Orbit Wireless Rain/Freeze
$7 under your budget
The only wireless rain+freeze kit under $80 — $19 below the Hunter WR-CLIK and $41 below the Irritrol — and on a lot where the eave sits 40-60 ft from the controller you would be paying for range you cannot use.
Fit ledger — need → measured evidence
■ The catch — co-equal billing, always
You can order the wrong one in two clicks. Orbit sells the hard-wired sensor and this wireless kit as two child ASINs under one nearly identical Amazon title at wildly different prices — the wireless unit is B0FWNPB76N at $73.02, the wired 57069N is $13.71. Past that: threshold-disk sensing rather than first-drop Quick Response, a claimed range under a quarter of the Hunter's, and the thinnest installer track record of anything on this page.
Dealbreaker? Runner-up Hunter WR-CLIK is a single unambiguous SKU with 800 ft and instant triggering — **$92**, $19 more. ↓
■ Every product has a catch. Verdicts that hide it are how bad buys happen.
Don't buy this if…
- you want a Wi-Fi smart irrigation controller (Rachio, B-hyve, Hydrawise) that uses local weather forecasts to skip watering — these often replace, rather than pair with, a physical rain sensorSmart sprinkler controller verdict →
- you have a non-irrigation rain sensor need (e.g. closing skylights, automotive wipers, or weather station rainfall logging)
- you have a soaker-hose / drip system on a battery hose timer with no sensor input terminals
- you specifically need a soil-moisture sensor (root-zone-based shutoff) rather than a rainfall sensorSoil moisture sensor verdict →
Wrong product for you is still a bad buy. These are the cases where we'd send you somewhere else.

Traps — this verdict avoids
Why the Orbit Wireless Rain/Freeze is right for you
It avoids every trap below — and for two, under $80, it is the pick because it delivers:
Your controller may have nowhere to plug it in
A universal rain sensor is a switch spliced into a 24 VAC controller's normally-closed sensor terminals, or into its common wire. Battery hose timers and proprietary smart hubs — Rachio Smart Hose Timer, B-hyve faucet timers — have no sensor input at all, so no sensor on this page will work with them. Open the controller and find the SEN or COM pair before you buy anything.
One Amazon listing, two different sensors
Orbit sells a hard-wired child ASIN and a wireless child ASIN under one near-identical title at very different prices — the wireless kit is B0FWNPB76N at $73.02, the wired 57069N is $13.71. Hunter is the same shape of trap the other way: WR-CLIK, WRF-CLIK and WM-CLIK are three separate SKUs with different sensing behaviour, not trim levels of one product. Check the variant selector, not the title.
It reacts. It never forecasts
A hygroscopic-disk sensor triggers after enough rain has landed on the disks to swell them, and needs roughly 19 hours to dry out and release the controller again. It cannot skip the 5 a.m. cycle the morning before a forecast storm — that is a weather-based controller's job. Buy a rain sensor to stop watering during rain, not to plan around it.
