Two similarly sized leak pucks, one real difference: the Heiman Smart Water Leakage Sensor edges out the Aqara Water Leak Sensor in this water leak sensor comparison mainly on battery life and having a built-in alarm sound and light, since both share the same IP67 weather resistance and a one-year warranty. The Aqara Water Leak Sensor holds its own on ecosystem reach instead, it connects to Apple HomeKit through an Aqara Hub and adds IFTTT support, giving it a wider spread of integrations than the Heiman Smart Water Leakage Sensor, whose SmartThings support is only partial. Neither model senses temperature or offers a tamper alert, and both need extra hardware for full smart functionality, a Zigbee coordinator for Aqara, a WiFi network and gateway for Heiman's remote alerts. Buyers who want a physical, audible alarm and a longer-lasting battery should pick the Heiman Smart Water Leakage Sensor, while anyone building around Apple HomeKit or IFTTT automations gets more mileage from the Aqara Water Leak Sensor.
