I saw the comment about uploading pictures of zones in What's New for the latest update to the Android app, and I had to try it.
Very nice implementation, especially the integration of Google Photos gallery pictures directly into the picture selection. No need to push pictures around to get them accessible to the app, and the ability to size and crop without any fuss is well done.
I don't really have an urgent need to have the pictures to tell me which zone is which, but it's fun to see snapshots of my actual zones on the app, and I really appreciate that Rachio is continuously innovating, updating and improving your product. Well done!
