Just purchased the Rachio 3 12 Zone from Costco. Easy set up and had a bit of a struggle getting hooked to wi-fi with my iphone, but thanks to this Community, I was able to get going.
I love this thing. I have 10 zones in my yard! So if I did anything to a sprinkler head, I would have to run back and forth into my garage to run zone. What a pain. I did have an awesome rainbird controller but no wifi. With the Rachio 3, I can set any zone to run from my phone. Thank you Rachio. I have already recommended it to my neighbor. He will probably buy one.
Thanks everyone for your posts and help with technical issues.
