Highlights

• Low-profile Zigbee magnetic contact sensor designed for doors, windows, or cabinets.
• Powered by a CR1632 coin cell (≈2-year lifespan) and rated for temperatures down to -10 °C.
• Integrates with Mi Home for automations such as entry alerts, bedtime routines, or HVAC cut-off when a window opens.

Pairs with Aqara/Mijia hubs or any Zigbee 1.2 coordinator to deliver instant open/close events to Home Assistant.

Expose contact events locally via ZHA or Zigbee2MQTT; legacy Xiaomi Aqara gateway support also works once LAN mode is enabled.
