Pairing Guide

The Atios KNX Bridge supports two protocols, HomeKit and Matter.

• Apple HomeKit: Established protocol, compatible with Apple Home and Home Assistant.
• Matter: Modern open standard compatible with Apple Home, Google Home, Amazon Alexa, Samsung SmartThings, and Home Assistant.

You can pair the KNX Bridge to either HomeKit or Matter. Matter is the recommended standard. HomeKit continues to be supported for device categories not yet covered by Matter (e.g. garage doors, alarm systems).

Pairing to Matter

Matter pairing requires a Matter controller (e.g. a smart home hub from Apple, Google, Amazon, or Samsung).

1. Navigate to System Settings and enable Matter.
2. Allow the device to reboot. Your existing configuration will remain unchanged.
3. Pair the KNX Bridge in your Matter-compatible app (see below).

Adding Additional Apps via a Paired App

You can add additional Matter ecosystems through an already-paired app without re-pairing the device.
