Matter goes back to a joint initiative of Amazon, Apple, Comcast, Google, SmartThings and the then called Zigbee Alliance. The founding members launched a project called Connected Home over IP, later also known by the acronym CHIP, at the end of 2019. Other companies joined and the working group now has over 300 members. Thousands of engineers and software developers are working on the standard worldwide. One result of this collaboration is the software code, which is open source and freely accessible to everyone (link). In May 2021, first specifications were set – along with a new name. Since then, the CHIP project has been called Matter. In parallel, the Zigbee Alliance has renamed itself the Connectivity Standards Alliance (CSA, link). As an umbrella organization, it manages not only the Zigbee standard in its various manifestations, but also the Matter project. The CSA is also responsible for product certification. Before devices are allowed to carry an official Matter logo, they must have passed tests at authorized testing institutes.
