- Does the Kasa KS205 Matter Smart Light Switch 3-Pack work with Apple Home or HomeKit?
- Likely. It is Matter certified (certificate CSA25197MAT45289-24), 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. Apple’s Matter page lists lights among the accessory types the Home app supports.

- Likely. It is Matter certified (certificate CSA25197MAT45289-24), 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. Google’s supported-device-types page lists the On/Off Light type.
- Does the Kasa KS205 Matter Smart Light Switch 3-Pack work with Alexa?
- Likely. It is Matter certified (certificate CSA25197MAT45289-24), so any Matter controller whose app supports its device type can add it. The maker hasn’t named Alexa on a page we hold.
