I am running the BME688 in FORCED mode, ULP mode and these are my power consumption measurements:
As you can see is the average power consumption far too high then it should be. When I disconnect the BME688 my Thunderboard EFR32BG22 uses 2.67 microAmpere. Could someone help me with this.

No one that can help me?

I did some work on the 688 in ULP mode connected to a Raspberry PI4 which draws between 2.6w and 3.1w bouncing up and down every 4 to 5 sec (includes an ssh login). Placing an ammeter (on the 25 mA scale) in the power line between the PI and the BME688 (I2C) then running a parallel mode python script (300sec), the meter flicks up to 13mA every 5 min and sits at zero mA the rest of the time.
Hope this helps

The BoschSensortec spec suggests an average of <0.1 mA but as your test shows ULP is very spikey.
