Let’s talk a little about the structure of the E2D system.
...
So a Vertex Cluster is a system made out of up to 25 Vertexes connected to one LAN network. Diferent Clusters will have diferent names, which we call Cluster UID or CUID. So all Vertexes in one Clutser will have the same CUID.
Of course there are many diferent types of buildings, so choose to commission Vertexes, that will be likely to work together, or in the same area to be in the same Cluster. You do not need to fill each Cluster, they might have a lot less devices then 25, try to use common sense when joining them into Clusters.
A Vertex group consists of one or more Vertexes inside one cluster. They communicate with each otherwith peer to peer (server/client) communication. A Vertex controller in a group ‘sees’ (knows only of the existence of) other Vertexes in the same group. Communication between groups is still possible, but may be slower. You can create up to 1 groups. Using groups is an optimization of communication, where you can separate and limit communication between floors, areas, etc.
