Hunter Wireless Rain/Freeze Clik irrigation rain and freeze sensor — wireless transmitter & plug-in receiver, 800 ft range

Hunter Wireless Rain/Freeze Clik is a battery-powered sensor-and-receiver set that automatically pauses irrigation when it detects rain or freezing conditions.

Designed to protect landscapes and conserve water, this Clik combo from Hunter pairs a compact outdoor transmitter with a plug-in receiver so your irrigation controller suspends scheduled watering when precipitation or dangerously low temperatures occur. The unit ships with gutter-mount hardware for flexible placement and uses Hunter’s Quick Response sensing to react promptly to changing weather. Because it’s fully wireless and rated to communicate up to 800 feet, installation is fast and doesn’t require trenching or new wiring runs.

How does the Wireless Rain/Freeze Clik stop watering during rain?

The sensor’s moisture-detecting element senses rainfall and sends a wireless signal to the receiver, which interrupts irrigation cycles on compatible controllers. The interruption is automatic and resumes once the sensor dries and stops transmitting the stop command.

• Includes a transmitter that detects rain and transmits the stop signal.
• Plug-in receiver accepts the signal and halts scheduled watering.
• Quick Response helps the sensor react quickly when conditions change.

Will it protect my system from freezing temperatures?

Yes — this combo monitors ambient temperature and triggers a freeze shutdown when the local temperature reaches the sensor’s threshold. The freeze function prevents watering during near-freezing conditions, reducing the risk of ice-related damage to plants and paved areas.

• Freeze detection built into the same transmitter as the rain sensor.
• Receiver receives freeze alerts wirelessly and suspends zones accordingly.
• Ideal for climates with sudden cold snaps or overnight freezes.

How easy is it to install and where can I mount the transmitter?

Installation is straightforward: mount the transmitter using the supplied Hunter SGM gutter hardware or attach it to a flat surface, then plug the receiver into your irrigation controller. No wiring between sensor and controller is required, so you can place the transmitter where it best senses weather without running cable.

• Includes Hunter SGM gutter mount for convenient attachment to gutters or eaves.
• Wire-free setup removes the need for trenching and long cable runs.
• Up to 800' operating range lets you position the transmitter for best exposure.

What controllers and compatibility should I check before buying?

The receiver is designed to work with most irrigation controllers that accept a standard sensor input or dry-contact interruption. Verify your controller’s sensor terminal and power requirements to ensure plug-and-play compatibility, or consult Hunter documentation for models tested with this receiver.

• Receiver plugs into common controller sensor inputs; check your controller manual.
• Works as a dry-contact interruption triggered by the receiver.
• Compatibility guidance available from Hunter if you need model-specific confirmation.

Who is this for: The Hunter Wireless Rain/Freeze Clik is intended for homeowners, landscapers, and property managers who want a low-effort way to prevent unnecessary irrigation during rain or freezing conditions. It’s especially useful where running sensor wiring is impractical or costly, and for anyone seeking quicker sensor response and flexible mounting options for improved water savings and landscape protection.
