Govee WiFi Water Leak Detector 3-Pack (H5040 Gateway + H5054 Sensors)

Three battery leak sensors that shout — and message your phone — before a drip becomes damage.

This Govee kit pairs three battery-powered H5054 water sensors with an H5040 Wi-Fi gateway that plugs in anywhere in the home. When a sensor's probes touch water — under the kitchen sink, behind the dishwasher or by the water heater — it sounds a 100dB adjustable alarm locally and pushes an alert to the Govee app and your email, with each sensor nameable by location so you know exactly where the leak is. The gateway supports up to 20 sensors on 2.4GHz Wi-Fi, so the system can grow room by room.

What we like

Instant app push and email alerts plus a loud 100dB on-site alarm — works even if you're away
Sensors are small, battery powered and need no wiring or hub subscription
Gateway supports up to 20 named sensors, so you can expand coverage over time
Adjustable alarm volume with mute, and low-battery reminders in the app

Good to know

Gateway works on 2.4GHz Wi-Fi only, and sensors must stay within about 196 ft of it
Sensors detect water at floor level only — they can't catch a slow drip inside a wall or a pipe leak that never pools beneath them
Gateway pairs only with Govee H5054 sensors, not other Govee or third-party sensors

Who should consider it

Homeowners who want early warning under the kitchen sink, by the dishwasher, water heater or washing machine — especially in homes that sit empty during the workday or vacations.

Who should skip it

Skip it if you want automatic water shut-off (this only alerts — pair it with a separate smart shut-off valve for that), or if your home has no reliable 2.4GHz Wi-Fi near the gateway spot.
