Question about Ubiquiti Us-8-60w

Everything works fine for me, but I don't operate the switch individually, I use the security gateway together with a cloud key controller, where I have even more options where I can view and configure. You can't do much on the switch itself, there are also various functions and evaluations missing. I only got these functions by integrating a controller. The controller gave me the following functions: Overview, devices, end devices, statistics and more Under the point more, you have more things like insights, map, events, alarms, hotspot, settings, etc.
The Switch alone can't do that, but together with a controller it can.

Yes and no. A USG and an active Unifi instance are required (e.g. Unifi CloudKey). So the device alone can't do it.

Thanks for the answers!
I plan to use the switch with a USG and the Cloud Key (Gen. 1). The latter also because no control SW has to be installed (if you don't have a network you can't download any SW to get a network, it's always the same problem).
My goal is to always have a low ping on my PC with a relatively small bandwidth, even if the total network load should be in the border area.
I have only heard good things about Ubiquiti products and that they work very well together.
Then everything should fit!
