What the differences mean

Cable versus spot

The Eve Water Guard includes a sensing cable. Its write-up describes a 6.5 ft lead that can be extended, so one unit can trace a kitchen or laundry run. The Aeotec Water Leak Sensor has no sensor cable. It only detects water where the puck sits, and that puck is IP20.

Power

The Eve Water Guard is wired. Battery type and battery life are not applicable, and low-battery alerts are not applicable either. The Aeotec Water Leak Sensor is battery only, a CR2 quoted at about one year, and low-battery alerts are not documented.

Radios and platforms

The Eve Water Guard lists Bluetooth and Thread, and it needs a Thread border router. Apple Home and Home Assistant are supported. Matter is marked as coming. Google Home, Alexa and SmartThings are not. The Aeotec Water Leak Sensor needs a Zigbee hub and lists SmartThings and Home Assistant, not Apple Home, Alexa, Google Home or Matter.

Freeze sensing and the siren

The Aeotec Water Leak Sensor lists a temperature sensor, temperature alerts and freeze alerts, and no on-device sound or light. The Eve Water Guard lists a sound and a light, and its write-up cites a 100 dB siren. It does not list a temperature sensor or freeze alerts.
