Matter is a common language for the smart home: bulbs, locks, sensors, curtains and cameras from different brands understand each other and work in one system. Devices talk to each other directly over the home network, without the manufacturer’s cloud, so the home obeys even without the internet. A purchase no longer ties you to one brand: one brand’s switch controls another brand’s lamp, and you can expand the system for years.
How it works
Matter is not a new wire or a new radio but shared rules of conversation on top of familiar networks. Cameras and power-hungry devices work over Wi-Fi or cable. Battery-powered sensors and locks use Thread: a low-power mesh network where every mains-powered device passes the signal on, and the more devices, the stronger the network. A border router links Thread with the home Wi-Fi — it is often built into a smart speaker or hub.
You add a new device with the QR code on the box: the phone finds it over Bluetooth, passes on the network details and checks its certificate — a digital passport that only certified devices receive. From then on all traffic is encrypted. The same device can be added to several apps and hubs at once, and each one will control it — without separate setup with each manufacturer.
Automations — “the door opens, the hallway light comes on” — are stored on a hub inside the home and fire instantly, even if the internet is down. The cloud is needed only for remote access. Version 1.5 added cameras and doorbells to the standard, and certified cameras have been on sale since mid-2026 — so video surveillance joins the same system as the lights and locks.
Where it already works
- Apartments and houses where devices from different brands are brought into one system.
- Turnkey villas and country houses: lighting, climate, curtains, locks and sensors.
- Premium housing: smart home engineering is built into the design.
- Homes with patchy internet: automations run locally, without the cloud.
What to consider
- Check for the Matter logo and the version: cameras and doorbells arrived only in version 1.5.
- Thread sensors need a border router — in a speaker, hub or Wi-Fi router.
- Not every brand feature is available through Matter: some settings stay in the brand’s own app.
- Older Zigbee devices connect only through a bridge — check whether your hub has one.
