I wanted to ask if there was a browser based access to the Rachio not just the app?
It would be great to be able to do configuration and scheduling using a browser and display space 
If you go to Rachio.com and to the bottom left of the page, you will find a Web Login. Just be aware that not everything supported from your phone is supported on the web app, known bugs exists, and no work is being done on it at this time.
