!!! Overview
[{$pagename}], formerly [Project Connected Home over IP] ([CHIP]), is a [Proposed Standard], [Royalty-free] [Home Automation] connectivity [standard].

%%information
[{$pagename}] is a stupid name for anything. [Matter|Wikipedia:Matter|target='_blank'] is a well known noun.

%%warning
[{$pagename}] is __NOT__ "Free". To use the [{$pagename}] icon or name you must belong to the [Connectivity Standards Alliance] which is prohibitively expensive for an individual.

Announced on December 18th, [2019|Year 2019], [{$pagename}] 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],[2][3] [Comcast] and the [Zigbee Alliance], now [Connectivity Standards Alliance] ([CSA]). Subsequent members include IKEA, Huawei, Schneider, among others.[4][5] Matter-compatible products and software updates for existing products are expected to be released in 2022.[6] Although the Matter code repository is open-source under the Apache license, the Matter specification is licensed by CSA.[7]

[{$pagename}] is an [Application Layer] protocol and [Data model] and does not specify the underlying [Transport Layers].


[{$pagename}] by itself is not a [Smart Home] system. The technology connects devices in the home, but has nothing to do with their automation and control. Such tasks still require a higher-level system that is compatible with matter.



Communication between the devices is based on the Internet Protocol (IP) – both in the home network and in cloud connections. Consequently, the transmission protocols provided for in the first version of the standard are also IP-based. Devices that are to comply with matter use at least one of the following three options:

* [Ethernet] / LAN ([IEEE 802.3])
* [Wi-Fi] / WLAN ([IEEE 802.11])
* [Thread] ([IEEE 802.15.4])
