Looking for a quick and easy way to reduce your outdoor water use? Get a rain sensor! A rain sensor detects when it is raining (or has recently rained) and will send a signal to your sprinkler control clock to not water. Once the sensor dries out, your sprinkler system will resume it’s usual watering schedule.

“This is a fantastic program. The Rachio is super helpful when I’m traveling. It monitors the weather for me to make informed scheduling, but I can also decide to add or cancel watering from afar depending on what I think my yard needs. It’s an excellent way to monitor. Thank you for this program.”

“The technician who came out to install the smart controller was great. They provided some basic training on setting up the schedule on the app. I really appreciate this program, and I’m glad to know I am conserving water.”
