Put the command line in the /etc/rc.local file: （'''Default''') vi /etc/rc.local <source lang='shell' line highlight="21">#!/bin/sh -e## rc.local## This script is executed at the end of each multiuser runlevel.# Make sure that the script will "exit 0" on success or any other# value on error.#1# In order to enable or disable this script just change the execution# bits.## By default this script does nothing.

Use crontab to add a timed task. For details, please refer to [[How to add crontab job]]. ==For DietPi=='''install''' sudo apt-get install -y python-smbus python python3-rpi.gpio sudo apt-get install -y pigpio python-pigpio python3-pigpio git git clone https://github.com/geekworm-com/x735-v2.5 cd x735-v2.5 sudo chmod +x *.sh sudo bash install-dietpi.sh echo "alias x735off='sudo /usr/local/bin/x735softsd'" >> ~/.bashrc sudo reboot PS: according to the customer feedback, the above shell script is also work with Citadel, please test yourself, run thanks! ==For Volumio 3==Test the following commandsscript base on the 'Volumio-3.175-2021-12-13-pi.img' The default username and passpword are both 'volumio' '''install''' # Enable SSH Visit 'http://volumio.local/dev/' to click 'Enable' button to enable SSH  # install software and tools via SSH window

5. '''Test safe shutdown'''

At this time, Q: What are the fan is still not rotating, we need credentials to continue to install the pwm fan control scriptSSH into my Umbrel?

We can manually run A: ssh host is '''umbrel.local''' (or ssh <'''local IP address''' of your Umbrel>). The default user name is '''umbrel''', and the following commands:default password '''moneyprintergobrrr''' <pre>  sudo apt-get update sudo apt-get install -y python-smbus python pigpio python-pigpio python3-pigpio git wiringpi sudo apt-get install -y python -rpi.gpio python3-rpi.gpio rpi.gpio git clone https:/home/pigithub.com/geekworm-com/x735-v2.5 cd x735-v2.5 chmod +x *.sh sudo bash install-mynode.sh echo "alias x735off='sudo /usr/local/bin/x735softsd.sh'" >> ~/pwm_fan_control.pybashrcThen sudo reboot If you fail to reboot, please unplug the power directly and restart;</pre> ''' PWM fan control''' The script is installed successfully and the fan starts to run '''Test safe shutdown''' x735off* Please run 'x735off' to shut down or press the on-board button switch to shut down. <span style="color:red;">DON'T run the 'shutdown' linux command to shut down, otherwise the power of x735 fan will start workingnot be shut down.</span>* press button switch 1-2 seconds to reboot* press button switch 3 seconds to safe shutdown,* press 7-8 seconds to force shutdown.

But we hope that the script can be executed automatically when the Raspberry Pi board boots, we can use crontab system command to achieve it'''uninstall''' . please refer to the following/uninstall-mynode.sh

6==For Version 2. How to start PWM fan when pi 4 boots1 or more low version==

sudo crontab Please refer to '''[http://www.suptronics.com/miniPCkits/x735-ehardware.html Hardware]''' and '''[http://www.suptronics.com/miniPCkits/x730-software.html Software]''' and read them and follow the instructions before ask any questions, thank you!

[[File:Crontab-step1The safe shutdown script is same with X730.png]]

Add a line at the end of the file that reads like thisgit clone https://github.com/geekworm-com/x730-script

@reboot python /home/pi/x735cd x730-v2.5/pwm_fan_control.pyscript

Please note the path of this #Setting fileattributessudo chmod +x x730.sh

[[File:Crontab-step2#Install the scriptsudo bash x730.png]]sh

Save and exit (CTRK + O and ENTER #Setting up the command to save it)turn off X730 from software printf "%s\\n" "alias x730off='sudo x730shutdown. In nano editor, you do that by hitting CTRL + X, answering Y and hitting Enter when promptedsh'" >> ~/.bashrc

== How to read #Reboot the fan RPM?==Raspberry Piplease refer to /home/pi/x735-v2.5/read_fan_speed.py, and this is only show how to get the fan speed every second, run the following command. sudo python /home/pi/x735-v2.5/read_fan_speed.pyreboot
