Frequently asked questions
Does the Aqara sensor need a hub?
A compatible Aqara hub is required for full alerts, automations, and ecosystem integrations. Check hub and regional compatibility before buying.
Is it a complete security system?
No. A contact sensor can report open or closed status and trigger routines, but it does not replace monitored security, appropriate locks, or professional safety equipment.
Where is a contact sensor most useful?
Doors and windows are obvious uses, but cabinets, closets, and mailbox-style enclosures can also trigger helpful routines when placement and wireless range allow.
