Today we are reviewing the Shelly flood sensor. A flood sensor is a sensor to detect water leakage. This may be very useful in situations where water can cause some serious damages to your property. Fortunately Shelly has a very nice WiFi based product on the market to help you solve this issue.
Although this sensor uses Wifi it can still be perfectly used in conjunction with z-wave products. If you are looking for z-wave flood sensors specifically please visit our z-wave flood sensors page.

Let start the review by looking at the features of the Shelly flood. This little sensor has quite a bit of features. packed inside.

Wireless technology and wire free
The Shelly flood sensor is completely wireless. Which means you do not have to connect it to main voltage in order to use it. Which is a good thing considering you will most likely use it in an area where water can flood.

The Shelly flood sensor also has a temperature sensor on board. Which allow you to monitor the temperature in the room where you have place the Shelly flood.

Battery life
According to Shelly the battery of this sensor can last up to 18 months. We at ZwaveGuide have not yet tested this. But 18 months on a 3.3v is quite impressive!

Setup and installation of the sensor

The setup of the sensor is pretty straight forward. You just twist the top of the flood sensor and press the setup button inside. This will put the sensor into setup mode for 3 minutes. You can then use the Shelly app and follow the instructions to connect it to your Shelly account.

There is not a lot we can say about actually using the sensor. That means the sensor should work for you instead. We have tested the flood sensor using some water in the video below:
