I have the BME680 raw GAS (=Ohms) values plotted here to right axis and to the left axis a very good SenseAir Sunrise CO2 sensor (+-30ppm)
You can easily see my sleep cycles (the linear increase in CO2 in the bedroom while I am emitting CO2 during my sleep in the night) and the steep drop when I open the window in the morning and before going to bed
How do I convert GAS values to IAQ values with EasyEsp or even better, could the plugin 106 do it for me?

Okay, I actually found a solution to my answer: https://github.com/juergs/ESPEasy-mega_ ... 3/releases
This custom ESPEasy Release does some IAQ calculations and its working with my setup - I will report in a couple of days, when I have enough data, how well it compares to CO2 measurements.

And how well does it work?

You can pretty much see whenever the windows are open because the temp and Gas drop simultanously.

You can see at the highest peak, thats when we went to sleep. Didn't open any window. and over night it slowly dropped. some really short window breaks at early morning 6 and 8 am. then again dropping slowly over the day because no one was home.

Hello,
i had been running these sensors on my Wemos:
im Basis Binary:
Light/Lux - BH1750
Environment - DS18b20
Analog input - internal Battery
Environment - BMP280

My BMP280 broke down and I replaced it with a BME680. But I saw it is not basically supported in ESP_Easy_mega_20211224_normal_ESP8266_4M1M version.

I really tried hard do do the self compiling stuff. But I am stucking somewhere in Atom ....

Does anybody have a better (for dummies, very detailed)) instruction or can someone support me with a compiled bin?

Thanks

The BME680 is included in the TEST_B build, and that has also all plugins from the NORMAL build, so just updating to the latest TEST_B build should get you going, without any custom build actions.
