@Dimitar(Shelly team) if it helps:
I have only Unifi AP's
Here the report When Shellies have problems to connect as requested by DD:
Shelly Vintage

Model UniFi AP-AC-Pro / untergeschoss

Board Revision 26
Model UniFi AP-Flex-HD AP Büro

Last Activity Just Now
Uptime 7d 21h 24m 37s
Connected AP untergeschoss
ESSID solysombra
If the Shelly is connected to the AC-AC Pro, the Shelly looses the WiFi connection after a few hours.
All other clients at these AP work fine.
If i force the Shelly to connect to the AP Flex HD it is reachable without problems. See here :
