> BME680 and BME688 are hot garbage. I agree 100%. What they measure (which is already very non-precise), only vaguely correlates with air quality and there are many factors that would throw off the readings. Reading from their reference manual, one can already see from all the complicated expressions (regression) and numerical factors that they tried too hard to come up with something that looks like an air quality metric.
