I have a two wire rain sensor (brand new). On my old system (Hydrawise) the two wire sensor went into the common terminal and the other wire into the Sensor terminal. I assumed it would be the same thing with this new sensor and the Rachio 3.
The problem is I get “Rain Sensor On” showing in app for a minute or so then off. It cycles like this continuously. Thus pushing out my next water cycle 3-4 days.
How should I wire this two wire rain sensor to the Rachio 3?
