Smart irrigation, simplified

Meet the Rain Bird ST8I-2.0, a smart indoor WiFi sprinkler timer that brings eight controllable zones into the palm of your hand. Designed for homes, it offers convenient remote management, faster app performance, and enhanced reporting so you can tune watering without guessing. The system replaces older models while maintaining reliable performance and compatibility with Amazon Alexa for hands-free convenience.
