Escape of water damage is one of the most common types of domestic property damage claims—more than fire or theft. These aqueous accidents of course can stem from floods and storms, but most involve burst washing machine hoses, bathroom or roof leaks, and general toilet, water tank, hot water tank or refrigerator piping malfunctions. The result? Water damage that can run you in the thousands of pounds.
Sure, you can place dumb water detectors that emit an alarm when pools appear. But these detectors are only effective if you’re home to hear the alarm, and can take the action quickly.
If you’re often out of the house, on the road, simply at work, or own a second home, you want a Smart WiFi leak detector. Unlike an alarm no one may hear, a Smart WiFi leak detector can transmit an emergency alert to your smartphone and help you to prevent an unwanted aquatic event.
Samotech Smart WiFi water leak detector is connected to your Internet at home and accurately monitors for any accumulated water around its sensor. It is small enough to be hidden under the sink or any other place you want to monitor. When the sensor detects water the device sends an alert to your smartphone making you aware of the potential issue and helps to avoid a bigger problem.

    Really like this product, the phone notification and low price makes it a must buy

    Bought this leak detector due previous leaks in the bathroom. Tested it and works fine one installed and when water reaches the 2 contacts. Installation was not straight forward and had to try a couple of times before succeeding as the blue flashing light timed out. One thing missing is it has no audible warning on the detector which would have been a nice addition. At present the only warning is through a notification on the App which may not alert if phone is on silent. I have also managed to get my smart lights to flash by linking via IFTTT.

    Installed under a bath, the cable is long enough to attach the unit itself in a reachable place.

    I bought two of these after the more expensive Honeywell Lyric failed to connect to the network.This samotech device arrives in a simple white box and the battery is preinstalled. The wifi and app pairing instructions are printed on the box. You download the smart life app (ios and android) and run a simple installation process registering the device with their cloud and your wifi access point (2.4G only it says in the help file of the app).Once registered I tested it in a tiny amount of water and within seconds I received a sound alert on my phone. You can also set up the app on multiple phones e.g. your spouse and both get the alert. Brilliant. Easy, cheap and works. Can’t speak for how long it will work but the day 1 impression is great.
