Share the devices with your family so they can check the status of your home at any time. (only 2.4 GHz Wi-Fi & BLE) - Highly sensitive drip alarm: the water detector is equipped with four sensor probes on the top and bottom, which can detect low water levels of only 0.5 mm.

The water leak detector has a compact and practical design and can be installed in laundry rooms, instantaneous water heaters, dishwashers, sinks and other places. - With loud alarm tones: To ensure you hear the alarm loud and clearly in emergency situations, we have built in a 100 dB loud alarm. Once you have detected the emergency center, the alarm can be easily switched off to solve the problem in peace. - IP67 waterproof, up to 18 months battery life: The water detector is equipped with a fully sealed, waterproof housing and can be easily used in high humidity environments. It comes with 2 x AAA batteries and has a battery life of up to 18 months.

This delay is by design for power efficiency. Use a Hub near the detector for faster alerts. **Q: How to set up SwitchBot Water Leak Detector email notifications?** A: Update the SwitchBot App, add the detector, then go to Profile > Preferences > Email Notifications > Important Device Notifications. Select your detector, enable "Email Alerts," and add your email.
