How to choose
Range for a basement
Range is how far a sensor signal travels to its hub or to Wi-Fi. The GoveeLife reaches 1804 feet, the MOCREO reaches 2000ft, and the SwitchBot connects straight to 2.4GHz Wi-Fi with no hub. Compare the range figure with the distance from your basement to your router, and place the hub where the signal stays strong.
Alarm volume and alerts
Alarm volume is the loudness of the local siren, while app, SMS, and email alerts reach you away from home. The GoveeLife and the MOCREO sound a 105 dB alarm, and the SwitchBot and the winees sound a 100 dB alarm. The GoveeLife, the winees, and the MOCREO send SMS, email, and app alerts. Check how you want to be reached, and set the volume level that fits the room.
Placement and battery life
Place a sensor where water first collects, such as near a water heater, a sump pump, or under a sink, and keep the probe in contact with the floor. The X-Sense fits under appliances and behind toilets, and the MOCREO fits under low-clearance appliances. Battery life differs by model: the GoveeLife lasts 5 years and the SwitchBot lasts up to 2 years. Note the battery figure before you buy, so a dead sensor does not go unnoticed.
