Hi, I have the RPi4 setup and running using the Sainsmart 8-relay 5v model. Reef-pi turns the relays on/off. I see the light come on (I rigged up a test outlet). however when I turn off the relay the outlet stays powered. If I tap on the relay lightly with my finger, the light goes out. Light a stuck relay. This happens on all the relay modules.
Could this be a power issue? I’m using a 5v 2.0a power supply. what I don’t know, does the high voltage side of the relay get it’s power from the relay board or from the connected high voltage? Or did I just get a bad board of relays? Everything else seems to work fine.
thanks.
