Can I Use a Soil Sensor?

Yes, using a soil sensor with Hydrawise works on all models of controllers.

The Soil-Clik simplifies soil moisture sensing. The Soil-Clik probe uses proven technology to measure moisture within the root zone. When the probe senses that the soil has reached its desired moisture level, it will shut down irrigation, preventing water waste.

Soil-Clik has two components: A moisture sensor probe, which is placed in the soil, and an electronic module, which communicates with the probe and the controller. The probe is easy to install – simply bury it to the correct root depth for your plant material. It can be placed up to 1000 feet from the controller. Easy push button operation allows adjustments to the desired moisture level, with an immediate update of actual measurements.  From more information, see documents page here.

Hydrawise has the soil sensor already setup in the App.  Using the default soil sensor setting will prevent irrigation when the soil is wet.  Alternatively, you can create a custom sensor to start irrigation when the sensor is dry.  From more information, see support article here for setup.
