Aqara Water Leak Sensor: Capabilities And Limitations
Based on listed specifications, not hands-on testing. Manufacturer sources are linked where checked.
What it offers
A Home Assistant integration is listed, providing an integration path to verify for the exact model. Check the exact integration and firmware. A catalog integration label does not establish local control, official support or available entities.
View Home Assistant details →Water-leak alerts are recorded as a supported monitoring event. Verify the notification path and any controller dependency. An alert alone does not close a water valve. When the water level reaches up to 0.5mm, the Water Leak Sensor will trigger the Hub to sound an alarm and send a notification to your phone.
View Water Leak Alerts details →Low-battery alerts are recorded, providing a maintenance notification to verify in the chosen platform. Check the alert destination and how disconnected-device status is handled.

What to consider
A sensing cable is listed as unavailable; plan placement around the supported sensing points.
View Sensor Cable details →An on-device audible alert is listed as unavailable; verify the remote alert path.

Questions About Aqara Water Leak Sensor
Does Aqara Water Leak Sensor support Matter?
Matter is listed as “Aqara Hub required”. The stated condition applies to this feature. Verify the exact device type, firmware and features exposed in your chosen platform. Matter support is not proof of feature parity. Aqara Hub M2 and M3 firmware added leak sensors to their Matter bridge, so the sensor reaches Matter through one of those hubs.
View Matter specifications →Does Aqara Water Leak Sensor work with Apple Home?
Apple Home is listed as “Aqara Hub required”. The stated condition applies to this feature. Check the model, firmware, exposed controls and any additional hardware requirements.
View Apple Home specifications →Does Aqara Water Leak Sensor support Zigbee?
Zigbee is listed as “Zigbee Hub required”. The stated condition applies to this feature. Check the device role and compatible coordinator. Zigbee connectivity alone does not establish compatibility with every hub.
View Zigbee specifications →Does Aqara Water Leak Sensor support Thread connectivity?
No, according to the listed specifications. Thread connectivity alone does not establish Matter support or a border-router role. Check those requirements separately.
View Thread specifications →Does Aqara Water Leak Sensor work with Home Assistant?
Yes, according to the listed specifications. Check the exact integration and firmware. A catalog integration label does not establish local control, official support or available entities.
