The `tradfri` component supports for the IKEA Trådfri (Tradfri) gateway. The gateway can control lights connected to it and Home Assistant will automatically discover its presence on your network.

For this to work, you need to install a modified lib-coap library.

<p class='note warning'>

This component does **not** work on Windows, as the modified lib-coap doesn't exists for Windows.

If you are using [Hass.io](/hassio/) then just move forward to the configuration as all requirements are already fulfilled.
