Domoticz

Im a newbe with Domoticz , and im trying to add relay contacts PCB to the PI3
https://www.kiwi-electronics.nl/tweekan ... zjEALw_wcB
I selected at Hardware :raspberry GPIO port
Then at Switches i selected type :GPIO , but i i cannot select the OI itself i get :GPIO INIT ERROR
What am i doeing wrong?

You could try the GPIO Sysfs Switches plugin. Then you just have to set the pin number in the interface and you're done.

Make sure your relay is a 3.3v relay / can handle a 3.3v activating signal.

Thanks for help , i think it will work
