@luz Hmm, thanks. That thread seems pretty inconclusive, though. The original poster said that he hit it and it eventually started working again, which doesn't seem ideal.
@Gabriel-Ongpauco Is the Relay Expansion faulty?
Hi. I've been using the Relay Expansion to switch the pump for my garden pond on at off at an interval.
The other week I noticed that it was on constantly. I assumed it was a software problem, but after investigating, realised that the relay still seemed to be switching on and off, but somehow the circuit is remaining closed.
I rewired to used the other channel on the Relay Expansion and that was working fine for a week or so, but the same thing has just happened. The electricity is constantly on, even when the relay appears to be switched off.
Has anyone experienced this before?
