WeatherMatic SmartLine Weather Stations

SLW15 is built to last
SLW15 uses 2 AA lithium batteries with a 15-year shelf life to ensure 10-years of reliable operation without ever changing the battery. The elimination of a single service call alone justifies the upgrade from a wireless sensor with poor battery life to the SLW15 weather station.
SLW15 consistently delivers smart evapotranspiration watering schedules where wiring is impractical and satellites/cell towers cannot reliably reach
With a range of 600 feet line of site, SLW15 is the ultimate tool for retrofitting any of the 30 million+ existing irrigated properties wanting to: save 20 to 50% in water usage, grow healthier plants, virtually eliminate run off, and put an end to watering worries.
