Hunter Rain Clik Review: Is This Wireless Rain Sensor Worth It?

Quick Verdict

The Hunter Rain Clik is a well-engineered wireless rain sensor that does exactly what it promises — it shuts off your sprinkler system the moment rain starts and keeps it off until things dry out. No batteries, straightforward mounting, and a freeze-protection bonus that matters in colder climates. For most homeowners running a standard irrigation controller, it just works. I'd rate it 4.2 out of 5: reliable and maintenance-free, but not immune to placement constraints on larger properties.

What Is the Hunter Rain Clik?

Let me start with the moment I first held one. The Hunter Rain Clik feels solid in the hand — dense plastic housing, no flimsy tabs, nothing that screams "budget aftermarket part." This is a Hunter Industries product, and you can tell. At its core, the WRCLIK is a wireless rain and freeze sensor that talks to your irrigation controller and tells it to pause watering whenever precipitation hits the disc or temperatures drop too low.

Unlike sensors that require hardwiring through your walls, the WRCLIK communicates over a 433 MHz wireless signal to a receiver that wires into your controller's sensor terminals. That means you can place the sensor on a gutter, an eave, a fence post — anywhere within roughly 200 feet of the controller — without running a single new wire. Hunter calls it the "Wireless Rain-Click," and the click refers to the physical contact inside the unit that flips when the hygroscopic disc absorbs water.

Key Features

• Wireless communication with compatible irrigation controllers up to 200 ft away
• Hygroscopic disc triggers automatic shutoff when 1/8"–1/2" of rain accumulates
• Built-in freeze sensor disables irrigation near freezing temperatures
• No batteries required — purely mechanical activation
• Adjustable rainfall sensitivity dial for different climates
• Mounts on gutters, eaves, walls, or fences with included hardware
• Compatible with most major irrigation controller brands via standard sensor terminals

Hands-On Review

After mounting the Rain Clik on my back gutter — a five-minute job using the bracket that ships in the box — I paired it with my Orbit controller by connecting two wires to the sensor terminals. The receiver unit clipped neatly onto the side of the controller. That was it. No app, no calibration wizard, no firmware update. I crossed my fingers and waited for rain.

Three days later a steady drizzle rolled through. I was inside working when I noticed the sprinkler heads on my lawn hadn't popped up. Checked the controller — the sensor indicator was lit. The system had done its job without me lifting a finger. What I didn't expect was how satisfying it felt to watch that little flag drop on the sensor unit, knowing the machine had made the right call on its own.

What surprised me was the drying-out behavior. In full sun the hygroscopic disc contracts faster than you'd think — about 24 hours in typical late-spring conditions. On overcast, damp days it took closer to 36 hours before the controller resumed its schedule. That's configurable to some degree by adjusting the sensitivity dial, but if you live somewhere with frequent misting, you might find the system stays off longer than expected. For my lawn in a climate with distinct rainy seasons, that was a feature, not a bug.

One thing nobody mentions in the listings: the wireless range is line-of-sight. I initially placed the sensor at the far corner of my property — past the shed, behind the oak tree — and the signal dropped intermittently. Moving it to a clearer path closer to the house solved it. If you have a large lot, factor in that 200-foot rating with some buffer for obstructions.

Who Should Buy It?

• Homeowners with automatic irrigation systems who want to cut water waste and lower utility bills without daily monitoring.
• People in climates with frequent rain or freeze events — the Hunter Rain Clik handles both, making it a year-round asset.
• Gardeners who have drip systems or zone watering and need consistent rain shutoff across multiple zones.
• Landlords managing rental property irrigation — the wireless design means no new wiring when installing on existing systems.

Skip this if your irrigation controller doesn't have sensor terminals and you're not willing to upgrade the controller. Some older or very budget-friendly controllers lack that input entirely, which means the WRCLIK simply won't integrate. Check your controller's manual first.

Alternatives Worth Considering

• RainBird RSD Rain Sensor — A wired (non-wireless) alternative that's less expensive and suitable when your sensor and controller are close together. No batteries either, but requires running wire through walls.
• Rachio Smart Hose Faucet Kit with Flow Sensor — A smart irrigation controller approach that adds weather intelligence and app control, but at a significantly higher price point and with WiFi dependency.
• Orbit B-hyve Smart Sprinkler Controller — If you want app-based scheduling and weather-aware adjustments, this is a capable alternative. However, it requires WiFi and is more complex to set up than a simple rain sensor.

FAQ

Final Verdict

The Hunter Rain Clik WRCLIK earns its place in any irrigation setup where water waste and weather responsiveness matter. It installs in minutes, requires no batteries, and handles both rain and freeze conditions with a simplicity that most smart controllers can't match. The wireless design is genuinely useful unless your property spans more than 200 feet of obstructed terrain. For the price, you're getting professional-grade automation that pays for itself in water savings within a season or two. If you have a compatible controller, this sensor is an easy recommendation.
