Air filtration and home assistant

Using homeassistant with a new air filter

As a result of the air quality problems in North America (as with many other palces), I've purchased an additional Coway air filtration product. This one integrates with Home Assistant, which I have been using a lot. I also have a Molekule which is attractive, but which is a controversial performance profile.

I got a smaller Coway unit which expired after just 2 days, almost certainly due to a firmware glitch in the WiFi connection it was making. The original unit died unrecoverably due to this software glitch.

I have replaced is with a beefier
Coway AIRMEGA 400S Air filter. It works like a dream. Make sure you don't have a VPN running when you configure it, or it won't work. This brand is highly recommended from many sources, is very quiet, and seems robust (except for the WiFi issue above). I love that it integrates nicely with Home Assistant so it can be spun up in anticipation of my arrival, for example.

One annoying quirk is monitoring and control for the device can only occur via a cloud-based remote interface. Worse, that interface seems to go down occasionally
