I should also add that I don’t think weather adjustment has anything to do with the problem. I had forgotten where to find the ignore rain toggle. Ignore rain, however, IS checked. I also tried resetting the configuration to default thinking maybe something bad happened when I imported my old config. Still get the same results. The master valve won’t come on when OS detects rain.
Thanks for looking into it! Let me know if I need to do some testing from my side.
