 ### Manage Devices
 
 An automation setup needs to access several different devices to be able to communicate with sensors and actors (e.g. an USB Z-Wave modem). These are by default not accessible to docker containers, docker swarm also does not provide a default way to grant access to them. Docker uses cgroups to manage device access though. This enables us to grant the correct cgroup permissions when a container launches. The script offers a menu entry to install the necessary files and rules on any connected node. A second entry then allows to setup links between containers and devices.

To make the script aware of the new device (and have an entry in the menu) simply extend the constant `USB_DEVICES` in the `building_manager.py` by a new entry using the device name as the value.
