It is possible to define a set of roles you want to distinguish at backend side. One node can own one role which it will announce via alfred inside the mesh. This will make it easier to differentiate nodes when parsing alfred data. E.g to count only normal nodes and not the gateways or servers (nodemap). A lot of things are possible.

For this the section roles in site.conf is needed:

roles = {
  default = 'node',
  list = {
    node = 'Normal Node',
    test = 'Test Node',
    backbone = 'Backbone Node',
    service = 'Service Node',

The value of default is the role every node will initially own. This value should be part of list as well. If you want node owners to change the defined roles via config-mode you can add the package gluon-luci-node-role to your Then, you can select one of the defined roles from a dropdown list where the right-handed value is the one which is displayed and the left-handed key the one which is configured into the system.

The role is saved in gluon-node-info.system.role. To change the role using command line do:

uci set gluon-node-info.system.role="$ROLE"
uci commit

Please replace $ROLE by the role you want the node to own.
