  Love the evolution! How are you measuring the power consumption of your devices? I’d be interested in profiling my build as well.

    I use a device similar to this. Pretty useful and handy.

    Them probably uses a special plugin device in the outlet.

    I have this bash script you can use and have a general overview but I’m not totally sure if I fully understand it and if it’s the whole system’s wattage or only the CPU 🤷‍♂️

    #! bash
    time=5
    sum_1=$(cat /sys/class/powercap/*/energy_uj | awk 'BEGIN { sum = 0; } { sum += $1; } END { print sum; }' "$@");
    echo "before" $sum_1
    sleep $time;
    sum_2=$(cat /sys/class/powercap/*/energy_uj | awk 'BEGIN { sum = 0; } { sum += $1; } END { print sum; }' "$@");
    echo "after" $sum_2
    
    sum_1f=$(printf "%.0f" $sum_1)
    sum_2f=$(printf "%.0f" $sum_2)
    
    final_sum=$(echo "(($sum_2f - $sum_1f) / 1000000) / $time" | bc -l)
    #echo $final_sum | bc -l | xargs printf "%.2f\n"
    
    formated=$(echo $final_sum | bc -l | xargs printf "%.2f\n")
    echo $formated "w"
