# What is Matter?
# Introduction- What is Matter?
Matter is [the new standard for home automation](<https://en.wikipedia.org/wiki/Matter_(standard)>), which has been released recently. It is in the process of being adopted by the tech industry. Matter is a local protocol. Device control is done without the need of any cloud. From a technical perspective, you can use a Matter-compatible device with Home Assistant without connecting to a vendor-specific cloud. However, some vendors may require you to set up an account before you can enable Matter.
Matter is a new smart home connectivity standard for home automation products and IoT (Internet of Things) devices, see its [Wikipedia article](https://en.wikipedia.org/wiki/Matter_(standard)).
Unlike the radio based protocols we're already familiar with in the IoT landscape, like Zigbee and Z-Wave, Matter uses standard IP-based communication. Matter is not a radio protocol, but a control protocol that runs on top of the existing network infrastructure, using your existing Wi-Fi/Ethernet routers and Thread.
The initial version 1.0 release of Matter was published in October of 2022. Matter is still in the process of being adopted in the smart home market. It has gotten much publicity because of its promise of interoperability across all ecosystems. The largest tech companies like Google, Apple and Amazon teamed up to develop this new smart home connectivity standard under the roof of the CSA ([Connectivity Standards Alliance](https://csa-iot.org/)). The largest tech companies that are already active in the home automation market have announced that they are or will be working on Matter-compatible products and also joined the development effort.
Home Assistant is a so-called _controller_, it can control Matter based devices. Other examples of Matter controllers are the Google Nest speakers, Apple HomePods, and a SmartThings Station.
Matter products run locally and always allow local control, with device control done without the need for any internet connection or cloud services. From a technical perspective, you can use a Matter-compatible device with Home Assistant without connecting to a vendor-specific cloud. However, some vendors may require you to set up an account before you can enable Matter support for some products, (especially for commercial manufacturer's own branded gateways/bridges/hubs/controllers sold as appliances).
Unlike other common radio-based protocols for IoT, (like Zigbee, Z-Wave, and Bluetooth), the Matter standard specification itself does not contain its own proprietary radio protocol or network transport protocol, but instead, it is a service control protocol that runs **on top** of the existing network infrastructure at the application level, with all Matter devices communicating using standard IP-based (IPv6) communication over your existing [local area network (i.e. LAN networks like Wi-Fi and Ethernet)](https://en.wikipedia.org/wiki/Local_area_network) or [Thread (Low-Power Wireless Personal Area Network)](https://en.wikipedia.org/wiki/Thread_(network_protocol)) depending on the type of device.
Home Assistant is a so-called "_controller_" in a Matter ecosystem, meaning that it can control Matter-based devices. Other examples of Matter controllers are the Google Nest products, Apple HomePod speakers, Samsung SmartThings Station, and some newer Amazon Echo devices.
