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
- On/off, dimmable, tunable-white and RGB lights
- Thermostats and air conditioning
- Switched sockets
- Roller shutters and venetian blinds
- Door locks and push buttons
- Contact, temperature, humidity, illuminance and occupancy sensors
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 (4)
- The manufacturer installation manual states that the Elsner unit is identical to the 1Home Server KNX Pro and redirects to 1Home documentation. Confirm installed firmware, enabled features and licensing for the purchased Elsner unit.
- Matter certification is stated in the manufacturer manual; an independently matched certificate ID for this branded SKU is not recorded.
- Only supported KNX function types are exposed to Matter. Arbitrary values, diagnostics, energy readings and every app-specific function are not automatically exported.
- Matter platform capabilities and device limits depend on installed firmware and licensing.
