[KNX/EIB](http://www.knx.org) integration for Home Assistant allows you to connect to a KNX bus. The component requires a local KNX/IP interface like the [Weinzierl 730](http://www.weinzierl.de/index.php/en/all-knx/knx-devices-en/knx-ip-interface-730-en). Through this it will send and receive commands to and from other devices to the KNX bus.

There is currently support for the following KNX Data Point Types

 - Temperature: KNX Datapoint Type 9.001 - °C - 2 Byte Float
 - Speed(Wind Speed): KNX Datapoint Type 9.005 - m/s - 2 Byte Float
 - Illuminance(Lux): KNX Datapoint Type 9.004 - Lux - 2 Byte Float
