Hi Ray, thanks for the reply. I figured the pins out from some of the python code in the repo. My RF transmitter arrived today (ordered from you), so I will try that later.
I noticed my rain sensor doesn’t respond well. It will report normally closed fine, then open when I fill it with water or cross over the wires. It will only do this once, so OpenSprinkler has a permanent “rain delay” set until I reboot the Pi.
If I run Dan-in-CA/SIP on a different port, the rain sensor will report open/closed repeatedly fine which makes me think it is software and not hardware related.
Do you have any suggestions on what could cause that?
