Matter functions & installation
This bridge exposes supported KNX functions to a Matter platform. Its configuration, firmware and supported endpoint types determine which controls and readings are available.
Documented Matter functions
- Light on/off and dimming
- Switched sockets
- Shutter and blind movement
- Supported thermostats, including virtual thermostats
- Temperature and humidity sensors
- Binary inputs
Commission the KNX installation in ETS, then configure the bridge with the required group addresses, data types and status feedback. Check the exact bridge firmware and your Matter platform. Native KNX functions, electrical ratings and Matter functions are separate specifications.
Bridge setup: commands, readings and feedback
Match the ETS group objects to the selected bridge and receiving app. These examples explain configuration requirements; they do not establish compatibility with every bridge.
Switching and dimming
Configure commands and readable status feedback. 1Home requires absolute brightness values for percentage control; relative wall-button dimming alone is insufficient.
1Home instructions ↗Shades and blinds
Map movement, stop and position feedback. Slat adjustment needs matching objects. A timed-position fallback estimates position instead of measuring it.
1Home instructions ↗Climate and sensors
Keep measured temperature and humidity separate from setpoints. A valve output alone is not a complete thermostat. Atios documents the required group addresses for each accessory.
Atios instructions ↗Extra KNX values
1Home can display generic KNX data in its own app without exporting it to Matter. Do not assume that energy, wind, rain or diagnostic values appear in every Matter app.

Model, firmware & function limitations (6)
- Exports up to 128 KNX devices, despite supporting up to 500 devices inside domovea.
- Matter-to-domovea device import is not provided by the bridge.
- Internal groups, sequences and camera integrations are not automatically exposed to Matter.
- App support can limit exported functionality.
- TJAS471 is the current Matter-equipped model; do not assume equivalent support in older TJA470 hardware.
- Exact manufacturer model page and CSA certificate confirm the Matter bridge over Ethernet.
