for ubiquiti unify devices a cloud controller is needed, or you can install the software on a computer. the operation is then possible via the gui (even if you are not on site) the oldscool CLI I never needed with these things but look at some tutorial on youtube how these things work are really super simple and user friendly. but just a different strategy behind it than with the better known products. (I use them in the company because I can manage the network from anywhere via the cloud key in every branch).
