Matter is an open smart home connectivity standard, developed by the Connectivity Standards Alliance with major platform makers, that lets devices from different brands work with multiple ecosystems. It runs over IP networks using Wi-Fi, Ethernet, or Thread, and uses Bluetooth LE for setup.
Why it matters
Before Matter, a smart bulb often worked only with the hubs and apps its maker supported. Matter aims to give devices a common language so one device can be controlled by several platforms at once, through a feature called multi-admin. Control happens locally on the network where possible, which reduces dependence on the cloud.
Matter is not a radio technology. It is an application layer on top of existing networks. Battery-powered low-energy devices often use Thread, a mesh network that needs a Thread border router, often built into a smart speaker or hub.
Example
Setup usually involves scanning a QR code on the device with a phone. The same bulb can then be shared with a second ecosystem by generating a pairing code in the first app and entering it in the second.
Common mistakes
- Expecting every feature of a device to be exposed through Matter; some advanced functions still need the vendor app.
- Forgetting a border router is needed for Thread devices.
- Assuming old Zigbee or Z-Wave devices work directly; they typically need a bridge.
