Today I replaced my old Rainbird controller with a new Rachio G2 8-zone controller. All was well with the Rainbird. None of the 5 zones activates with the Rachio G2. The Orbit zone controllers have never given me any trouble.
Everything looks right using the Rachio web site and the iPhone app. The controller is on my wi-fi network. The lights looks right too. Other than the obvious, I can see nothing wrong. Any ideas?
