Door and window sensors
A door and window sensor (magnetic contact) reports whether a window or door is open. It switches off heating while you air the room, warns you about an open window when leaving and triggers the alarm at night.

How to choose a contact sensor
The sensor has two parts – the sensor with a magnetic contact and a magnet. Look at the size (small sensors fit even into a window frame), the protocol and extras such as temperature or tilt detection.
- Small and discreet – Aqara T1 and P2, Sonoff SenseGuard for normal windows.
- Z-Wave sensors – FIBARO Door/Window Sensor 2 and Aeotec 8 with temperature.
- Wi-Fi and Bluetooth – Shelly BLU and Nous without a hub.
- Tilt sensors – for garage doors and roof windows.
Connect window sensors with smart radiator valves and heating switches off automatically while airing. For complete security see security and access.
Frequently asked questions
Do the sensors work on PVC windows?
Yes, the sensor and magnet stick to the frame and sash. On aluminium frames check the magnet distance.
Will the sensor switch off heating while airing?
Yes, through an automation in the hub that closes the radiator valve when the window opens.
