Just hooked up my new Rachio. I had a rain sensor from my previous controller. I am able to test it (push the button) and I can see in my mobile app that it was activated and then deactivated. But then I tried manually running a zone, but pressing the button on the sensor did not stop the water. Does this work as designed? Since I was doing a manual zone, the sensor does not affect it? I am not sure if the sensor actually works. Can I take a cup of water and pour it on the sensor? I'm concerned that the button and wiring are good, but the actual part that detects rain may not be working right.
Any suggestions would be appreciated.
