Garden at Home Rain Bird WR2-RC A55300 Wireless Rain Sensor Combo — Battery-powered with Freeze Detection and Adjustable Rain Thre

Modern irrigation needs simple, reliable sensors that prevent unnecessary watering and reduce system wear. The Rain Bird WR2-RC A55300, offered by Garden at Home, pairs an easy-to-mount wireless sensor with compatible controller communication to halt scheduled irrigation during rain or freezing conditions. Designed for fast one-person installation and clear signal feedback, it helps contractors and homeowners cut water use while keeping plants healthy.

How does this sensor stop watering when it rains or freezes?

The WR2-RC detects rainfall and freezing temperatures and sends a wireless signal to a compatible Rain Bird controller to suspend irrigation cycles. You can set the rainfall threshold so the system only skips cycles once a chosen amount of rain accumulates. Freeze detection prevents watering when temperatures approach freezing, protecting plants and irrigation hardware.

• Adjustable rainfall set points to match local climate and plant needs
• Integrated freeze detection that triggers controller pause
• Wireless communication with clear signal strength indicators

How easy is it to install and set up the WR2-RC?

Installation is optimized for a single installer: a versatile mounting bracket attaches to gutters or any vertical surface, and the sensor runs on battery power so no wiring is required. The WR2-RC displays signal strength both on the sensor and at the controller interface, simplifying placement for reliable reception. Programming takes only minutes using the controller menus.

• One-person mounting bracket for gutters, fences, or walls
• No hardwiring—battery-powered for fast deployment
• On-device and controller signal strength readouts for correct placement

What performance and water savings can I expect?

By preventing irrigation during rain events and near-freezing conditions, the sensor reduces wasted water and avoids overwatering stress on plants. Rain Bird estimates up to 35% water savings depending on local rainfall and schedule habits. The WR2-RC’s dependable signal and configurable thresholds ensure the controller responds only when appropriate.

• Configurable rain thresholds for tailored shutoff behavior
• Potential water savings up to 35% with proper setup
