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'''

We can manually run the following commands: python ./x735'''read-fan-v25/pwm_fan_controlspeed.py'''Then the x735 fan will start working sudo python3 read_fan_speed.py

But we hope that the script can be executed automatically when the Raspberry Pi board boots== For myNode OS and Umbrel ==About myNode, we can use crontab command to achieve it. please refer to the followinghttp://www.mynodebtc.com/

6About Umbrel, please refetrto https://getumbrel.com/, we test it base on 'umbrel-os-v0.4. How to start PWM fan when pi 4 boots.img'

sudo crontab We tested umbrel v0.4.16 on Apr. 18th, 2022 base on 'umbrel-eos-v0.4.16.img'

Choose "1" login to mynode teminal via Putty or Xsheel tool, the default user name is `admin`, password is `bolt`, then press Enterrun the following command:

Add a line at Login to mynode teminal via Putty or Xsheel tool, the end of default user name is `umbrel`, default password is `moneyprintergobrrr`, then run the file that reads like thisfollowing command:

Please note Q: What are the path of this file.credentials to SSH into my Umbrel?

[[FileA:Crontab-step2ssh host is '''umbrel.png]]local''' (or ssh <'''local IP address''' of your Umbrel>). The default user name is '''umbrel''', and the default password '''moneyprintergobrrr'''
