OtO Inc. is a Toronto-based company specializing in smart lawn care solutions. Founded in 2019, it developed the OtO Smart Sprinkler, a weather-responsive, app-controlled device designed to automate hose-end watering efficiently. The system helps homeowners save water and time while maintaining healthy, well-irrigated lawns. OtO’s innovative technology has gained recognition in the smart home industry, making lawn care simpler and more convenient. In 2025, the company was acquired by Rain Bird Corporation but continues to operate under its own brand, focusing on making smart, automated irrigation accessible to a wider audience through both retail and online channels. The company’s mission is to combine technology with sustainable lawn care.
