Other leak detectors we like

First Warning L1 Wi-FI Water Leak and Frozen Detector in $ 62: It works with large flood sensors, branded first alert, first alert or recessive apps and accessories. It sends Push notifications and email to inform you of any leaks and plays 100 dysbon alarms that you can stop from the side button. The sensor was relatively slow to alert all my tests, and push reports came only when my phone was connected to Wi -Fi. The 5 -foot waters sensing cable allows you to cover a very large area, and I found out that it has been alerted rapidly. The detector is directly connected to Wi -Fi, so you need a good signal. It can also track the sensor temperature and humidity, but not very accurate (it permanently enhances the temperature and considered moisture less). It is believed that the two batteries provided by AA will continue for two years.

Switch boot water leak detector in $ 18: This rectangular detector has mobilized Swift Alerts with 100-dasble alarm in all my tests. With the top and bottom proongs, this device was in a hurry to detect. It is directly connected to Wi -Fi, so you do not need a center, and it can send push notifications and email, though you have to configure them in the app. Unfortunately, when I was out of the house, there were no push reports, which were linked to the cellular network instead of Wi -Fi. Smart Home Connectivity is good (Amazon Alexa, Google Assistant, and IFTTT), and you can configure automation in the switchboat app, which makes it a versatile option, especially if you have a switch There are other boot devices. The switch boot says the two AAA batteries provided are good for two years.

Advocate Water Lake Dettor S1 Plus (3 Pack) $ 60: Connect the plugin hub to your 2.4 GHz Wi -Fi, possibly place three circular detectors in leaks, and you are ready. You can make 10 detectors with the hub and create it to send emails and SMS messages to the upper part of the app notifications when there is leakage. The investigations below each detector are far away, and the alarm requires 2 mm water before it is mobilized. It failed to go with a steady tip on the top, but the alarm seemed as soon as the water came down. The alarm goes up to 100 decibile, but I like you can adapt the volume and duration for the alarm. You can cancel alarms through the app or press the button on the hub. These detectors take CR2 batteries that are good for a year, and when they die, the app indicates it. When I removed the battery from any of them, it took the app a few hours to update it and show it as an offline. One last negative aspect is that the center is circular, so it can stop adjacent shops. Support for IFTTT is a potentially easy addition that can trigger water closures or light red red red when it is detected leakage.

Aqara Water Lake sensor for $ 19: This zagby sensor is best used with Apple’s home kit, and you need akara center (Sold separately) The company creates a good security camera that doubles as a center and offers a whole range of smart home sensors. These small circular water leak sensors are very low on the ground, so the bottom is enough to mobilize 0.5 mm water alarm. The dripping above will not remove them, but whenever there is an investigation, the report of an iPhone is mobilized with the water pool. You can also play alarm and trigger automation through home kit to your attached hub. Sensors take CR2 batteries and can stay for two years.

Sewing through Monopares Water Lake Sensor in Mon 25: This affordable water leak detector is a design that is similar to our selection. The main body is round, with metal feet to detect water ponds, and it slots into a growing wall of the wall. It comes with a coin -shaped plug -in extension, which extends to 3.8 feet. Both the central detector and the extension were in a hurry to send the alarm and send notifications to my phone when wet (though the on -device alarm is not high). It takes the same CR2 battery, shows the remaining strength in the app, and when it comes time to replace the batteries, alert you. Unfortunately, the app has been translated as basic and poorly translated, you have to dry the detector to stop the alarm, and it took a long time to warn me when it went offline (the odd thing is that offline The detector is togelled by default in the app settings, so I had to turn it on). Buying directly you can get it a bit cheap Monoprice.

Lake detectors to escape

We had no good experience with every leak detector we experienced.

Swan Lake Alert Sensor for $ 12: Although this battery -powered water detection (two AAAS) is affordable, I have had a terrible time to set it up. Your phone should be 2.4 GHz on Wi -Fi, but nevertheless he made numerous efforts to connect me. With frustration, you have to remove the screw panel to reset it because there is no option in the app. A minute after the sensor was soaked, a warning over my phone, but the Swan app is slow and down.
