Meross Smart Water Sensor Alarm 3 Pack, WiFi Water Leak Detector Support Apple HomeKit, SmartThings, IP67 Waterproof with App Alerts, Alarm, 100M Range for Home Basement Kitchen (Meross Hub Included) - desertcart.com

Review: Easy to use. Works well. - These water sensors were easy to set up and work well at detecting leaks. As long as you have Wi-Fi, the detectors will alert you the second that they sent water touching them. The alert is pushed out to your cell phone and can help you prevent extensive damage to your property.
Review: An ounce of prevention… - Well I should have bought these before I had the hot water heater leak through the utility room and through the garage. I have a few Meross items that I’m a fan of and with the price point on this and figuring I needed it, I decided to buy one. It integrates well, easy to set up, works well with HomeKit. Battery is easily replaceable which beats buying something to throw it out when it’s done. Now if I could just get the cat to stop playing with it and leave it near the hot water heater.

## Features

- Remote Monitoring & Automation: Compatible with Apple HomeKit (with HomeKit bridge, home WiFi stay online), and SmartThings, easy to set up, monitor water leaks remotely. Set triggers to control other Meross devices in the Meross app. e.g. once a leak is detected, the sensor will trigger Meross plug to turn off fish tank water pump.
- IP67 Waterproof: Fully sealed IP67 waterproof and dustproof design, works well in high humidity environment, no rust, no short circuit, high sensitivity, no false alarm. Made of advanced nickel-plated carbon steel material, the water level detector alerts and stays in place when the water level rises beyond.
- Real-time Alert & Precise Detection: Equipped with sensitive probes, the water level threshold is Only 0.5mm. Water leakage activates a real-time local audible and visual alarm, and phone app notifications.
- 100M/328ft Transmission Distance: With SubG Wireless technology, 3X stronger and more stable signal transmission than WiFi and ZigBee/Thread Range, the sensor can effectively monitor water leakage even in the basement.
- Superb Versatility: One hub can control up to 16 Meross sensors; low-power consumption; check data anytime or export them out via the free Meross app.

### ⭐⭐⭐⭐⭐ Easy to use. Works well.

These water sensors were easy to set up and work well at detecting leaks. As long as you have Wi-Fi, the detectors will alert you the second that they sent water touching them. The alert is pushed out to your cell phone and can help you prevent extensive damage to your property.

### ⭐⭐⭐⭐⭐ An ounce of prevention…
*by J***F on October 6, 2025*

Well I should have bought these before I had the hot water heater leak through the utility room and through the garage. I have a few Meross items that I’m a fan of and with the price point on this and figuring I needed it, I decided to buy one. It integrates well, easy to set up, works well with HomeKit.

### ⭐⭐⭐⭐ Worked great if within range
*by R***E on December 28, 2023*

The items work fine but I found the range to be quite limited. I could not get a reliable signal in my home. I have a second smaller building and these work great there. Setup was easy and easily connected to Home Kit. So read the instructions about range and if that works for you these are fine. I bought a set from another manufacturer for my home and it worked fine but was more expensive. I rated it 4 stars simply because of the range, perhaps I should have been more careful about reading all the information.
