Configuration

Overview

XKNX is controlled via a configuration file. Per default the configuration file is named xknx.yaml.

The configuration file can contain three sections.

  • The general section can contain:
    • own_address the individual (physical) address of the XKNX daemon
    • rate_limit a rate limit for telegrams sent to the bus
    • multicast_group to override the default multicast address (224.0.23.12)
    • multicast_port to override the default multicast port (3671)
  • The connection section can be used to specify the connection to the KNX interface:
    • auto for automatic discovery of a KNX interface
    • tunneling for a UDP unicast connection
      • gateway_ip (required) sets the IP address of the KNX tunneling interface
      • gateway_port (optional) sets the port the KNX tunneling interface is listening on
      • local_ip (optional) sets the IP address that is used by XKNX
      • route_back (optional) When True the KNXnet/IP Server shall use the IP address and the port number from the IP package received as the target IP address or port number for the response to the KNXnet/IP Client (for NAT / Docker). Default: False
    • routing for a UDP multicast connection
      • local_ip (optional) sets the IP address that is used by XKNX
  • Within the groups sections all devices are defined. For each type of device more then one section might be specified. You need to append numbers or strings to differentiate the entries, as in the example below. The appended number or string must be unique.

How to use

Use the config attribute when initializing XKNX to spefify a configuration file:

xknx = XKNX(config='xknx.yaml')

for device in xknx.devices:
    print(device)
