Catch the leak before it becomes a flood.
A discreet puck that spots water the moment it pools — then sounds the alarm, pings your phone, and can even shut the water off.

Sounds the alarm at the first 0.5 mm
Sit it anywhere water shouldn't be — under the sink, behind the washer, beside the water heater. The moment water reaches 0.5 mm, the T1 triggers your Aqara hub to sound its alarm and pushes a notification straight to your phone, whether you're home or away.
- Leak detected — the conductive base reacts to standing water in seconds
- App notification — an instant push alert, at home or out
- Hub alarm — your Aqara hub sounds a loud local siren
IP67-sealed, and made to last
Dust and splashes are no problem. The T1 carries a full IP67 dust- and water-resistance rating, so it keeps working in the humid, damp corners where leaks actually happen — and an anti-UV shell resists yellowing over the years.
- IP67 rated — sealed against dust and temporary immersion
- ~2-year battery — a single CR2032 coin cell lasts over two years, and swaps out in seconds
- Anti-UV shell — stays white instead of yellowing with age
Turn a leak alert into action
The T1 doesn't just warn you — it can act. Pair it with an Aqara valve controller and the water shuts off automatically the instant a leak is found. Build your own scenes across the Aqara range, and control everything through Apple Home, Alexa, Google Home, IFTTT or Matter once it's on a hub.
- Auto water shut-off — trigger a compatible valve controller to close the supply
- Works with your ecosystem — Apple Home, Alexa, Google Home, IFTTT and Matter, via an Aqara hub
- Place it anywhere — bathroom, kitchen, balcony, basement or under any appliance
