      Hi,

      Any views on using a separate 5V PSU (already powering an RPI) in the BigBox and a relay module to power the main 24V PSU by PS_ON?

      Since the relay module wants high on CH1 to trigger I wire it to permanent 5V then wire PS_ON to GND on the module. I have tested this on a breadboard to work.

        How about a DC-AC SSR with the control terminals connected between +5V and PS_ON? I haven't tried it yet, but I think it should work.

        Some relay modules have optically-isolated inputs. Those could also have the input connected between +5V and PS_ON.

          I dont have any SSRs laying around. But this relay is opto isolated. Think I'll give it a try and can replace it with an SSR if it does not work.
