Hyper Pet Wireless Rain & Freeze Sensor Kit WR2-RFC — LCD Display, 24VAC Compatible, Adjustable Thresholds

The Rain Bird WR2-RFC is a wireless rain and freeze sensor kit that automatically pauses irrigation when preset rainfall or low-temperature thresholds are met.

Designed for quick DIY installation and reliable remote detection, this kit pairs a weather sensor with an easy-to-read LCD interface and a versatile mounting bracket. It works with most 24VAC irrigation controllers (except specific Rain Bird smart controllers listed), giving homeowners control over when sprinklers run so you can cut unnecessary watering while protecting plants from freezing conditions.

How does this sensor stop irrigation when it rains?

The WR2-RFC senses accumulated rainfall and sends a wireless signal to your irrigation controller to suspend scheduled watering when your chosen rainfall threshold is reached. You choose from adjustable rainfall settings so the system responds the way you prefer, preventing overwatering after natural precipitation.

• Adjustable rainfall threshold from 1/8" to 1/2"
• Wireless communication compatible with standard 24VAC controllers
• Icon-driven LCD shows current rain accumulation and signal strength
• Can reduce water use by up to 35% with proper settings

What protects my irrigation during freezing temperatures?

The WR2-RFC includes a freeze sensor function that halts irrigation when ambient temperature drops below your selected set point. This helps prevent water from running onto plants or surfaces when freezing could cause damage.

• Temperature set point adjustable between 33°F and 41°F
• Immediate shutdown signal prevents scheduled cycles during cold snaps
• LCD displays current temperature and battery status
• Useful for late-season watering control and frost-prone yards

How easy is installation and ongoing maintenance?

The unit is built for one-person installation and mounts either to a gutter or to vertical surfaces like fences and walls using a self-leveling bracket. Battery replacement is tool-free and does not require disassembly, and dual antennas improve signal reliability so you rarely need to reposition components.

• Self-leveling bracket fits gutters or flat surfaces (mounting holes 6.25" apart)
• Simple, icon-driven programming on the LCD—no complex menus
• Dual antennas reduce interference from radios, phones, and power lines
• Mounting hardware not included—bracket supplied for flexible placement

Will this work with my irrigation controller?

The WR2-RFC is compatible with most standard 24VAC irrigation controllers from Rain Bird and other brands, so it integrates easily into typical residential systems. Note a few Rain Bird smart controllers are not supported, so check compatibility before purchase.

• Compatible with most standard 24VAC controllers
• Not compatible with ESP-SMT, ESP-SMTe, SST600s, or SST1200s
• Communicates wirelessly—no additional wiring to the controller required
• Panel/controller sold separately; sensor kit contains the sensor and bracket

Who is this for? The Rain Bird WR2-RFC wireless rain/freeze sensor kit is ideal for homeowners, landscapers, and property managers who want a straightforward, low-effort way to cut unnecessary irrigation while protecting plants from freezing conditions. It suits anyone who needs easy one-person installation, clear on-device status information, and adjustable thresholds for rainfall and low temperature—especially where running extra irrigation is costly or risky during wet or cold weather.
