch code)

Then
sudo chmod +x /home/pi/relay.py
sudo chmod +x /home/pi/switch.sh

Then
sudo nano /etc/rc.local

And write these two linea before exit0
python /home/pi/relay.py &
sudo /home/pi/switch.sh &

Finally
sudo reboot


Now it should all work if your wirring is corrent
