How does the controller work?

The controller connects to your home's Wi-Fi to rely on local weather station data and seasonal variation to decide how much water your grass needs.

Check your Wi-Fi strength at your existing controller before purchasing. Fewer than 10% of participants have needed to install Wi-Fi boosters to provide the signal to their controller.

Controllers are operated with smart phones. If you utilize an irrigation company, you can share access with them through the app (no need to give them your Wi-Fi or login information).
