MODULE: addition of raspberry pi temperature display

[flewid]

I wanted to display the temperature of the cpu on the rpi 4b, and lm-sensors doesn't work obviously, so here is the file I created. If it's under 75C it prints in green, otherwise it prints in red.

# touch ./modules/29-rpi-temp
# chmod +x ./moduls/29-rpi-temp 
# nano ./modules/29-rpi-temp 

then, this is working for me

#!/usr/bin/env bash

set -euo pipefail
# shellcheck source=./framework.sh
source "${BASE_DIR}/framework.sh"

# Define color codes
RED="\033[0;31m"
GREEN="\033[0;32m"
NC="\033[0m" # No color

temp_rpi() {
    local cpu_temp
    cpu_temp=$(vcgencmd measure_temp | sed "s/temp=//; s/'/°/")
    echo "${cpu_temp}"
}

# Extract numeric temperature value from the formatted temperature string
get_temp_value() {
    local temp_str="$1"
    echo "${temp_str}" | sed "s/[^0-9.]//g"  # Strip everything except numbers and decimals
}

cpu_temp=$(temp_rpi)  # Call the function to get the CPU temp (e.g., "57.9°C")
temp_value=$(get_temp_value "$cpu_temp")  # Extract numeric part (e.g., "57.9")

# Determine color based on the temperature value
if (( $(echo "$temp_value > 75" | bc -l) )); then
    color="${RED}"
else
    color="${GREEN}"
fi

# Print using the framework's print_columns
print_columns "CPU Temp" "${color}${cpu_temp}${NC}"

then just save the file using CTRL-X then 'y' and 'enter' to save.
