Aeotec Water Leak Sensor vs Aqara Water Leak Sensor

The Aqara Water Leak Sensor wins overall on price, an IP67 waterproof rating, a longer 2-year battery, and wider integrations. The Aeotec Water Leak Sensor is still worth it for its higher owner rating and its added temperature and freeze alerts.

Sensing scope and weatherproofing. The Aeotec adds temperature and freeze alerts on top of leak detection, while the leak-only Aqara Water Leak Sensor carries an IP67 rating for direct water contact and the Aeotec is only rated IP20.

The Aqara Water Leak Sensor is rated IP67, built to handle direct water contact and light submersion. The Aeotec Water Leak Sensor is rated IP20, so it should be placed to detect nearby leaks rather than exposed to splashing.

Only the Aeotec Water Leak Sensor does. It includes a temperature sensor with temperature and freeze alerts, whereas the Aqara Water Leak Sensor is a dedicated leak-and-battery-alert device with no temperature sensing.

Buy it if you want the cheaper, waterproof (IP67) sensor with a longer 2-year battery and HomeKit, IFTTT, or Home Assistant support through an Aqara Hub.

Choose it if you run SmartThings or Home Assistant and want a higher-rated sensor that also flags temperature and freezing conditions near pipes, not just leaks.
