Do you get any smoke from the wildfires where you are?

Also see: https://www.uradmonitor.com/direct-data-access/ . It covers your question too.

Thanks guys!

Well there is a curve that shows resistance to alcohol ppm equivalence here: https://www.uradmonitor.com/metal-oxide-voc-sensors/

But please understand that VOC means a mixture of substances and you cannot compute a generic VOC ppm due to the unknown nature of this mixture. Best you can do is to estimate carbon concentration or do equivalence to various substances such as alcohol. In my opinion it is not worth it as it doesn’t bring any new information, you’ll see the same graph shape, only the figures will be different as your approximation function will be linear. You already have the “VOC-AQI” for that.

Sorry guys , this was a severe bug introduced in latest backend update, missed it somehow so far. Problem fixed. Please confirm.

Connecting to the smoggie can be difficult from some devices. When this happen best thing is to try another phone / laptop / etc.

The smoggies can also be configured via USB.

Yes, the smoggie is constantly being improved, more work is being done on the enclosure, please check the website and the FB page , you’ll see some pics on this soon.
