Reading stuff like this makes me glad I ditched consumer grade all-in-one stuff and went with a $REAL (feel free to substitute appropriate brand) router and stand alone AP.
Sadly not. You generally have to be very technically inclined to use something like Mikrotik (which is what I'm using) and even the Ubiquiti stuff isn't as easy to use as it could be.
Ubiquiti has a consumer/prosumer brand now called Amplifi. I set it up at my parents' and it was a breeze. It's adapted well to some strange network situations they had. (A long story but they moved in to a place with an ancient audio LAN wired through the home and we explored various configurations of detaching portions of the audio LAN for WiFi backhaul.)
Does Amplifi require some cloud login before you can use it? One of my annoyances recently is that the WiFi providers have an iOS app but require you to log into their servers to configure the thing on your local network.
It's been a couple months since I set it up, but as I recall Amplifi did not require an account to set up your mesh.
It offered an optional "cloud" account system for remote administration (such as giving guest access when you are away or rebooting your mesh from your phone when your guest complains about the network not working, and so forth), but did not require it.
That's good to know and I'll definitely check that out when it comes time to recommend something for some of my less technically inclined friends and family.
Wireless performance isn't great (20$ clunky china routers are usually faster), SXTsq that always slowed down horribly after few weeks of uptime, hAP Lite firmware that died (had to be reflashed from netboot, config gone), many software problems with SXT LTE6 (stopped working after upgrade, still broken after downgrade, mysteriously after hour of flashing various versions it suddenly started working again. Incoming voice call to modem SIM card just breaks connection, and it never fixes itself automatically, you need to manually down/up interface. I now fear touching anything in this installation at all).
