Who it’s for
- Security & Access Integrators
- US or Canadian project owners working with an appropriately qualified local installer
The project challenge
- A rear or side entrance can stay open after routine household use.
What the system should achieve
- Notify a named resident when an agreed secondary opening is left open.
Recommended system architecture
- Opening-state sensor → Thread border router → supported Matter controller → permitted state rule
- Use alerts to prompt inspection; do not infer identity or an intrusion from an opening alone.
Equipment & ecosystem choices
- Aqara Door and Window Sensor P2
- A supported Matter controller and Thread border router; other sensor brands require their own model check
Installation & technical requirements
- Check mounting surfaces and magnet alignment through the full door/window travel; test open, closed and offline states.
- Site acceptance focus: Notify a named resident when an agreed secondary opening is left open.
Compatibility & construction constraints
- P2 uses Matter over Thread, not Zigbee pairing. Verify the target platform exposes the required contact state and notification action.
- Set an owner-approved delay so ordinary ventilation does not cause repeated alerts.
Make it your own
- For secondary-door status alerts, confirm room/door/zone counts, agreed controls, notification recipients and installation stage.
- Specific decision: Set an owner-approved delay so ordinary ventilation does not cause repeated alerts.
Preliminary equipment plan
- One contact pair per independently monitored opening; border routers and powered Thread infrastructure by coverage survey.
- Scale by the surveyed scope for secondary-door status alerts, not by a fixed package advertised without a site schedule.
What shapes the budget
- Opening count, mounting material, radio coverage and the supported controller already owned by the customer.
- Country/city, labor, taxes, shipping, warranty route and confirmed supply source; no price or stock is assumed.
