Weathermatic SLW5 Wireless Weather Station delivers on-site weather sensing and SmartLine® compatibility to automatically adjust irrigation run times based on real-time conditions. Designed for outdoor use, the SLW5 combines rain and freeze detection with evapotranspiration (ET)-based adjustments to reduce water waste and lower operating costs for residential and light-commercial systems.

  • SmartLine® compatible — ships with the SLHUB‑RF‑5 wireless hub for easy setup and pre-paired communication.
  • Adjustable rain shut-off from 1/8″ to 1″ (3–25 mm) with an extended rain-delay feature (48‑hour default; adjustable 0–99 hours).
  • Freeze shut-off activates at 37°F (3.0°C) and automatically resumes irrigation when temperatures rise.
  • 900 MHz bi‑directional wireless communication with up to 1,500 ft (457 m) line-of-sight range; obstacles may reduce effective range.
  • Operates on two AAA lithium batteries (supplied) with remote battery diagnostics and up to 10-year battery life under normal conditions.
  • Protective white solar shields and an adjustable aluminum mounting arm for gutter or wall installation provide accurate temperature readings and low maintenance.
  • On-board diagnostics report battery and communication status to the SmartLine controller to simplify troubleshooting.

Durable and easy to install, the SLW5 is ideal for contractors and landscape professionals who want reliable, low-maintenance weather-based irrigation control. Refer to the included installation guide for setup steps, diagnostics, and warranty information.
