Raspberry pi throttle

A small program to display status of the raspberry pi an CPU governor.

Example output

user friendly

Status: 0x80000 (conservative)
Status:
Undervolted (<=4.63V): OK
  Freq Capped (>=80c): OK
    Throttled (>=85c): OK
    Throttled (>=60c): Previously
ARM:    Core:   Core Voltage: Core Temp:
600Mhz  250MHz  1.2000V       55.3'C

download

sudo wget  https://raw.githubusercontent.com/Eideen/Raspberry_pi_throttle/master/trottled.sh -O /usr/bin/trottled.sh
sudo chmod +x /usr/bin/trottled.sh

Run without password promt

The following commands, expect that the user running the script is part of the usersgroup, run groups to list your current groups.

manuall

echo "%users ALL=(ALL) NOPASSWD: /usr/bin/trottled.sh" |  tee /etc/sudoers.d/RASP-trottled

Via script

trottled.sh --install

Run

To run continuously use sudo trottled.sh -c

To run once use sudo trottled.sh -1

To run with as logging output use sudo trottled.sh -l

Usage: trottled.sh [-c/-1/-l/-h]
Example: 'trottled.sh -c'

Options:
modes:
  -c, --continuously		Loops the cheack every secound. (for monitoring)
  -1, --run-once        Only run once. (for MOTD)
  -l, --logging         Semi-colom list output (for logging)
  -h, --help            Display this help
Options:
  -i, --intervall                  Intevall in seconds. use ".". Default is 1s, minimum is 0.2s.

  CSV output coloms:
  -1 Counter
  -2 Date/time
  -3 ARM core clock
  -4 Core clock
  -5 Core Voltage
  -6 Core temp
  -7 Throttling (
    0=no throttling,
    1=soft_temp_limit(>=60c),
    2=capping(>=80c),
    3=throttling(>=85c))
  -8 Undervolting (
    0=no Undervolting,
    1=Undervolting)
  Previously is not printet in CSV mode.

Definition

supported OS

• Raspberry pi OS

Add to MOTD

If you like to show the status at loggin, you can use the following command:

sudo echo -e '#!/bin/sh
echo
trottled.sh -1
echo' | sudo tee /etc/update-motd.d/30-trottled && sudo chmod +x /etc/update-motd.d/30-trottled

It is importen that the scipt only run once, or you will be unable to login.
