Xiaomi Door Window Sensor

This catalog entry represents a Xiaomi/Mijia-compatible magnetic door/window contact sensor. It is intended to report when a door or window opens or closes, enabling security notifications and automations such as lighting or HVAC actions.

The representative source set is mixed: some offers clearly identify Mi Door and Window Sensor 2, while several others are Aqara Zigbee door sensors sold for Xiaomi Home. Those are different hardware families with different protocols, so the public Specifications should not force a Bluetooth or Zigbee model onto the canonical entry without a trustworthy exact-model identifier. The current brand and product type are therefore retained as the safe shared facts.

Mi Home compatibility is well supported across the source set, but the required gateway depends on the actual sensor generation. Mi Door and Window Sensor 2 uses Bluetooth 5.1, while legacy Aqara variants use Zigbee.
