The Buoy Water Controller was a Resideo leak detection and water monitoring product, but it has been discontinued because it did not meet the company’s quality and scalability standards. Resideo stated that it planned to introduce a next-generation leak detection and protection product. Support for the Buoy app and data service ended on March 31, 2021; after that date, the controller no longer connected to Wi-Fi, and users could no longer access the app or information such as water usage data and leak notifications. Resideo indicated that the discontinuation would not affect a home’s plumbing system.
