@peekay123, 1k is what I use in all my relays. Damm it, that’s very odd. I remember reading it had to work as you said but when I tried it didn’t. I tested with a couple of arduinos to see if it was my photon and same behaviour . So in the end I went back to that schematic. You say 220, maybe 1k is too much? I will test this weekend just for curiosity.
It could be the relay, but it has been working ok for the last 8 months.
