I have the same problem that Rain Sensor Activated and all the schedules are skipped. I had my new Irrigation system installed. The Rain Sensor issue started after 2 or 3 days. A dashboard message started. It will not go away until you have disabled the sensor from the App. I have done all the troubleshooting scenarios. No change in Dashboard message. There has been any rain in the past 30 days. I have checked the wiring and I have connected to S1 only, not together as S1 and S2. I had a generation 2 Rachio. Plz help.
