Typically a site will be a physical subnet - but you can add multiple hubs to a site that are located on different subnets - as long as each subnet has an active internet connection. Each site requires at least one hub that will be configured for the hardware type installed at the site. A hub is limited to 32 doors per controller type.
Notes:
- The site defines the hardware type to be used.
- Every system needs at least one site.
- The hub is claimed and assigned to the site.
- Multiple hubs can be assigned to the same site (if more than 32 doors are on the system) or if the controllers are in different physical locations or subnets.
- If adding multiple hubs to the same site they must be of the same hardware type.
- Multiple sites (and multiple hubs) must be used if controllers will be located in different geographical timezones.
