Can connect directly to Home Assistant without Aqara Hub
Aqara sensors work great for Home Assistant and don't require the Aqara Hub (even though it says it does). The metal parts that detect the water leak are actually screws, so you can use them to attach some wire instead, if you have to detect a leak in a place where you can't (or don't want to) place this sensor. This is helpful if it is a very small space, or somewhere the sensor could be damaged, or somewhere where the Zigbee signal could be blocked, such as inside a metal enclosure.

Excellent water leak sensors — easy to set up and reliable!
I’m really impressed with this Aqara Water Leak Sensor 3 Pack. Setup was quick and seamless using the Aqara Hub, and the Zigbee connection has been rock-solid ever since. The sensors are compact and easy to place—perfect for under sinks, near appliances, or in the basement. I tested them with a small amount of water, and they instantly triggered an alert through the app. Notifications come in fast, which gives great peace of mind. I also love that it works with IFTTT, so you can integrate it into your broader smart home setup. This is a great investment for anyone looking to prevent water damage and stay ahead of potential leaks. Highly recommend!

Ottimi
Eccellenti. Vanno con una pila tonda. Per configurarli basta tenerli premuti. Rilevano subito la presenza di acqua e chiudono la valvola evitando allagamenti. Fantastico

Easy to setup on Aqara Hub. No Smartthings Matter bridge compatibility.
Easy to setup on Aqara Hub. Fast connection and works are expected. A little disappointed that there is no SmartThings Matter bridge compatibility to connect to the SmartThings ecosystem.
