Hi, sorry if this is a repeat post, I have found a post for Rain bird RC-7Bi to Rachio-2, but nothing for Rachio-3. Is it possible to replace Rain Bird RC-7Bi with Rachio 3, has anyone done that?
No problem with compatibility. The RB has only 7 zones and Rachio 3 models start with 8 zones and go up from there. The connections on the Rachio 3 are the same as on Rachio 2. They are in different locations but have the same labels and function the same.
