ReviPI MIO and external relay board

Post by jonerefsnes »

Hello all,

Newbie question, ive used a normal pi 4 with node red to a simple task to controll some actuators for some windoes in my greenhouse, so i figured id go more robust and bougth a revpi connect with a MIO module. But im struggeling to do the same simple task, use node red to output to high to activate an external relay. (the same way as a normal rasp pi would have GPIO X to high. Ive tryed the 4 digital outputs, and ive tryed to put one of the outs as well, but cant seems tto "break the logic" here. I can turn the led on the PI on and off so i know the node red side of stuff is working.

Appreceate any help.
