## Description

Review: Much much better than I could have hoped for! - This thing is marvelous! We have an HVAC system in the ceiling which caused a leak which damaged the ceiling. That's all fixed now, and we've installed this battery powered, WiFi leak detector's sensor right in the spot where the water will drip. Really simple to install, and we already had a SwitchBot mini-hub. Now, if there's a drip, the alarm will ring a 100DB (loud) , but even more importantly, it will trigger a routine in Alexa! So now, if there's an issue, Alexa will announce throughout the house, what the issue is, and (because we included the directions) instruct whoever's here to shut off that HVAC immediately to prevent further damage! If I had elderly parents living alone, I'd consider putting a few of these in places where there might be an issue with water, such as under their sinks, beneath their dishwasher, on the floor next to the washing machine, etc. Then, if there was a problem, it can also send an email to the responsible family member to alert them! BTW, it's not just 1 sensor. There's a sensor built into the unit, but there's also another one connected by a 2 foot cord. You could put the unit under the kitchen sink AND the sensor on the floor under the dishwasher! Lastly, and this is also interesting, you CAN set the sensor to work to detect when there is NOT water present. Maybe on the edge of an in-ground pool, that if the water gets too low (below the skimmers) that someone would be notified, since running the pools filtration system without sufficient water can result in damage to the equipment. Actually, if you had the pool equipment controlled by Alexa, you could use the "dry" situation to shut down the pool equipment, thereby protecting your equipment automatically!
Review: Great idea for any home! - Works well, loud enough alarm to hear from basement, good price. Great for leak detection anywhere in your home!

## Features

- Real-time Notifications (No Hub Needed): After connecting to Wi-Fi, you will be able to receive real-time email and app notifications remotely when dripping, leaking, or flooding is detected, without the need to purchase an additional hub. Share devices with family, and they can also check home status at any time. (2.4Ghz Wi-fi Only)
- High Sensitivity Drip Alarms: This device is equipped with four sensor probes at the top and bottom, which can detect a low water level of just 0.5mm. If water pipes drip, and your floor is submerged, or gets wet, it will sound an alarm. Water Leak Detector is compact and convenient in size, suitable for placement in laundry rooms, water heaters, dishwashers, sinks, and other places.
- Water Level Detection: Equipped with a 1-meter extended probe, you'll be able to detect changes in water levels of places like swimming pools, bathtubs, and fish tanks. It can also be placed in narrower areas, such as inside refrigerators or washing machines. And is suitable for homes, warehouses, basements, sinks, water heaters, pipelines, and more.
- Includes Loud Alarm Sounds: To help you stay alert, we've included 100dB high pitched alarms, which means even if there is a leak in basements or places a little further away, you'll know in a timely manner. Once discovered, you can manually set it back to mute without worrying about noise issues.
- IP67 Waterproof, Up to 2 Years Battery Life: Water Leak Detector is designed with a fully sealed waterproof shell and can easily handle high humidity working environments. It comes with 2 x AAA batteries and has a battery lifespan of up to 2 years. When battery is low, our app will also send notifications to remind you to replace them in a timely manner.
- Part of SwitchBot Ecosystem, Voice Command Compatible: Use with SwitchBot Plug Mini or Indoor Cam, and remotely turn off electrical equipment or check the condition of your house in case of leakage. It can also support third-party services such as Alexa/Google/Siri/IFTTT/SmartThings.

*by B***. on July 2, 2026*

I am not a techy and was able to set these up with relative ease. They are excellent at detecting water immediately. the problem is getting alerts (not alarms, but texts and emails) either because they have gone off-line or some other reason which I can’t explain. I like that they come with or without a cord that can get tucked in somewhere where the device itself cannot reach. despite the alerts mentioned, I am so happy with them because they bring peace of mind
