Quick answers

Is the Ltech KMS1 Controller Matter certified?

Does the Ltech KMS1 Controller work with Apple Home or HomeKit?

Likely. It is Matter certified (certificate CSA261AVMAT51095-24), 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.

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 On/Off Light type.
