Aeotec Water Leak Sensor vs Eufy Water and Freeze Sensor

The Eufy Water and Freeze Sensor, for a home with a Eufy HomeBase. It is the lower priced of the two, sealed to IP65 and rated for 2 years on a CR123 battery. The Aeotec Water Leak Sensor is the better pick for a Zigbee home on SmartThings or Home Assistant, where it adds automations and general temperature alerts.

Yes. The Eufy Water and Freeze Sensor has no Wi-Fi of its own and connects to a Eufy HomeBase, which puts it online. The Aeotec Water Leak Sensor has the same kind of dependency on a Zigbee hub instead.

No. Neither the Aeotec Water Leak Sensor nor the Eufy Water and Freeze Sensor works with Alexa, Google Home, Apple Home or Matter. The Aeotec works with SmartThings and Home Assistant; the Eufy stays in the Eufy app, with Home Assistant reachable only through a community integration.

It is rated IP65, so the Eufy Water and Freeze Sensor can sit on a wet floor. The Aeotec Water Leak Sensor is rated IP20 and is meant to be placed near a leak rather than in standing water.

SmartThings and Home Assistant users with a Zigbee hub who want leak, temperature and freeze alerts in one small sensor and plan to automate a shutoff valve with it.

Eufy security owners with a HomeBase who want leak and freeze warnings in the same app as their cameras, from a sensor that tolerates a wet floor and needs a new battery only every couple of years.
