My Rachio 3 had been working fine for months. The connection to network is fine and the app is functioning. I have manually checked each valve for the sprinkler zones, (they are working) however when I activate via the app - the sprinkler start once and promptly turn off. The app shows running but the sprinklers are not on. I swapped the common C terminal and nothing changed.
Is this for all zones in the system?
Yes
