Wifi System for Home -> Wifi Controller?

[Lord of nothing]

Hi
I need 4 Hotspots for each floor. I also will use my Wifi Phones from Ascom (if I get the Virtual PBX Working  ).
I still research what kind of Protocols the Phone need. The Phone require atleast:

IEEE 802.11e-2005 or 802.11e is an approved amendment to the IEEE 802.11 standard that defines a set of quality of service (QoS) enhancements for wireless LAN applications through modifications to the Media Access Control (MAC) layer.
   In addition to the Power Save Polling mechanism, which was available pre-802.11e, new power save delivery and notification mechanisms have been introduced in 802.11e. APSD (automatic power save delivery) provides two ways to start delivery: ‘scheduled APSD’ (S-APSD) and ‘unscheduled APSD’ (U-APSD).

Sure there is a "White List" with Hotspots but on there not the newest Hotspots are. 

So do I need a Wifi Controller to Mange all Hotspots?
I do a Quick Research on our IT Distributor Webshop what the offer and the price just for the Controller are  ... (exclude Tax)
LANCOM WLC-4006+ 639€
NXC2500 385€
HPe Aruba 7005 940€
TP-Link Claim to have a Free Software for that who run on a Client OS (who is no problem).

What I definitely not want is a Cloud s .

What about ubiqity unify AP's , the controller is free.
And can even run on a Raspi3

The Unify AC Pro seems nice

If you're network savvy, I would recommend using Mikrotik with their CAPsMAN system. Cheap, amazingly reliable, and easy to setup after you get through the steep learning curve.
