8 Best water losses detectors (2025), tested and revised

Other losses detectors we like

First warning L1 L1 Wi-Fi water loss and freezing detector for $ 64: This great flood sensor, the first notice with brand, works with apps and accessories for the first warning or resideo. Send push and email notifications to notify any loss and show off an alarm of 100 decibels that you can stop with the side button. The sensor was relatively slow to warn in all my tests and push notifications only came when my phone was connected to Wi-Fi. The 5 -foot water detection cable allows you to cover a much larger area and I found it notified faster. The detector connects directly to Wi-Fi, so a decent signal is required. This sensor can also trace the temperature and humidity, but not very accurately (it has constantly overrated the temperature and undervalued humidity). The two AA batteries provided should last up to two years.

EUFY Security Water and Freeze Sensor for $ 35: If you have an EUFY safety system, this could be the best detector of water leaks for you, but requires a home 2 o Homebase 3 ($ 150) To connect to. He proved to be rapid and reliable from the notice, offers long -haul connectivity (up to 200 meters) and can warn you if the temperature drops below freezing. Receive notices on the phone via the EUFY Security app and you can configure the home basis connected to playing an alarm, but the detector does not emit any sound. You can keep track of the battery life in the app. A complete battery lasts up to two years. Unfortunately, it does not show the temperature; Simply approaches below zero.

Ikea Badding for $ 12: Super convenient, with a simple design, this zigbee detector has notified reliably during the tests. Ikea Badring is a good choice if you already have a Ikea directs Hub ($ 109) To connect for notifications on the phone. But if you don’t do it, it works quite expensive, and it is not compatible with other hubs, such as Ikea Tradfri. It has an alert sound that reaches up to 90 decibels, but only nearby; He does not carry away and I would not rely on my own. It is necessary to provide your AAA battery and this loss detector is classified only IP44, so there is a risk of malfunction if it is immersed.

Switchbot water leak detector for $ 19: This rectangular detector has triggered rapid notices in all my tests with an alarm of 100 decibels. With the poles on top and below, this device was quick to detect the water. It connects directly to the Wi-Fi, so an hub is not necessary and can send notifications and emails push, even if you need to set them in the app. Unfortunately, the push notifications did not arrive when I was out of the house, connected to a cellular network instead of wi-fi. Smart Home connectivity is good (Amazon Alexa, Google Assistant and IFTTT) and you can set automation in the Switchbot app, which makes this option versatile, in particular if you have other switchbot devices. Switchbot says that the two AAA batteries provided are good for a maximum of two years.

Aidot Winees Deatte Deatte Deatta Detero S1 Plus (3 package) for $ 60: Connect the plug-in hub to the 2.4 GHz Wi-Fi, place the three circular detectors in probable loss points and set out. It is possible to combine up to 10 with the hub and configure it to send and -mail and SMS messages at the top of the notifications of the app when there is a loss. The probes on the lower part of each detector are quite distant and it takes 2 millimeters of water before the alarm is activated. He was unable to overcome himself with a constant dripping at the top, but the alarm played as soon as the water grouped underneath. The alarm goes up to 100 decibels, but I like that you can change the volume and duration for alarms. You can cancel the alarms via the app or by pressing the buttons on the hub. These detectors take CR2 batteries that are good for a year and there is an indication in the app when they die. When I removed a battery from one of them, the app took a few hours to update it and show it as offline. A last negative aspect is that the hub is circular, so it can block adjacent stores. Support for IFTTT is an extra potentially useful that could trigger water off or a light to flash in red when a loss is detected.

Aqara water leak sensor for $ 19: This zigbee sensor is better used with Apple’s homekit and you need an Aqara hub (sold separately). The company is a good security camera that also acts as a hub and offers a complete range of intelligent home sensors. These small circular water loss sensors are very low on the ground, so only 0.5 mm of water below are sufficient to trigger an alarm. The dripping at the top will not make them run away, but an iPhone notification is activated as soon as the water pools under the probes. It is also possible that your connected hub replied an alarm and activate automation via homekit. The sensors take CR2 batteries and can last up to two years.

Monoplice water leak sensor for $ 25: This detector of water losses at affordable prices has a design similar to our best choice. The main body is acting comes with a plug-in extension of the size of a coin that extends up to 3.8 feet. Both the main detector and the extension have been quick to play the alarm and to send notifications to my phone when they are wet (even if the alarm on the device is not very strong). It takes a single CR2 battery, displays the remaining power in the app and warns you when it’s time to change the batteries. Unfortunately, the app is fundamental and scarcely translated. You have to dry the detector to stop the alarm and it took too long to warn me when it went offline (strangely, the offline detector is activated by default in the app settings, so I had to turn it on). You can get it a little cheaper by buying directly from Single -seater.

Losses detectors to avoid

We did not have a great experience with any detector of water losses that we tested.

SWANN losses notice sensor for $ 16: While this battery -powered water detector (two AAA) is convenient, I had a lot of fun preparing it. Your phone must be on 2.4 GHz Wi-Fi, but in this case also it took me more attempts to connect. Frustrating, it is necessary to remove the screw panel to restore it, because there is no option in the app. The notices arrived at my phone about a minute after immersing the sensor, but the Swann app is slow and clumsy.
