Insteon
Water Leak Sensor 2852-222
The Insteon Water Leak Sensor (2852-222) is a battery leak detector that fires the moment water bridges its contacts. Local Insteon alerts keep working even when the internet is down.
A battery-powered leak sensor that sits under sinks, water heaters, and washing machines and sends wet and dry alerts. It is RF-only and needs a dual-band Insteon device in range to reach the Hub or PLM. Alerts are local with no cloud, after all-link linking. Sold today as the Insteon Leak Sensor and secondary-market.
