Magnetic Contact Pair · Up to 2-Year Battery · Instant Alerts
In Stock
A two-piece magnetic contact that reports the moment a door or window opens — and, just as usefully, that it is still shut. Stick it on in a minute with adhesive, no wiring and no drilling. It drives the useful rules: the porch light when the gate door opens after dark, an alert if a window opens while the house is armed, the AC refusing to run against an open balcony door, and the front door fed into the Elderly Care inactivity watch.

Setup Process
How It Works
1
Stick It On
Fix the sensor to the frame and the magnet to the door or window with adhesive. No wiring or drilling.
2
Join the Hub
Add the Door & Window Sensor to your Nexomatic hub so its state shows on the dashboard.
3
Name and Place It
Label it — Front Door, Balcony, Terrace — and assign it to a room in the app.
4
Set Your Rules
Turn on armed-mode alerts, a left-open reminder, the porch-light rule or an AC hold-off for that door.
Key Features
Built for Indian Homes
Knows Shut, Not Just Opened
The state is on the dashboard, so the question "did I leave the balcony open" has an answer from anywhere — no walking back to check.
Armed-Mode Alerts
A window opening while nobody should be home raises a push alert immediately, and can fire the lights and the siren with it.
Left-Open Reminder
A door held open past a threshold you set — the fridge room, the main gate, the terrace door — reminds someone rather than waiting to be noticed.
Stops the AC Fighting a Window
An open balcony door can hold the AC or the geyser off, so the room stops paying to cool the street.
Elderly Care Input
Front-door activity joins the inactivity watch: no motion and no door movement through the awake window raises a family alert.
Two Years, Then a Warning
Low battery is flagged in advance in your language, so a sensor never goes quietly dead on a door you rely on.

Frequently asked questions
How long does the battery last?
Up to 2 years. You get a low-battery alert in your language before it dies.
Do I need to drill or wire anything?
No. It mounts with adhesive in about a minute.
Does it need the Nexomatic hub?
Yes. It joins the Nexomatic hub, which runs the rules and sends the alerts.
Can I check if a door is closed when I am away?
Yes. The open or closed state is on the dashboard, so you can check from anywhere.
Will it alert me if a window opens while I am out?
Yes. In armed mode a window opening raises a push alert immediately, and can fire the lights and siren with it.
