SwitchBot Water Leak Detector

The SwitchBot Water Leak Detector provides early warning of water leaks to help prevent costly damage from flooding, burst pipes, or appliance failures. The sensor detects water contact and immediately triggers a loud local alarm while sending notifications through the SwitchBot app.

Contact probes on the bottom of the device detect water presence within seconds, triggering the built-in 100dB alarm and sending smartphone alerts. Place sensors in vulnerable locations including under water heaters, near washing machines, beneath sinks, in basements, and around HVAC condensate lines.

Bluetooth connectivity enables communication with the SwitchBot app directly or through SwitchBot Hub for extended range and remote notifications. With a hub, receive alerts anywhere and integrate water detection with other SwitchBot devices—automatically shut off a SwitchBot-controlled water valve, trigger cameras to record, or send alerts to all family members.

The compact, low-profile design fits in tight spaces under appliances and in cabinets. Battery operation provides extended monitoring without outlet requirements. The SwitchBot app shows detection history and sensor status. Multiple sensors can monitor different locations with individual naming for quick identification of problem areas. Home Assistant compatible.
