Could you please tell me how much seconds t takes for TPGH in force mode considering also the heater time to be ready and the total average current in this time window?
In Ultra-Low-Power mode (ULP), the TPHG measurement takes ~2s with a current of ~12mA then the sensor remains in sleep mode for the remaining ~298s, so the total average current over the 300s cycle is ~0.09mA.

ULP:
What do you mean about BSEC. Is it a fw library supplied by bosch?
From what I know since I understood the sensor is still active in sleep mode, my MCU has simply to send a request every about 5 minuts but what you mean with :
"BSEC uses timestamps as input/output which tells you when the next measurement is needed"
Yes, BSEC is a SW library that you can find here. The library doesn't run in the sensor but in an external controller, typically the MCU connected to the sensor (the ESP32 is supported in the default package). This library processes the raw BME680 data over time and converts raw sensor signals into the IAQ index, etc. You need to pass a timestamp to BSEC together with the raw sensor data, and together with the outputs you have enabled it will return the timestamp it wants for the next sample.
