Recommendation for a Wi-Fi 6 AP that also supports 802.3at PoE?

Yes, but you only need one supported device, don't you?

What happened to the Ubiquiti suggestion? I have two Unifi 6 Lites here and am pretty happy with those. Nice and compact design, and relatively inexpesive. Well known (aka old) MT7621 SoC. Lousy old 2.4GHz radio. But the 5GHz WiFI 6 radio is fine, and all I care about. Only using 2.4GHz for IoT stuff.

Only power option is 802.3at No power connector. Or connector at all except for the single ethernet port. But who needs more? If you want to power it separately then use an injector.

I'm powering them from a ZyXEL GS1900-10HP switch also running OpenWrt. Ports lan6 and lan7 here:

That's pretty typical consumption. FWIW, the lan8 port is an RPi4 with a gazillion USB devices. Eh, make that 4. But anyway. It doesn't consume that much on its own.
