Managed to setup Node Red and I'm getting the input events, but when I try to set an output via MQTT it turns on briefly then back off.
I've uploaded a video of the behavior here:
The Red Lamp (O_2) is connected directly to the input in the main loop of the program.
The Green one (O_3) is supposed to be toggled by MQTT. It is marked as exported in PiCtory.
What am I doing wrong?
Thanks in advance!
