Non-conforming power data via hwmon

Hi,

I use the hwmow tree (/sys/class/hwmon/) to read the power consumed by Grace (Grace-Hopper module).
I choose the right hwmon? via power1_oem_info which should be at “CPU Power Socket”.

The problem is that the measurements are not continuous, they look like PWM measurements.

Whatever the Power average interval which is here 1000 ms

Power average: 67.036 W
Power average: 67.036 W
Power average: 0.0 W
Power average: 0.0 W
Power average: 67.047 W
Power average: 67.047 W
Power average: 67.036 W

Any idea ?
Thanks in advance, Hervé
