The result of this process is that the air purifier boosts when the air quality inside drops.

I feel like that is something that doesn’t or at least shouldn’t require a string of IoT devices, apps, wireless communication and hubs. Why not leave all of that out and just attach an air quality sensor to the air purifier and a small LCD to adjust the settings?

The light in my hallway turns on automatically when I walk past. No cloud, no HomeAssist, no WiFi, no Zigbee, no apps, no batteries to change. Just a motion sensor hardwired to the light fixture. Hasn’t failed me once in the past ten years. Works great even if the network goes down.

AQ sensors add cost. I've also never seen a reliable AQ sensor on a air filter. I have several Coway which go into turbo mode at random times and a couple of others that never go above fan speed 1, even when my dedicated AQ sensor shows elevated PM2.5.

A dumb device without leds/screens/connectivity that I can control with a smart plug via HA is much easier to deal with.
