Hager
Hager domovea basic
KNX visualization server that exposes selected building devices to Matter over Ethernet.
- Product type
- KNX to Matter bridge
- Model / SKU
- TJAS671
- KNX connection
- Direct KNX TP; KNX ETS or Hager KNX Easy installation
- Matter connection
- Ethernet
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
- 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)
- Matter export is limited to 128 KNX devices; the 500-device domovea capacity is a different limit.
- A Matter controller is required; domovea is not a Matter controller for importing native Matter devices.
- domovea groups and automations are not exported.
- The documented export list is narrower than domovea's own visualization features; color lighting and other advanced functions require separate verification.
- This record applies to TJAS671, not older TJA670 or first-generation TJA450 servers.
- Exact TJAS671 family documentation and the CSA domovea basic certificate confirm the bridge. Functions must also be supported by the receiving app.
