Downgrading Unifi APs from 5.43.43 to 4.3.28

Shortly after I upgraded my Unifi access points from 4.3.28 to 5.43.43; I started getting timeout issues. Not all devices, but some; the Raspberry Pi driving our DAKboard, and both our Netatmo air quality sensors.

In addition to monitoring the CO₂ level, I’m also automatically ventilating the space when the air quality gets too bad.
