Core terms
Matter controller
The platform-side device or software that commissions and controls supported Matter endpoints. It is not automatically a Thread border router.
Thread border router
A node that routes between a Thread mesh and the home IP network. A plain Thread radio may lack this role.
Matter bridge
A device that presents selected non-Matter children as Matter endpoints. Exposed features depend on its firmware and endpoint mapping.
Commissioner
The phone or controller initiating a secure Matter addition. Commissioning access does not equal ongoing platform feature support.
Matter fabric
A secure administrative domain for Matter devices. Multi-Admin can give an accessory membership in more than one fabric.
Endpoint
A logical device function exposed to a controller. A bridge may export only certain endpoints from a physical child.
mDNS
Local network discovery used by some pairing flows. Network isolation or blocked multicast can make a device appear missing.
VLAN
A network segment. Separating phone, controller and accessory can interrupt discovery unless the network is configured for it.
Multi-Admin
Matter sharing across controllers. An already paired accessory generally needs a newly generated sharing code from its current administrator.
US SKU
A saleable US product variant. A marketing family or international product page alone does not prove a particular US electrical or radio configuration.
