I see a discussion that ended a few months ago, asking about audible alarms for VOC. At that point, it sounded like work on this was still in process.
Generally, I’m looking at the AirGradient ONE indoor kit and am not finding specific guidance on how to set up audible alarms or warnings for any pollutant (e.g., PM2.5).
I would much appreciate links to webpages or forum threads that provide up-to-date guidance on what’s available in this regard, and how to set it up.
