Matter, formerly Project Connected Home over IP (CHIP), is a proprietary standard for home automation that is royalty-free, with manufacturers only incurring certification costs.[2] Announced on 18 December 2019, Matter aims to reduce fragmentation across different vendors, and achieve interoperability among smart home devices and Internet of things (IoT) platforms from different providers.[3][4] The project group was launched and introduced by Amazon, Apple, Google,[5][6] Comcast and the Zigbee Alliance, now Connectivity Standards Alliance (CSA). Subsequent members include IKEA, Huawei, and Schneider.[7][8] Matter-compatible software updates for many existing hubs became available in late 2022,[9][10][11] with Matter-enabled devices and software updates expected to be released during 2023.[12]

Version 1.0 of the specification was published on 4 October 2022.[1][13][14] The Matter specification is provided at no charge upon request after providing full name, company name, email address and consenting to their privacy policy, but cannot be redistributed without permission from CSA.[15] The Matter software development kit is open-source under the Apache License.[16]


In December 2019, Amazon, Apple, Google, Samsung SmartThings and the Zigbee Alliance announced the collaboration and formation of the working group of Project Connected Home over IP. The goal of the project is to simplify development for smart home products brands and manufacturers, while increasing the compatibility of the products for consumers.[17][18]

The standard is based on Internet Protocol (IP) and works through one or several compatible border routers, avoiding the use of multiple proprietary hubs. Matter products run locally and do not rely on an internet connection, although the standard is designed to talk to the cloud easily. It is intended to enable cross-platform of smart home devices, mobile apps, and cloud services, and defines a specific set of IP-based networking technologies for device certification.

The project group is also expected to be joined by some other board member companies of Zigbee Alliance.[19]


Updates to the standard are planned to occur every six months, although the next version is expected to be published 18 months after the first version was published and include new features, devices, device types and certification methods.
