Comunication Issue

post by ssouthar on Mar 19, 2025

I have my second Rachio 3 set up now at the side yard. First unit has been working great for almost 5 years now and I love it. Recently added a large lawn and shrubs to the side yard so I got a 8 zone unit for 6 new zones. Got it all set up and talking to the network. Everything is connected and all of the zones run if you trigger them directly from the unit. However, if you try to run a test of any of the zones using the app, it just sets there with the gear spinning saying it us running but it’s not. Any ideas? The lawn installer doublechecked the wiring and it’s all good and I would say that running all zones manually from the box confirms that the wiring is correct? No?

Can you try just having one zone connected to the controller, and add more if the first one works? You could have an open line.

Thanks for the suggestion. I’m not sure what happened to getting it working but it is. I went down and bought an Orbit controller and when I went to disconnect the Rachio 3, I saw that the light bar was solid blue. I decided to try moving the common from M to one of the white terminals and one of the stations started running! Huh?? So…everything seems to be working just fine now. Whew!!!
