Question about Ubiquiti Access Point UniFi 6 Professional U6-PRO

I have purchased several devices from this brand. Mainly because the wifi functionality is well implemented via several such access points. This means that a 'complicated' house can be well covered with wifi. The installation was daunting at first. I would have expected a web interface on the devices. But this is not available. Everything is managed centrally. Of course, the manufacturer wants to lure you into the cloud, or alternatively that you download a stupid app onto your mobile. None of this is acceptable to me. If you want privacy and data protection with devices of this brand, you have to operate an additional controller device so that you can manage the devices. I have implemented this with a raspberrypi and installed the controller software there. + The controller software is really good. Even large networks can be topologised superbly, provided the appropriate switches are installed. + Wlan is superb. - Commissioning, if you don't want to create a data slingshot, is a little awkward at first. Once you have the controller, you can get new devices up and running within 2 minutes. - Controller software is proprietary and must therefore be firewalled.
