Simplify your life with the power of Smart Watering. No more aimless tinkering with your old irrigation controller. The Blossom Smart Watering Controller automatically programs itself based on real-time local weather data collected from the Internet to create an optimized watering schedule for your yard. This means that on the sunniest, hottest days, Blossom will apply extra water to replenish dry soil. On cooler, less sunny days, Blossom adjusts to irrigate less. If measurable rain is in the weather forecast, Blossom skips watering for that day. The result is an automatically adjusted irrigation plan tailored for your lawn and garden that can be monitored from anywhere at any time from your smartphone or tablet over this Wi-Fi enabled system. Compatible only with locations in the continental United States. Blossom 7 has a known compatibility issue with some newer Comcast / Xfinity XB6 Xfi enabled routers. The specific model numbers included are: -Arris TG3482G (XB6) -Technicolor CGM4140COM (XB6). If you have any of the above routers, please contact us at 1-855-976-5315 or mygro-support@scotts for additional details.
