I was displeased with my Blossom Smart Controller and chose the Rachio 3 because it interfaces with Apple’s HomeKit. Comparing it to the Blossom, it was straight forward, intuitive, and simple. I remember having to fight for over 45 minutes trying to connect Blossom to my wifi; too many confusing steps. The Rachio 3 was easy to install, connect and program. I hope it works half as good as it installs.
