Thanks. Yea being a pi 4 and I’m using wifi I already had the pis power connected with the opensprinkler transformer.
Confirmed with multimeter 0v is there.
I’ll try running the opensprinkler program as pi user. Maybe that fixes something.
I had just ordered new board causf my prior was doing same and thought maybe I messed it up on assembly.
But I am using same configured rpi so maybe its software side.
