I am not sure if this has been mentioned as a suggestion - but I could not find reference to it anywhere (other than stating that you cannot currently do this). It would be so beneficial to have multiple hubs assigned to one location.
For example - I have a workshop that is a good distance from the main house. Probably around 150 yards away. This is too far for Z-Wave or Zigbee to reach but I do have Ethernet run to the shop with a router set as an access point (giving me seamless WiFi from the house to the shop to all around the property).
Since this is too far for mesh to reach, I purchased another hub thinking that I would be able to add that to the existing location. However, I found out that I have to create a new location and a new hub. Even though all my devices (from the house and from the shop) are all listed together, the hubs are treated as separate entities.
Since the Ethernet connection there is the same as the house (same network), it would be great if the hub could act as an extension of the main hub rather than having to work with multiple locations. This would allow for seamless automation across the property rather than have two disjointed installs. (Like getting an alert with a light or speaker in the house if the temperature for the baby pheasants goes over 85 deg).
