MMM-SystemInfo does not show all values

[xIExodusIx]

MMM-SystemInfo does not show all values, only QR code, CPU usage, Internet (yes), IP address and SSID are displayed, all other values are missing.

Running on MM 2.29
npm 10.8.3
node 20.9.0
Raspberry Pi4
Raspi OS Bookworm 64bit

My bad buddy... the issue is mainly "lack of documentation".
Due that linux is linux and has a lot of flavor... debian, arch, and a lot of etcetera, the command to show some info can differ according to that flavor.
For example, the CPU temperature... you need lmsensors installed, and even whith that get the correct value is difficult because is you CPU has 8 cores is not the same "value" if the CPU has 2 cores.
So, to "fix" that, I added the Command parameters, you can read a bit about that here and you can check a bit more in the code

Below lines work fine on my ubuntu 22.04.

cpuUsageCommand: "top -b -n 1 | awk '/^%Cpu/{gsub(/,/, ".", $8); print 100 - $8}'",

ramUsageCommand: 'free | awk '/Mem:/ { printf("%.1f\n", (($3 + $5) / $2) * 100) }'',

cpuTemperatureCommand: "echo "$(( ($(cat /sys/class/thermal/thermal_zone0/temp)) / 1 ))"",

showVolumeCommand: "amixer -D pulse get Master | awk -F 'Left:|[][]' '{ print $3 }'",

diskUsageCommand: "(df -kh . | tail -n1 | awk '{print $5}')",

on my Raspberry Pi 3 Model B Rev 1.2, 1GB with 4 CPUs on 1 socket with Raspian 13 (trixie) in German language following commands are working fine for me:
cpuUsageCommand: "top -b -n 1 | sed '/average:/s/, /: /g' | awk '/average:/{ split($0,a,": "); print a[4]*100/4 }'", // average CPU load last minute - adjust number of cores (4) to yours
cpuTemperatureCommand: "cat /sys/class/thermal/thermal_zone0/temp",
ramUsageCommand: "free | awk '/Speicher:/ {print (($3 + $5) / $2) * 100 }'", // adjust the word 'Speicher' to your OS language
diskUsageCommand: see above @MsMinutes

remove the backslashes () if you want to run it for testing on your raspberry's commandline instead of MagicMirror's config
