What Is the Hunter Rain Clik WRCLIK?
The Hunter Rain Clik WRCLIK is a wireless rain sensor designed to communicate with most irrigation controllers. When it starts raining, the sensor sends a signal to your controller to pause watering. Once the rain stops and the sensor dries out, it automatically resumes normal scheduling. This model also includes a freeze shutoff feature that prevents your system from running when temperatures drop near freezing—ideal for climates with cold winters.
The sensor is battery-powered and mounts easily to a gutter, wall, or fence. It uses a hygroscopic disk that expands when wet to trigger the shutoff, and it’s compatible with virtually all major controller brands including Hunter, Rain Bird, Toro, and more. According to a review roundup by NerdTechy, the WRCLIK is a top budget-friendly pick for adding rain detection to any system.

How to Install the Hunter Rain Clik WRCLIK
Installation is straightforward. First, mount the sensor to your gutter or wall using the included bracket. The gutter mount clips onto the edge of a standard gutter, while the wall mount uses screws.

Why You Need a Rain Sensor for Your Irrigation Controller
Even the best smart watering schedules can be thrown off by unexpected showers. A dedicated rain sensor ensures your lawn doesn’t get overwatered, which can lead to fungal diseases and wasted resources. According to the EPA, up to 50% of outdoor water use is wasted due to inefficient watering. Adding a sensor like the WRCLIK can reduce your water bill significantly.

This sensor is especially useful if you travel frequently or live in an area with unpredictable weather. The freeze shutoff adds an extra layer of protection during cold snaps, preventing your system from running when ice could form on sidewalks or roads.
