Winner

Aqara Water Leak Sensor T1

C$36.99

Buy on Amazon Canada

The Aqara Water Leak Sensor T1 wins this water leak sensor matchup on price, an IP67 waterproof rating, a longer 2-year battery, and the widest integrations. Through an Aqara Hub it reaches Alexa, Google Home, Apple HomeKit, and Matter, plus IFTTT and Home Assistant, well beyond the Aeotec's SmartThings-and-Home-Assistant scope. The Aeotec Water Leak Sensor still counters where it counts for pipe protection: it adds a temperature sensor with temperature and freeze alerts that the leak-only Aqara Water Leak Sensor T1 does not offer. Both are Zigbee sensors that require a hub and lack an on-device siren. Buy the Aqara Water Leak Sensor T1 for a cheaper, waterproof, longer-lasting sensor with the broadest ecosystem reach; choose the Aeotec Water Leak Sensor if built-in freeze and temperature monitoring in a SmartThings or Home Assistant setup matters more.
