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"
Love the evolution! How are you measuring the power consumption of your devices? I’d be interested in profiling my build as well.
Probably the easiest way. It’s plugged into a smart plug with energi monitoring.
I use a device similar to this. Pretty useful and handy.
