I was wondering why it appears the official firmware doesn’t support the BME680 even though there’s a spot for it on the boards? Last I saw there was some discussion back in 2022 about this but it seems like it could be a good secondary sensor to use or an alternative.
I had one running with the ESPHome firmware. The CO2 sensor wasn’t accurate at all and other values didn’t match what the stock sensors were showing, so I mostly gave up on it.
