Home Assistant Sprinkler Automation: Rachio and Beyond
My Rachio controller handles irrigation, but Home Assistant gives the rest of the house one place to see and control it.
This walkthrough shows the finished sprinkler package and dashboard in my Home Assistant setup: controller status, active zone, rain delay, standby, pause, resume, stop, per-zone last-run duration, ninety-day history, and readable Activity Feed entries.
The implementation reads native integration states and attributes before adding derived sensors. Trigger-based template sensors capture a zone's duration after it turns off, so the dashboard gets useful history without an input number or input datetime for every zone.
Rachio is the concrete example. Rain Bird, Hydrawise, OpenSprinkler, and other controllers use different entities and actions, but the same five questions apply: which zone, what schedule, is water running, should it wait, and can Home Assistant stop it?

👋 About this channel: My name is Carlo. I've been running Home Assistant for a BUNCH of years. Almost from the very beginning actually. This channel is focused on bringing what I have implemented at my own house to you so that you can bring it to your house. The channel will be a mix of reviews, tutorials, and inspiration. It is a companion to my GitHub site that holds all the code for my Smart Home and my main site where I keep the more in-depth technical writings. I hope you will enjoy the videos and consider subscribing.

These videos are being made with the help of AI. If you are not into it, that's cool, but this is the only sustainable way for a hobbyist to get thier ideas out to the public and give back to the community without completely losing all thier free time. My promise is to keep them short, to the point, and hopefully instructional and inspirational so you can take the ideas, concepts, and YAML and use them in some way in your own Smart Home.
