Hydrawise App: Set up a Rain Sensor 

Adding a Hunter Rain Sensor to your irrigation system will stop your irrigation while it is raining and prevent future irrigation if the recent rainfall amount is enough for your landscape. When the sensor dries out, it allows irrigation to resume as scheduled. The Hunter Rain Sensor must be connected to your controller using the SEN ports, so please follow the instructions provided with the Rain Sensor and Controller or online at Hydrawise.com/support.
