What You Will Need

Eve Door & Window Sensor (Matter)
CR2032 coin cell battery (pre-installed)
iPhone or iPad with the Eve app installed
Matter-compatible home hub (Apple TV, HomePod, or other Matter controller)
Adhesive strips (included) or small screws for mounting

Step 1: Plan Your Sensor Placement

The Eve Door & Window Sensor (Matter) is a two-piece magnetic contact sensor that detects when a door or window is opened or closed. Before installing, decide which door or window to monitor. The most impactful locations are:

Entry doors — to trigger welcome automations or security alerts
Garage doors — to know if the garage was left open
Windows — to automate HVAC behavior when windows are opened
Cabinet or closet doors — for access monitoring

Step 2: Add the Sensor to Your Smart Home

Ensure the CR2032 battery is active. Remove any protective tab if present.
Open the Eve app on your iPhone or iPad.
Tap Add Accessory.
Scan the Matter setup code on the sensor or included card.
The app will connect via Thread (preferred) or Bluetooth.
Assign the sensor to a room and give it a name, such as "Front Door" or "Kitchen Window."

As a Matter-enabled sensor, the Eve Door & Window works with Apple HomeKit, Google Home, Amazon Alexa, and Samsung SmartThings. Select your preferred platform during the pairing process.

Step 3: Mount the Sensor Body

Clean the mounting surface on the door or window frame with a dry cloth.
Peel the adhesive backing from the mounting strip.
Press the sensor body (the larger piece) firmly onto the frame and hold for 30 seconds.
Position it near the edge of the frame where the door or window meets the frame when closed.

Step 4: Mount the Magnet

Clean the surface on the door or window itself (the moving part).
Peel the adhesive backing from the magnet's mounting strip.
Align the magnet (the smaller piece) directly adjacent to the sensor body when the door or window is in the closed position.
The gap between the sensor and magnet should be no more than 15 mm (about half an inch) when closed.
Press firmly and hold for 30 seconds.

For permanent installations on exterior doors, consider using small screws instead of adhesive for a more durable mount that withstands temperature changes and vibration.

Step 5: Test the Sensor

Open the door or window slowly.
Check the Eve app or your smart home app to confirm the status shows "Open."
Close the door or window.
Verify the status updates to "Closed."

The transition should register within one to two seconds. If the status does not change, reposition the magnet closer to the sensor body.

Step 6: Set Up Automations

The real power of the Eve Door & Window Sensor is in automations. Create rules that respond to open and close events:

Turn on a light when the front door opens, and turn it off two minutes after the door closes.
Pause your HVAC system when a window is opened to save energy.
Send an alert if a door is opened while everyone is away from home.
Trigger a "Good Night" check to notify you if any doors or windows are still open at bedtime.

Create automations in the Eve app, Apple Home app, or your preferred smart home platform.

Step 7: Review Event History

The Eve app maintains a detailed log of every open and close event, including timestamps and duration. This history helps you identify patterns, such as how often a door is used, how long windows stay open, or whether someone accessed a cabinet at an unusual hour.

Tips for Best Performance

The Matter version supports Thread networking, providing faster and more reliable communication than Bluetooth. Ensure a Thread border router (HomePod Mini, Apple TV 4K) is within range.
The CR2032 battery lasts approximately one year. Replace it when the app shows a low battery notification.
For sliding doors, mount the sensor on the track frame and the magnet on the door panel edge.
Avoid mounting on metal surfaces or near strong magnets, which can interfere with the contact detection.
Multiple sensors can be grouped in the Home app to check the status of all doors and windows at a glance.
