Smart Irrigation Controllers

pdf Smart Controller Application (601 KB)

Smart controllers customize watering times for irrigation systems based on the climate, temperature and evapotranspiration rate.

The smart controller replaces your existing sprinkler timer.  Like your existing timer, it tells you sprinklers when to come on and for how long, but this device uses its attached weather station to adjust the watering times based on the weather that day.  

Thanks to an agreement between Desert Water Agency and CPV Sentinel, DWA can provide and install smart irrigation controllers to customers at no cost to them. 


To participate in the program, customers will need to fill out this  application pdf (601 KB) and submit it to This email address is being protected from spambots.

Once approved, DWA staff will contact the applicant to set up installation of the device. A condition of approval is agreement to allow DWA and CPV to track water use in order to track results from this program. 

5 Tips for Your Smart Controller
1. Programming check. Be sure that you check your programming occasionally to see that the settings haven’t changed. Remember DWA customers are only allowed to water Monday, Wednesday and Friday before 7 a.m. and after 7 p.m. Remember your run time should be set for the MAX run time for summer.
2. Clean off. Your weather sensor may not be working if it is covered with debris. Make sure that you clean the area around your sensor on a regular basis and check after storms to be sure the wiring in intact.
3. Don’t bypass. Make sure that your switch is in the active mode. If it is in bypass mode your rain sensor will not work and you may end up getting a penalty for watering during the rain.
4. It’s ok to shut off. When we get a good rain (like we have been lately) and there is rain in the forecast, don’t shy away from turning the controller off for a few days (or weeks). The rain sensor is on your roof in direct sunlight so it may dry out a good deal sooner than your soil.
5. Power up. Check to be sure that the power supply for your device is working. Also, make sure that your backup battery has been changed in your smart controller, that way if the power goes out your programming is saved.
