The UDM and UDM-Pro force you to set up a UI.com account, and cannot be used with external Unifi controllers like one you might run on a server, PC or cloud key (Ubiquiti's management software on a Power over Ethernet powered dongle, does not require a UI.com account).

The UDM and UDM Pro are the controller, and you can disable all of the cloud nonsense after initial setup.

Wow, that sucks. So you HAVE to create a cloud account to be able to disable it later?

[JamesSwift]

You can disable on the UDM but I don't believe the UDM pro allows you to. Thats just what I've heard though, so might not be accurate.

The UDM Pro does allow it. I've got one, and all of the cloud stuff is disabled.
