Version 1.2 of the specification was published on 23 October 2023.While a new version it did not include any new categories, only bug fixes and enhancements to existing SDK, API and devices. Version 1.1 of the specification was published on.It introduced support for lighting products (such as mains power plugs, electric lights and switches), door locks, thermostats and heating, ventilation, and air conditioning controllers, blinds and shades, home security sensors (such as door, window and motion sensors), and televisions and streaming video players. Version 1.0 of the specification was published on 4 October 2022.Updates to the standard are planned to occur biannually.

The project group is also expected to be joined by some other board member companies of Zigbee Alliance. 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. Matter products run locally and do not rely on an internet connection, although the standard is designed to talk to the cloud easily.

The standard is based on Internet Protocol (IP) and works through one or several compatible border routers, avoiding the use of multiple proprietary hubs. The goal of the project is to simplify development for smart home product brands and manufacturers while increasing the compatibility of the products for consumers. 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. 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. The Matter software development kit is open-source under the Apache License. Version 1.0 of the specification was published on 4 October 2022. Subsequent members include IKEA, Huawei, and Schneider. It originated in December 2019 as the 'Project Connected Home over IP' (or 'CHIP' for short) working group, founded by Amazon, Apple, Google and the Zigbee Alliance, now called the Connectivity Standards Alliance. The standard is royalty-free, though developers and manufacturers incur certification costs. Matter is an open-source connectivity standard for smart home and IoT (Internet of Things) devices, which aims to improve interoperability/compatibility between different manufacturer and security by always allowing local control as an option.
