The `knx` sensor platform allows you to monitor [KNX](http://www.knx.org) sensors.

The `knx` component must be configured correctly, see [KNX Component](/components/knx).

## {% linkable_title Configuration %}

To use your KNX sensor in your installation, add the following lines to your `configuration.yaml` file:

```yaml
# Example configuration.yaml entry
sensor:
  - platform: knx
    name: Heating.Valve1
    address: '2/0/0'
```

{% configuration %}
address:
  description: KNX group address of the sensor.
  required: true
  type: string
name:
  description: A name for this device used within Home Assistant.
  required: false
  type: string
type:
  description: A type from the following table can be defined. The DPT of the group address should match the expected KNX DPT to be parsed correctly.
  required: false
  type: string
{% endconfiguration %}
