What You'll Need

Step-by-Step Setup

Unpack components: You'll have a main sensor body and a small magnet piece.
Remove battery tab: Pull the plastic tab to activate the pre-installed CR2032 battery.
Open Matter controller: Apple Home, Google Home, or other compatible app.
Add accessory: Tap "+" to add a new device.
Scan Matter code: Find the QR code on the sensor or packaging and scan it.
Wait for connection: The sensor connects via Thread network to your border router.
Assign room: Place the sensor in the appropriate room.
Mount the sensor: Clean the surface, apply adhesive tape, and mount the main sensor on the door/window frame.
Mount the magnet: Attach the magnet on the moving part (door/window) aligned with the sensor mark.
Test operation: Open and close the door/window to verify detection.

Not pairing: Ensure Thread border router is online. Reset sensor by inserting a pin into the reset hole for 5 seconds. Move closer during setup.
Status not updating: Check alignment—magnet and sensor must be within 15mm when closed. Verify sensor is online in app.
False alerts: Reposition magnet for better alignment. Ensure adhesive is secure. Check for vibration sources.
Battery draining: Frequent open/close events use more power. Check for loose magnet causing repeated triggers.
Delayed notifications: Check Thread network health. Ensure border router is within reasonable range.
