Anker eufy Water and Freeze Sensor

With the eufy Water and Freeze Sensor, you won't have to worry about damage from water or temperatures that are too low in your home anymore. You can connect the sensor to your smartphone via a HomeBase 2 or 3. You'll get a notification on it when the sensor detects water or when the temperature near the sensor drops below 0 degrees Celsius. Because the sensor runs on a battery, you can easily place it anywhere you want within 200 meters of the HomeBase. For example, under the sink in the bathroom or in a kitchen cabinet. The CR123 battery is included and lasts about 2 years.
