Aeotec Water Leak Sensor vs Sonoff Zigbee Water Leak Sensor

The Sonoff Zigbee Water Leak Sensor wins overall thanks to its lower price, IP67 waterproofing, a 5-year battery, and broader integrations including Alexa, Google Home and IFTTT. The Aeotec Water Leak Sensor still appeals for its higher owner rating and its added temperature and freeze alerts.

Weatherproofing and integration breadth. The Sonoff Zigbee Water Leak Sensor is rated IP67 and works with Alexa, Google Home and IFTTT, while the Aeotec Water Leak Sensor is only IP20 and limited to SmartThings and Home Assistant, though the Aeotec adds temperature and freeze sensing the Sonoff lacks.

The Sonoff Zigbee Water Leak Sensor is rated for about 5 years on a single CR2477, roughly five times the Aeotec Water Leak Sensor's 1-year CR2 runtime, so it needs far less maintenance.

Only the Aeotec Water Leak Sensor does. It adds a temperature sensor with temperature and freeze alerts, whereas the Sonoff Zigbee Water Leak Sensor is a dedicated leak detector with no temperature sensing.

Buy it if you want the cheaper, IP67-rated sensor with a 5-year battery that pairs with almost any hub, including Alexa, Google Home, SmartThings, Home Assistant and IFTTT.

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