How to choose
Alarm volume and range
Alarm volume, measured in decibels, sets how loud the alarm sounds, and range sets how far the signal reaches. The GoveeLife and YoLink sound at 105 dB, and the EZ2LOCATE and Topvico sound at 120 dB. The GoveeLife range is 1804 feet, and the YoLink range is 2034 feet. Compare the volume with the distance from the detector to the rooms you use, and check the range against the size of the property.
App, hub and standalone detectors
Some detectors send alerts through an app, some need a hub, and some sound a local alarm with no app or hub. The GoveeLife sends SMS, Email and APP notifications through a gateway, the YoLink needs a hub for full functionality, and the EZ2LOCATE sounds a local alarm with no Wi-Fi, app, hub or subscription. Check what your home already has before you choose, and check whether a hub is included in the pack.
Placement and upkeep
Place a detector under a sink, near a water heater or near a sump pump. Dry the sensor board after activation, as the Topvico board is ready for use again after drying. The EZ2LOCATE gives a low battery alert every 60 seconds, so check the battery when you hear that alert.
