Formerly called Project CHIP (Connected Home over IP), the open source interoperability standard known as Matter arrived in 2022. Device manufacturers must comply with the Matter standard to ensure their devices are compatible with smart home and voice services such as Amazon’s Alexa, Apple’s Siri, Google’s Assistant, and others. For folks building a smart home, Matter theoretically lets you buy any device and use the voice assistant or platform you prefer to control it. For example, you can buy a Matter-supported smart bulb and set it up with Apple HomeKit, Google Assistant, or Amazon Alexa—without having to worry about compatibility. Bringing the main smart home platforms (Amazon Alexa, Apple HomeKit, Google Home, and Samsung SmartThings) to the same table is an achievement.
