KNX

SPX Server ships two KNX components:

• knx_ip — KNXnet/IP client (talks to a router/gateway)

• knx_ip_simulator — in-memory KNX bus simulator for local testing

knx_ip (KNXnet/IP client)

YAML key: knx_ip

Example model (spx-examples): library/domains/iot/generic/room_controller__knx.yaml

communication:
  - knx_ip:
      router:
        host: knx_gateway
        port: 3671
        route_back: true
      poll_interval: 0.3
      bindings:
        - name: room_temperature
          direction: outbound
          group_address: "2/0/1"
          dpt: 9.001
          read_attribute: "#attr(room_temperature_c)"
        - name: setpoint_command
          direction: bidirectional
          group_address: "2/0/2"
          dpt: 9.001
          read_attribute: "#attr(room_command_c)"
          write_attribute: "#attr(room_command_c)"

Notes:

• Dependency: knx_ip requires xknx in the SPX Server environment.

• Use dpt (for example 9.001) or value_codec (for example bool, uint8) to control encoding.

knx_ip_simulator (in-memory bus)

YAML key: knx_ip_simulator

communication:
  - knx_ip_simulator:
      poll_interval: 0.5
      bindings:
        - name: room_temperature
          direction: bidirectional
          group_address: "2/0/1"
          dpt: 9.001
          read_attribute: "#attr(room_temperature_c)"
          write_attribute: "#attr(room_temperature_c)"
