Full details →Who the Aqara Door and Window Sensor P2 is for

Avoid it if: Anyone without a Thread border router. Thread is a mesh with no route to your phone otherwise.
Who the Aqara Water Leak Sensor T1 is for
Buy it if: Anyone with a geyser, water tank, or washing machine on a floor that would be expensive to water-damage.
Avoid it if: Anyone without a Zigbee hub -- there is no standalone siren on the sensor itself.
