Connecting Soil or Rain Sensors

Wyze Sprinkler is compatible with many rain and soil sensors. The wiring will depend on the type and brand of sensor. If your brand of sensor is not listed below please contact your manufacturer or follow these steps:

Wired sensor usually comes with two wires. One wire is for the sensor signal input, and the other for the common terminal. Please connect one wire for S1/S2, and the other to VAC(-).
Wireless sensor uses 24VAC power to drive the receiver. Two 24VAC power wires go to VAC(+) and VAC(-). The wireless sensor provides two additional wires for the sensor common and sensor signal. The sensor common wire should connect to VAC(-) and the sensor hot wire should connect to S1/S2.
The wire colors varies by sensor brands.

Note: Rainbird SMRT-Y wireless soil sensor works differently than other wireless sensors. It requires wiring both the User Interface (with LCD display) and the Sensor. The wiring can be connected to ANY ZONE wire. We are going to use ZONE 1 to show the wiring steps.

Sensor wiring:
- Disconnect ZONE 1's zone wire from its solenoid wire.
- Black wire from the sensor connects to ZONE 1's solenoid's wire.
- Red wire from the sensor connects to ZONE 1's zone wire.
User interface wiring:
- Orange and Black wires from the user interface are the power wires of SMRT-Y connecting to VAC(+) and VAC(-) respectively.
- Green wire is the sensor zone wire for sending the watering signal to the SMRT-Y sensor. It is connected to ZONE 1 terminal in Wyze Sprinkler.
- The ZONE 1's zone wire goes to SMRT-Y's user interface OUTPUT zone wire in Red.
- Instead of connecting the common wire from the solenoids to the "C" terminal in Wyze Sprinkler, it should go to the user interface's common wire (in White) by using the wire nut connection.
