Just finished my second version. This time in a 3D printed enclosure and a Bosch BME680 (with official Bosch library). So now I can read CO2/Temp/Humidity/Pressure/VOC/IAQ. The BME680 can also act as a smoke detector. I tried it with setting a piece of paper on fire. The IAQ readings immediately went up to over 400 (range 0-500),
One can do the (WiFi) setup via a WiFi access point to fill in the parameters for WiFi/Homey and a MQTT client. Still need to calibrate the CO2 sensor by the way. !
