Internet should be public like many other utilities.

Oh sorry! I have three of the STARKVIND model with charcoal filters.

My solution is a bit DIY’d; I use my Zigbee devices with Home Assistant & a Silicon Labs Zigbee/Z-Wave combo stick.

I have a few of their air quality sensors, too! They seem to work pretty well, it does take them a minute to calibrate once they’re plugged in though. I also don’t really have anything to compare them to (other than the onboard air quality sensors in the air purifiers).

Always happy to see more Zigbee-controlled fixtures, love my Ikea air purifiers.
