Heiman Smart Water Leakage Sensor vs Sonoff Zigbee Water Leak Sensor

The Heiman Smart Water Leakage Sensor comes out ahead overall, with a lower price, a higher owner rating, and a built-in on-device alarm sound and light. The Sonoff Zigbee Water Leak Sensor answers with a much wider set of integrations, including Google Home, Alexa, Samsung SmartThings and IFTTT.

Local alerting versus platform reach. The Heiman Smart Water Leakage Sensor sounds its own alarm and flashes a light the moment it detects water, while the Sonoff Zigbee Water Leak Sensor has no on-device alert sound or light at all and depends entirely on your Zigbee hub for notifications.

No, it has no on-device alert sound or light, so notifications rely completely on your Zigbee hub and its automations. The Heiman Smart Water Leakage Sensor includes both a local alarm sound and an alert light.

The Sonoff Zigbee Water Leak Sensor, by a clear margin, it works with Google Home, Alexa, Samsung SmartThings, Home Assistant and IFTTT. The Heiman Smart Water Leakage Sensor only reaches Home Assistant plus partial Samsung SmartThings support.

Buyers who want a cheaper sensor with its own audible local alarm and light, and who don't need it tied into a wide range of third-party smart home platforms.

Buyers already running a Zigbee hub who want the widest possible platform reach, Google Home, Alexa, SmartThings, Home Assistant and IFTTT, and who don't mind relying on their hub rather than an on-device alarm for alerts.
