# Aqara Door and Window Sensor P2

*Aqara / DW-S02E, DW-S02D*

> The Aqara Door and Window Sensor P2 needs no Aqara hub. It uses native Matter over Thread, so it needs a Thread border router and a Matter controller instead. It runs on a CR123A battery. The tamper alert and adjustable 1-3 cm sensitivity need an Aqara Hub M3. It suits HomeKit, Google Home, Alexa, SmartThings and Home Assistant users, with native support through Matter over Thread.
