I'm building a new house that made me think about what to do for networking, because there is the possibility to do things pre-wired. I have been using an Ubiquiti EdgeRouter Max with a pair of access points for years. They worked absolutely great, but I rarely take advantage of many of their functions, because I don't have much time and patience to figure out how to configure everything correctly. True, I set this up as 5 years ago and haven't touched it since (which is also proof of its reliability). My first instinct is to stay in the Ubiquiti universe and switch to a DreamMachine, which I've heard is much easier to set up. I could reuse my existing access points and add more / upgrade to WiFi 6 over time. But looking at Eero, it seems that they have a pretty good reliability and features with a much simpler interface. And if HomeKit support ever lands, that just seems like a big bonus. But I think that would completely change the way I set up access points. The Ubiquitous ones make the most sense on the ceiling, but the Eero 6 doesn't support POE, so it would probably make sense closer to the points of sale. The new house is quite large at 3000 square meters, so I think that at least 3 access points make sense.
