We also offer a fully certified commercial product (AirGradient ONE) focusing on B2B (Offices, Schools). Then you have monitors from other companies e.g. Awair, AirThings, Kaiterra, Air Visual etc measuring similar air quality parameters.

We try to set us apart by promoting open data standards, clear data ownership, long lasting products that are easy to repair and maintain. More details on our main website [1].

Well we do a version with multiple uplink technology option and a full SDK[1]. The market is actually quite segmented depending on the final use case. This is IMO mostly because of the price of these devices. The CO2 probe itself is costly especially if metrologically calibrated so if you want one for every room in the school / office / home its not insignificant investment.

I'll include a link to our datasheet [1] as to actually answer the question hoping Im not breaking HN rules.

The IQAir is very nice. There is also the Purple Air monitor.

Totally not a judgement about the quality of it, but it amazes me how the IQAir is only supported via Cloud. Even for this really local information I need to contact some Cloud to be able to get the information into my smart home.

This stuff annoys me a lot.

Yes unfortuntately we see a clear trend among other companies towards walled gardens, closed data and forcing people into subscriptions. We at AirGradient do not support this development and made very clear statements on our website.

You can connect to it via SMB and grab the raw logfiles. It stores them as csv.

Not a friendly API for integrating but you can build from there (I have an air visual pro and I do this)

Thank you. The only info I found was their cloud connection.

I was interested because I wouldn't have to deal with customs in their case, but considering the price and interesting integration, dealing with customs might be better :P

Welcome. Actually, on checking, they've also added a .json file with the latest measurements.

smbclient -U airvisual%PASSWORD \\\\192.168.X.Y\\airvisual -c "get latest_config_measurements.json"

if you want an interactive display. Otherwise there are a bunch of csv files with the archived values, under a time-varying filename like:

202301_AirVisual_values.txt

With format:

Date;Time;Timestamp;PM2_5(ug/m3);AQI(US);AQI(CN);PM10(ug/m3);PM1(ug/m3);Outdoor AQI(US);Outdoor AQI(CN);Temperature(C);Temperature(F);Humidity(%RH);CO2(ppm) 2023/01/01;00:00:03;1672531203;0.0;0;0;0.0;0.0;8;3;22.7;72.8;41;406;

Thanks for digging into the mucks of the quote end quote API. SMB makes me think they were aiming for the commercial market and just repurposed it for home.

I was gifted an air things and had this exact problem. Local WiFi device is useless, stores everything in their cloud and takes forever to load randomly.

I believe this is to support their pollution maps and pollution forecasts. Which makes the high price of the product odd to me.

Vaisala has some air quality monitors, although they seem more oriented towards outdoors use? https://www.vaisala.com/en/products/weather-environmental-se...
