How to choose
Alarms and alerts on a smart water leak detector
Alarms decide how fast you hear about a leak. The TECKNET sounds a 120 dB alarm, the GoveeLife and the YoLink sound 105 dB alarms, and the SwitchBot sounds a 100 dB alarm. For alerts, the GoveeLife sends SMS, email and app push alerts, the YoLink sends app, email and SMS alerts, and the TECKNET and the SwitchBot send app alerts. Match alarm volume and alert types to how far sensors sit from living spaces.
Range, hubs and power
Range decides how far sensors sit from the hub or router. The GoveeLife reaches up to 1804 feet through 5 walls, and the YoLink reaches up to 2,034 feet in open air with LoRa. For hubs, the GoveeLife gateway and the YoLink hub come in the box, while the TECKNET and the SwitchBot need no hub. For power, the GoveeLife battery lasts 5 years, the YoLink sensors run up to 5 years, and the TECKNET and the SwitchBot run up to 2 years.
Shutoff and placement
Placement decides which detector fits each spot. The TECKNET and the SwitchBot sensors sit near water heaters, sinks and dishwashers, and the GoveeLife suits basements and kitchens, while the Moen installs on the main water line for whole-home coverage. The Moen shuts off water automatically, and the YoLink sensors trigger sirens or shutoff valves without internet. Place point sensors near appliances and the Moen on the main line.
