Sorry to take so long in getting back, but b-u-s-y days of summer.
The sensor I have is a Toro 53769.
I didn’t have it enabled in the accessories section. However, when I did activate it, the next issue is that the Rachio3 saw it as still wet, even though we haven’t had any rain in two days; so it was disabling the schedules. Hmmmm. Not sure if it is the sensor or the controller.
Thanks again!
