The knx sensor platform allows you to monitor KNX sensors.

The knx component must be configured correctly, see KNX Component.

There is currently support for the following KNX data point types:

Condition	KNX Datapoint Type	Unit of measurement	Data type
Temperature	9.001	°C	2 Byte Float
Speed (Wind speed)	9.005	m/s	2 Byte Float
Illuminance (Lux)	9.004	Lux	2 Byte Float
Percentage	5.001	%	1 Byte Scaled Unsigned Integer

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

# Example configuration.yaml entry

  - platform: knx
    type: temperature
    address: 1/0/3

  - platform: knx
    name: Wind speed
    type: speed_ms
    address: 1/0/0

  - platform: knx
    name: Lux
    type: illuminance
    address: 1/0/1

  - platform: knx
    name: percent
    type: percentage
