How to choose
Match range to your property
Range decides whether a sensor in a far corner still reaches you. The GoveeLife reaches 1804 feet through walls with Sub-1G wireless tech, and the YoLink reaches 2034 feet in open air over LoRa. The SwitchBot lists a maximum range of 1700 feet. Compare the range figure with the distance from your farthest sensor spot to your phone or hub before you pick one.
Hub, no hub, or standalone alarm
Some sensors need a hub, some join Wi-Fi directly, and one sounds its alarm with no phone link at all. The YoLink kit includes a hub, while the GoveeLife box holds a gateway and the SwitchBot and TECKNET connect straight to 2.4GHz Wi-Fi with no hub. The Geevon sounds its 100 dB alarm on the spot. Pick the setup that matches how you want to hear about a leak.
Alarm volume and battery life
The TECKNET siren reaches 120 dB, the GoveeLife and YoLink reach 105 dB, and the SwitchBot and Geevon reach 100 dB. For battery life, the GoveeLife and YoLink run up to 5 years, the SwitchBot and TECKNET run up to 2 years, and the Geevon runs about 12 months.
