Integrate the IKEA MYGGSPRAY Motion Sensor with Matter into Home Assistant

With the MYGGSPRAY motion sensor, IKEA offers a compact Matter-enabled motion sensor that works not only within the IKEA ecosystem but also with open platforms such as Home Assistant. This article explains how the sensor works, what you need and how to integrate it into Home Assistant.

IKEA MYGGSPRAY at a glance

The IKEA MYGGSPRAY wireless motion sensor is a small, round sensor made of white plastic. It detects motion and also measures ambient light, allowing lights and other devices to be controlled according to movement or dusk. Its understated design makes it easy to install discreetly in rooms, stairwells, garages, bicycle parking areas or outbuildings.

The removable back is shaped to support corner mounting. You can attach the sensor using screws or the supplied adhesive pads. It is powered by two AAA batteries, with IKEA specifying a battery life of up to 15 months. The sensor is suitable for indoor and outdoor use, although outdoor installations should be protected from direct exposure to the weather.

IKEA MYGGSPRAY and Matter

MYGGSPRAY is based on the open Matter standard, making it compatible with products from different manufacturers. It can connect to platforms such as Amazon Alexa, Apple HomeKit, Google Home, Homey and Samsung SmartThings. Matter therefore makes the sensor highly flexible.

Requirements for integration with Home Assistant

For a smooth integration, you will need the following:

• A current version of Home Assistant running on suitable hardware, such as:
  • Raspberry Pi*
  • Home Assistant Green*
  • Home Assistant Yellow*

• A working Thread Border Router, such as:
  • Aqara Smart Hub M200*
  • Home Assistant Connect ZBT-2*
  • Amazon Echo Show 11*

• IKEA MYGGSPRAY with AAA rechargeable batteries* installed
• The Matter QR code or numeric pairing code printed on the front of the instructions and on top of the sensor.

Setting up MYGGSPRAY in Home Assistant

Matter devices are currently added through the Home Assistant Companion app on a smartphone.

After you insert the batteries, the sensor starts automatically and remains in pairing mode for 15 minutes. Briefly removing a battery restarts this period. If the sensor is already connected to another system, use the button inside the battery compartment to reset it.

Step by step

1. In the app, open: Settings → Add to Home Assistant → Add device → Add Matter device
2. Select New, then scan the QR code or enter the pairing code manually
3. If you have several border routers, select the desired Thread network

After a few seconds, MYGGSPRAY appears as a new device in Home Assistant.

MYGGSPRAY in Home Assistant: features and data

The device information shows the firmware version, hardware version and connection type (Matter). The sensor overview indicates whether motion is currently detected and displays the measured light level.

The status switches between Clear and Occupied. You can adjust the label in Home Assistant, for example by renaming the Occupancy attribute to Motion.
Under Configuration, Home Assistant shows whether the firmware is up to date. The Diagnostics section provides the battery level, battery voltage and battery type (AAA). An Identify function is also available and lights the status LED.

The sensor can be assigned directly to automations, scenes or scripts. Any actions that use the sensor are also listed here, while Activity shows its most recent events.

Some values can be opened in detail and displayed as a chart or as an activity history over time.

Practical example: automations with MYGGSPRAY

In the test, MYGGSPRAY was paired with an IKEA KAJPLATS E27 LED bulb. The light switches on when motion is detected and turns off automatically when no further movement is detected. Setting this up in Home Assistant took only a few minutes and used two automations. The duration for which the Motion detected state remains active cannot be adjusted. In the test, the light switched off after about 30 seconds without further movement.

Conclusion

The IKEA MYGGSPRAY motion sensor is a compact and versatile Matter sensor that stands out for its easy integration with Home Assistant. It suits many indoor and sheltered outdoor uses and provides a solid basis for automated lighting and device control.
Another advantage is its attractive price, which is lower than comparable solutions from manufacturers such as Homematic or Aqara.
