Door and Window Opening Sensors
Just a couple of centimeters of movement for a sash or door leaf is enough for the system to know instantly — that's how door and window opening sensors from LUMUX smart home devices work. The compact two-part sensor is attached to the frame and the moving element, and any deviation from the norm is detected by the system without delay.
Control without constant presence
Door and window opening sensors are especially useful when the house is empty: in a long-term or short-term absence scenario, any opening outside the schedule triggers a notification to your phone. When residents are home, the same information is used more gently — for example, reminding you to close a window before rain or turning on the air conditioner.
- notification of opening when the owners are away
- monitoring all windows and doors from a single screen
- reminder to close the window when climate control is turned on
- operates in tandem with motion sensors inside the house
Each door and window opening sensor is tied to a specific opening, so the notification doesn't just say "alarm triggered," but the exact location — the office window or the front door. LUMUX adds these sensors to the security scenario along with smart locks, forming a complete perimeter picture. This precision is especially valuable in a multi-story home, where otherwise you would have to manually check all windows and doors.

What do people ask before ordering
No, the opening sensor is installed surface-mounted on the frame and the moving element, without chasing or dismantling — LUMUX installs such devices in a finished renovation, without turning the apartment into a construction site. The two parts of the sensor can be attached to both plastic and wooden windows or doors.
The sensor responds to the position of the specific sash or leaf it is attached to, so it's important to clarify with the engineer during the project stage all window opening modes — tilt, turn, or ajar. This allows setting up the exact notification logic needed for your layout.
Yes, but the reaction is softer than in the absence scenario: for example, the house might remind you to close a window before rain or when the air conditioning is on, rather than raising an alarm. The strict mode with notifications for any opening is activated automatically when the long or short absence scenario is active.
Door and window opening sensors operate on an autonomous power source, not the mains, and the app shows the battery level in advance and sends a low battery notification. The specific maintenance interval depends on the model and intensity of use — the engineer will explain this during the consultation.
