How to choose
Alarm volume and detection depth
Alarm volume sets how easy an alert is to hear. The X-Sense sounds dual 120 dB alarms from the sensor and the base station, the GoveeLife and the YoLink sound 105 dB alarms, the SwitchBot sounds a 100 dB alarm, and the Tapo sounds a 90 dB adjustable alarm. Detection depth sets how shallow a pool can be: the X-Sense detects water as low as 0.4 mm, and the SwitchBot detects a low water level of 0.5 mm.
Hub, gateway and Wi-Fi
A base, gateway or hub links sensors to your phone, while a no-hub sensor connects straight to Wi-Fi. The X-Sense uses a base station, the GoveeLife uses a gateway, and the YoLink uses a hub, while the SwitchBot needs no hub and the Tapo requires a Tapo Hub. The X-Sense, the GoveeLife gateway and the SwitchBot use 2.4 GHz Wi-Fi, so check that your network matches before you buy.
Battery life and placement
The GoveeLife battery lasts 5 years, the YoLink battery lasts up to 5 years, the Tapo battery lasts up to 3 years, and the SwitchBot battery lasts up to 2 years. Place a sensor beside a water heater, a washing machine, a dishwasher or a sink, where a leak would first pool on the floor.
