CO2 Sensors that work with Openhab

I remember there is another site that has comparisons of 4-5 different sensors, but could not 123 find it back.

@marcel_verpaalen, any chance you remember which sensors were tested / compared? Would be highly interested in having a look at the comparison as well / do some search for the site.

Update: You mean this thread?

Yess that was the one.
As said, I now use sensair S8 and works quite good.

Thanks.

Will either go for this one or the SCD41 (looks even a bit smaller).

Does the S8 involve my calibration? Or is it factory-calibrated and just does it’s job?

I did not do any calibration that I can recall. But it been a long time ago that I activated the device.

In order not to overload this post (which I owe good information) I created this one: Tuya air quality monitor via Zigbee2MQTT.

I have a binding for AirGradient which is also an option: AirGradient API Binding
