The controller is annoying and changes completely every 6 months, and for home I use basically none of its features beyond configuring the AP. Virtualy all the issues I’ve had with Unifi APs were controller bugs, telling the AP firmware to do stupid things when it could have done literally nothing.

That said, I have some concerns that the OpenWRT AP firmware is not as optimized as the Unifi firmware is for that specific hardware. Mostly for wireless performance, but I also don’t want to hit some weird CPU bottleneck.
