Mini Door/Window Sensor

Getting alerted every time a door or window opens or closes

Written by Cath Smith
Updated today

The Mini Door/Window Sensor detects when any door or window opens or closes and instantly sends an alert to your Abode Hub, triggering a chime, a push notification, or an alarm depending on your system settings. With up to 4 years of battery life and tool-free adhesive installation, it's the simplest way to protect every entry point in your home.

TIP

You can also use this sensor to trigger CUE automations — for example, turn on a light every time the front door opens.

Parts overview

Part

What it does

1. Magnet Alignment Area

Textured surface on sensor body. Align the magnet to this area when mounting

2. Red LED Indicator

Shows battery low status and flickers during Test Mode when triggered

3. Tamper Switch

Sends a tamper alert to the Hub when activated

4. Battery Compartment

Houses the CR2450 coin cell battery

5. Pairing / Test Button

Press once to pair; press once to enter 3-minute Test Mode

6. Bottom Fixing Screw

Prevents accidental removal of battery

7. Tamper Compression Mark

Ensures Tamper Switch is engaged

8. Magnet

Engages the Door Sensor

9. Magnet Spacer

Mounting

LED status guide

In normal operation, the LED stays off. It will only light up in these situations:

• Battery is low

• Sensor is in Test Mode and detects the magnet moving

Pairing your Mini Door/Window Sensor

1. Make sure you have the latest version of the Abode app installed.

2. In the app, tap the Menu (≡) icon, then tap "+ Add Device".

3. Tap "Door & Window Sensors", then "Mini Door Sensor".

4. Unbox the sensor and magnet, then tap "Continue".

5. Press the Pairing/Test Button on the back of the sensor body once. The red LED will flicker and the device will be added. A green checkmark will confirm success.

6. Name your new sensor and tap Next to finish.

TIP

After pairing, test the sensor by placing the magnet over the Magnet Alignment Area, then pulling it away. You should hear a Hub chime and see a door open event in the app Timeline. This is a great way to confirm wireless range before you commit to a mounting location.

Testing before you mount

Use Test Mode to confirm wireless range and placement before sticking anything to your doors or windows.

1. Press the Pairing/Test Button once to enter Test Mode (active for 3 minutes).

2. Move the magnet toward and away from the sensor. The LED will light up each time a signal is detected.

3. Walk around your intended mounting location to verify the Hub receives each signal.

Installing your Mini Door/Window Sensor

Installation tips

• Allows up to a 0.75-inch gap between sensor body and magnet — use the offset spacer if needed

• Avoid mounting near metal objects like door locks or metallic door frames — they can interfere with the magnet

• Align the sensor magnet with the textured Magnet Alignment Area on the sensor body for best results

Adhesive mounting (recommended)

1. Clean and dry both mounting surfaces.

2. Remove the adhesive backing from the Velcro strip and press it firmly to the back of the sensor body.

3. Remove the adhesive backing from the magnet.

4. Remove the remaining Velcro backing from the sensor body.

5. Press the sensor body onto the door frame, and the magnet onto the door itself. Align the magnet to the Magnet Alignment Area.

6. If the frame prevents close alignment, attach the offset spacer to the magnet first, then mount the magnet on the spacer.

Replacing the battery

The sensor uses one CR2450 Lithium battery with up to 4 years of life. You'll receive a notification in the app when it's low.

For sensors purchased November 2024 or later

1. Undo the bottom fixing screw to separate the cover and base.

2. Use a flat tool to pry the base from the cover on one side, then the other.

3. Remove the old battery with a flat tool. Press the Test Button 5–6 times to drain residual power.

4. Insert a new battery with the positive (+) side facing up.

5. Re-hook the base into the cover, close, and tighten the fixing screw.

For sensors purchased before November 2024

1. Use a coin or flat screwdriver to pop open the case.

2. Remove the CR2450 battery. The negative (-) side should face down when replacing.

3. Replace the cover, aligning the Tamper Compression Mark with the Tamper Switch, then snap closed.
