Shelly water leak detection sensor, wireless, application control, Home Assistant compatible

Shelly Flood, introduced in September 2019, is the new Shelly WiFi access flood / leak sensor. Due to the low consumption, the battery powered device can work for more than 1 year or according to the factory manual even 18 months.
By placing the device under a water tap, washing machine or sink, when the sensor detects water leaks (for example, due to a broken pipe, broken valves, faulty hot water radiator), the sensor is activated and sends an alarm to the Shelly app . By connecting the Shelly Flood with a Shelly 1 relay, you can even control an electric water valve. The flood sensor has a built-in temperature sensor so it can measure the temperature of the floor if you have underfloor heating.
