IKEA MYGGBETT Door/Window Sensor

Quick verdict

MYGGBETT is IKEA's cheap Matter over Thread contact sensor, and Matter Survey shows it widely used in Home Assistant installs. Budget for a AAA rechargeable and a Thread border router. I haven't run this one; the notes come from IKEA's US product page, the CSA listing and Matter Survey data.

Standout: A low-cost Matter over Thread door and window sensor that needs only a Thread border router.

Compatibility snapshot

Why it stands out

• no IKEA hub needed; any Thread border router works, with DIRIGERA as IKEA's own example
• reports battery level over Matter, and the battery is a replaceable AAA

Reasons to hesitate

• the battery isn't included; IKEA recommends one LADDA rechargeable AAA
• needs a Thread border router before it can be controlled from a phone
• several reviews on IKEA's US page report units disconnecting or failing

Best for

• door and window open/close triggers in a Thread-based Home Assistant setup
• closet or cabinet lights that switch on when a door opens

Avoid if

• you have no Thread border router
• you need a sensor with built-in temperature or vibration sensing

Privacy and local-control notes
