This looks like an interesting project: https://learn.pimoroni.com/tutorial/sandyj/enviro-plus-and-l...

This sensor also looks good: https://shop.pimoroni.com/products/adafruit-sgp30-air-qualit...

Thanks for the link, already ordered the other sensors. Looks like SGP30 isn't quite as easy to use with ESPHome right now, so something to upgrade to within a year. Its really amazing how great the ecosystem is with ESPHome, I was always a bit scared buying the chips and getting really DIY with the likes of Arduino but this is no more difficult than most other tech.
