Hi,
On BSEC documentation, I can find this:
Static IAQ: Unscaled indoor-air-quality estimate
Breath VOC: Breath VOC concentration estimate [ppm]
CO2 equivalent: CO2 equivalent estimate [ppm]
Could you detail these data please?
I don't understand what data static IAQ can reveal?
Breath VOC will be superior to 0 only when there are people close to the sensor?
Thanks,

The bVOC-equivalent output is not binary (0/1) if the mixture is detected, but an estimated VOC concentration output (in ppm) based on the static IAQ output and lab tests (including with the b-VOC mixture).

Since fire emits CO2, CO2eq would be very high in case of fire?
The BME680 is a TVOC sensor, not a CO2 sensor. Therefore any BSEC output will always be proportional to the total VOC concentration detected by the BME680 in its environment, not to CO2.
