 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.
 
-## Bridge devices
-
-One of the great things about Matter is that you can have both Wi-Fi and Thread based devices on the same controller.
-Next to actual devices (like actors or sensors), you will also see bridges. The bridge connects the network over Ethernet or Wi-Fi and bridges multiple devices into a Matter network. A great example is the Philips Hue V2 bridge, which is a Zigbee hub and a Matter bridge. This bridge exposes all Zigbee devices already connected to the bridge as Matter devices on the network. Also, Aqara, SwitchBot, and IKEA have launched such Hub devices.

 Matter goes hand-in-hand with (but is not the same as) {% term Thread %}. {% term Thread %} is a low power radio mesh networking technology. Much like Zigbee, but with the key difference that it is _IP-addressable_, making it the perfect companion transport protocol for Matter.

 For some ecosystems, you can add some of their non-Matter devices into Home Assistant via a *Matter bridge*. Examples of Matter bridges are the SwitchBot&nbsp;Hub&nbsp;2, Aqara&nbsp;Hub&nbsp;M2, Ikea&nbsp;Dirigera, or the Philips Hue Bridge. Using a bridge allows you to keep controlling these devices via their native App, while having them available in Home Assistant at the same time. The Aquara Hub, for example, uses a cloud-based integration. By bridging it into Home Assistant via Matter (instead of using their cloud-based integration), you can make it use local communication.

 #### How to add a Matter bridge to Home Assistant
 
 How you add a bridge to Home Assistant depends on the device. Check the documentation of that device for the specific steps. In case of SwitchBot&nbsp;Hub&nbsp;2, for example, you need to enable the Matter-paring mode within the app. It then gives you a pairing code and tells you to set the actual device into pairing mode. You can then add that bridge device to Home Assistant as a Matter device. There is no guarantee that all the devices from that ecosystem can be used in Home Assistant. SwitchBot Hub 2 V1.5, for example, allows you to use curtain, lock, and blind via Matter, but not light.
