First Signal L1 Wi-Fi Water Leak and Detector Freezer for $ 64: It works with a large flood sensor, branded first warning, first signal or reside apps and accessories. Sends push notifications and emails to warn a signal related to any leakage and sport. The sensor was relatively slow to be aware of all my tests and push notifications only came when my phone is relevant to Wi-Fi. The cable that felt in the 5-meter water allows you to cover a larger area and I saw that I was aware of faster. The detector connects directly to Wi-Fi, so you need a decent signal. This sensor can also watch the temperature and humidity, but not very accurate (this consistently values ​​temperature and uncharted humidity). The two AA batteries are expected to last for up to two years.

EUFY Safety Water and Freeze the sensor for $ 35: If EUFY security systemThis may be the best water leak detector for you, but it requires a home database 2 or Homebase 3 ($ 150) to join. Uzert is fast and reliable, offers a long distance connection (up to 200 meters) and can notice if the temperature falls below the freezing. With the EUFY security application you can get alerts on your phone and configure the related Homebase to sound alarm, but the detector does not vote. You can watch the battery life in the application. A complete battery lasts up to two years. Unfortunately, it does not show the temperature; Just warns down from the frost.

Rasting Diaqring for $ 12Super affordable, simple designed, this ZigBee detector has a reliable warning during the test. If you have the Ikea Pilling, it’s a good choice IKEA SIVAGEA HUB ($ 109) connect to notifications on your phone. However, if you do not, it costs a lot and is not compatible with other hubs like IKEA Tradfr. There is a signal sound that is as high as 90 decibels, but nearby; It doesn’t go away and I wouldn’t trust him alone. You must submit your own AAA battery and this leak detector is only estimated IP44, so there is a risk of failure if it is immersed.

Switching to $ 19 water leak detector: This rectangular detector caused rapid warnings in all my tests with 100 decibel alarms. With the prongs on the top and bottom, this device is in a hurry to detect water. This is directly connected to Wi-Fi, so you don’t need a center, and it can send push notifications and emails. Unfortunately, Push notifications did not pass when I was outside the house where Wi-Fi had been connected to a mobile network. Clever house The connection is good (Amazon Alexa, Google Assistant and iftt) and this versatile option, you can install automation in the switchbot application, especially if other transition devices. Switchbot says two AAA batteries that are up to two years are good.

Aidot Wines Water Leak Detector S1 Plus (3 packages) for $ 60: Connect to the plug-in hub 2.4-GHz Wi-Fi, three round detectors probably put on leak stains and determined. You can configure it to send emails and SMS messages up to 10 pairs and leaks with Hub. The probes on the bottom of each detector are very far away and 2 millimeters of water gets water before the alarm begins. He could not leave with a constant drop on the top, but it sounded like sounding in the water under the alarm water. The alarm goes up to 100 decibels, but you can make volume and duration pinches for alarms. You can cancel alarms by applying or pressing the buttons in the hub. These detectors take CR2 batteries that are good for a year and have a sign in the application when died. When I remove the battery from one of them, it applied for several hours to update it and show offline. A recent adverse is that HUB is rounded, so it can block adjacent devices. Support for Iftt is detected by a leak, a potentially handy addition to a water parcel or red light.

Agara Water Leak Sensor to $ 19: This zigbee sensor is best used with Apple’s Homekiti and you need Agara Hub (separately sold). The company is double-growing as a center and is a good security camera that offers smart home sensors. These small circular water leak sensors are very low from the ground, so 0.5 mm water at the bottom to trigger an alarm signal. Drips on top will not send them, but an iPhone notification, triggered up to water pools beneath the probes. You can also have an alarming center and have excitement and trigger automation through an excitement and homefit. Sensors take CR2 batteries and last until two years.

Stitching with MonoPrice water leak sensor for $ 25: This affordable water leak detector has a design similar to our best choice. The main body is round with metal legs to reveal the waterfeel and rolled into a bracket for wall installation. Comes with an extension of a coin-sized plug-in plug-in extending to 3.8 feet. Both the basic detector and an extension alarm sounded and sent notifications to my phone when the device is not very high. He receives a single CR2 battery, shows the rest of the application and notifies you when it comes to changing batteries. Unfortunately, the application has been mainly translated. You have to dry the detector to stop the alarm and it took a long time to warn me when offline (strange, offline detector, I had to change it in the application parameters, so I had to change it. You can get this a little cheaper by getting it directly Monoprica.

Leak detectors to prevent

We did not have a great experience with each water leak detector we tested.

Swann Leak Signal Sensor to $ 16: Although this battery is suitable for a water detector (two Aaas), I had a terrible time. Your phone should be in 2.4 GHz Wi-Fi, but therefore made a lot of attempts to contact. Frustrated, you need to remove the farewell panel to reset it because there is no choice. After the sensor came down to my phone a minute, but the Swann application is slow and clunky.
