mqtt:
  base_topic: knx2mqtt
  server: 'mqtt://localhost'
knx:
  ip_address: 192.168.1.145
  port: 3671

  log_output:
    - console

Payload:

id: a unique string for you
individual_address: the configured Individual Address of your KNX device,
group_address: the Group Address your device send data to
dpt: the Data Point Type of your device. For the supported DPTs please refer to knx.js

{
    id: 'uniqueStringId',
    individual_address: '1.1.1',
    group_address: '1/0/0',
    dpt: 'DPT9.004',
}

Payload:

This payload must be sent as a string not as a JSON object.

You can subscribe to this topic in order to receive data from the device.

In this topic are sent:

{
  type: 'device_connected', 
  message: {
    friendly_name: 'uniqueStringId'
  }
}

{ 
  type: 'device_force_removed', 
  message: 'uniqueStringId'
}

This work relies on the awesome knx.js library

This work is inspired from the awesome work of Zigbee2MQTT.
