Just completed a new install of a Rachio 3 16 Zone. A truly pleasant experience. No problems with WiFi, Scheduling, or anything else. I have experience with competitors models, and Rachio is far the best with setup and scheduling. Time will truly indicate overall quality with other features. So far so good!
I prefer the web for setup and monitoring. One of the reasons I chose Rachio.
Should be considered for improvement:
Delete History (without having to remove/install device);
and Provide contrast to Zone Numbering on Controller Cover.
Best Wishes to all and keep up the fine work.
