Aqara Water Leak Sensor T1: 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.
