Quick answers

Is the IKEA of Sweden KAJPLATS E27 WS globe 1521lm Matter certified?
Yes. MatterCatalog matches it to CSA Matter certificate CSA25G27MAT49057-24, certified Dec 16, 2025.
Does the IKEA of Sweden KAJPLATS E27 WS globe 1521lm work with Apple Home or HomeKit?
Likely. It is Matter certified (certificate CSA25G27MAT49057-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Apple Home on a page we hold. Apple says an iPhone using iOS 18 or later can add Matter accessories to the Home app without a home hub. A Thread accessory needs a Thread-enabled home hub such as an Apple TV 4K, HomePod (2nd generation) or HomePod mini, or a compatible third-party Thread border router. Apple’s Matter page lists lights among the accessory types the Home app supports.

Likely. It is Matter certified (certificate CSA25G27MAT49057-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Google Home on a page we hold. Google says you need a Matter-enabled hub device set up on your home wireless network before you can add Matter devices to Google Home. A Thread device needs a hub that is also a Thread border router: Google Home Speaker (2026), Nest Hub (2nd gen), Nest Hub Max, Nest Wifi Pro (Wi-Fi 6E) or Google TV Streamer (4K). Google’s supported-device-types page lists the Color Temperature Light type.

Alexa needs a Matter-compatible Echo; Amazon says its Echo devices support “a subset of Matter 1.5 and lower device types”, so check that yours does. A Thread device needs an Echo with a built-in Thread border router, such as the Echo (4th Gen) or Echo Hub.

What you need to use it with Matter

Thread border router
Needed: it uses Matter over Thread (CSA certificate CSA25G27MAT49057-24). Apple names the Apple TV 4K, HomePod (2nd generation) and HomePod mini; Google names the Google Home Speaker (2026), Nest Hub (2nd gen), Nest Hub Max, Nest Wifi Pro (Wi-Fi 6E) and Google TV Streamer (4K).
IKEA DIRIGERA hub
Optional when your platform already has one of those. IKEA says DIRIGERA includes Thread border router functionality, so it can be the one you use.
Philips Hue Bridge
Not a Thread border router: Philips Hue lists its protocols as Bluetooth and Zigbee. To use this with Hue lights, add both to the same Matter platform.
Apple Home
Apple’s Home app lists lights among the Matter accessory types it supports.
