Stopping usage of Rachio Entirely

Hello - I am no longer interested in using Rachio due to the previous homeowner having an old device that wasn’t working well. I did not install or purchase the device for the home - what have others done to stop using Rachio? Do they use another controller that is more robust? Or simply install standard sprinkler running systems?

Do you have the Rachio 1? I’d just replace it with the latest - Rachio 3. I replaced my Hunter with the Rachio 3 and couldn’t be happier. Right now you can sign up for texts from Rachio and get $40 off a controller.

I mean, honestly, there are simpler smart controllers on the market, but I’d argue that there are none more robust that Rachio.

What wasn’t working well about the old unit?
