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. 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. The project group was launched and introduced by Amazon, Apple, Google, Comcast and the Zigbee Alliance, now Connectivity Standards Alliance (CSA). Subsequent members include IKEA, Huawei, and Schneider. Matter-compatible software updates for many existing hubs became available in late 2022, with Matter-enabled devices and software updates expected to be released during 2023.Version 1.0 of the specification was published on 4 October 2022. The Matter specification is provided at no charge upon request after providing full name, company name, email address and consent to their privacy policy, but cannot be redistributed without permission from CSA.
