How to choose
Detection depth and probes
A probe pair sets how little water triggers an alert. The Aqara sensor detects water as low as 0.5 mm, while the MOCREO sensor detects water as shallow as 0.08 inches. More probes, like the 2 top and 4 bottom probes on the MOCREO and TECKNET sensors, cover drips from above and moisture on the floor. Compare the shallowest detection figure with the spot you plan to watch, such as under a sink or a dishwasher.
Hub, Wi-Fi and alerts
Some sensors send alerts through a hub, while others send them straight to a phone. The Aqara sensor and the SONOFF sensor need a hub, and the Aqara hub links sensors to phone alerts and other Aqara devices. The GoveeLife and MOCREO sensors send SMS, email and app alerts, and the MOCREO hub adds its own alarm. Check the alert path before buying, since a hub-based sensor needs its hub to reach the phone.
Battery life and placement
The GoveeLife, MOCREO and SONOFF sensors run 5 years, while the TECKNET sensor runs more than 2 years on 2 AAA batteries. Place sensors on flat surfaces near dishwashers, sinks, water heaters and washing machines, and keep hub-based sensors within the range their maker gives, such as 10 meters for the Aqara sensor. A cable probe, like the GoveeLife 4.92 ft cable, reaches spots a flat sensor cannot.
