What is Matter, and why is it different?

What is Matter?

https://github.com/project-chip/connectedhomeip

Matter is a unified connectivity technology for the smart home. It is not a smart home platform like Apple HomeKit, Google Home, and Amazon’s Alexa. Matter doesn’t automate or control your home; it simply provides the pipes and language for devices to communicate.

Matter will start as an application layer on top of existing IP technologies, including ethernet, Wi-Fi, Thread, and Bluetooth (for device provisioning). This means Matter is not reinventing the wheel; it’s adding better technology to the highways our smart homes are driving on.

Matter 是基于互联网协议 (Internet Protocol, IP) 定义的通用应用层。因此，无论底层采用何种 IP 网络协议，Matter 应用层都能够保证设备间的互操作性。在即将发布的第一版 Matter 协议中，它将首先支持以太网、Wi-Fi 和 Thread 网络协议。

Matter is an app-layer standard that works on top of IP-based protocols such as Thread. It's not a networking protocol itself.

而如今比较流行的两种通信协议一种是WiFi，另一种是Thread。基于Matter实用WiFi技术及叫Matter over WiFi，基于Matter使用Thread技术叫Matter over Thread。

如果把Matter看作是铁路交通方式，WiFi就像是高铁，Thread像是地铁。WiFi具有高带宽，高功耗的特性，就像高铁可以把你送到很远的地方，但是耗时长票价也会更贵。Thread就具有低带宽，低功耗的特性，就像地铁虽然只能在本地运输，但是耗时短票价低。

之所以这两种协议成为主流是因为，二者都支持IP。像在铁路运输网络中，无论是高铁车厢还是地铁车厢都支持在铁轨上运行一样。

A Matter network map shows how devices will connect to each other, to the internet, and to other protocols using Wi-Fi, Thread, and Matter controllers.

Once in your home, Matter devices can operate entirely locally, talking to each other over Thread and Wi-Fi and not going through the cloud. 

That means if your internet goes down, your smart home will still work.

 Devices will still need to communicate with the internet for out-of-home control and firmware and security upgrades, which will happen directly or through a Matter controller device (i.e., a smart speaker, smartphone, or bridge). Local control is a significant step in maintaining privacy in the smart home, a big concern for people when considering installing smart home devices.

Aqara Aqara smart Hub M1s Gen 2

Aqara has just introduced the updated version of its Hub M1s. The Aqara smart Hub M1s Gen 2 brings significant improvements in terms of WiFi security protocol alongside compatibility to the future Matter smart home standard.

20220701

Aqara Announces Matter Support for M2 and M1S Hubs

Aqara has just announced that two of their newer internationally available hubs will be compatible with the forthcoming Matter Certification standard.

The Company plans to provide global consumers with a variety of Matter-compatible products. As the first step, Aqara will integrate Matter into its existing hubs – Aqara M1S and M2 – through a software update (OTA). The updated Aqara M2 and M1S hubs will enable certain new and existing Aqara child devices to be compatible with Matter.

he first Matter-compatible Aqara child devices will include the latest sensors, wall switches, and smart plugs. Integration with Matter will not disrupt current Aqara smart homes so users will continue to enjoy the same features and benefits of Aqara’s existing Zigbee devices.

Thread 边界路由器

Thread 是一套基于 IPv6 的低功耗 mesh 网络协议，常用于物联网产品。Thread 协议是基于 IEEE 802.15.4 技术，因此 Thread 网络中的设备无法直接与 Wi-Fi 或以太网设备通信。为了使 Thread 设备与其他网络中的设备互联，我们需要在 Matter 的拓扑结构中增加一个特殊设备：Thread 边界路由器。

https://zhuanlan.zhihu.com/p/463015234

Thread 边界路由器负责在 Wi-Fi 和 Thread 网络之间转发 IP 帧

例如，一个 Thread Matter 开关可以控制一个 Wi-Fi Matter 灯泡；同理，一个 Wi-Fi Matter 开关也可以控制一个 Thread Matter 灯泡，而且这些过程均无需借助手机 App、云或其他特别操作。

乐鑫 Thread 边界路由器解决方案

乐鑫自 Matter 发起之初就积极加入并开发 Matter 项目，现已能够为用户提供全功能的 Matter 协议解决方案，包括使用 Wi-Fi/Thread 连接的 Matter 终端设备，以及使用乐鑫 SoC 组合搭建的 Thread 边界路由器/Zigbee 桥接设备。

Thread 边界路由器示例和 SDK 现已对用户开放。本示例中，用户需要通过 UART 或 SPI 将一颗 Wi-Fi 芯片和一颗 802.15.4 芯片相连。

How Does Matter Work?

Matter will use Thread or Wi-Fi for communication between smart home devices and hubs. When Matter-ready devices start rolling out, most of the devices will rely on Thread because it offers low power and low latency with a wireless mesh networking system. However, some devices will rely on Wi-Fi as well. Also, Matter will use Bluetooth for device provisioning which will make the entire set up process seamless.

Here is what Matter Network Stack looks like:

Let me walk through what a simple setup process of a Matter device with Wi-Fi will look like.

Turn on the Matter device
Connect the mobile phone to the home Wi-Fi network and turn on Bluetooth
Scan the QR code on the Matter device
The phone will send the device credentials over to the Matter server on the same network
The matter device will connect with the Matter server
