==How to setup script??==1. Once you have logged into your Raspberry Pi from the command line, run the following commands sudo apt-get update sudo apt-get '''install python-smbus sudo apt-get install pigpio python-pigpio python3-pigpio'''

2. Download script and some sample code.Assuming your system is updated, add these packages: sudo apt-get install -y python-smbus python sudo apt-get install -y pigpio python-pigpio python3-pigpio git git clone https://github.com/geekworm-com/x735-v2.5.git 3. Setup script.

sudo chmod +x x735-v25*.sh sudo bash x735-v25install.sh printf "%s\n" echo "alias x735off='sudo x735softsd.sh'" >> ~/.bashrc 4. Reboot

5. '''Test safe shutdown'''

At this time, the fan is still not rotating, we need to continue '''How to install make the pwm fan control scriptrun automatically after booting?'''

We can manually run There are two ways to achieve it;1. Put the following commandsline at the end of .bashrc file:（Default) cd ~ python nano ./x735-v25/pwm_fan_control.pybashrcThen copy the x735 fan will start workingfollowing line to .bashrc file.

But we hope that the script can be executed automatically when the Raspberry Pi board boots, we can use crontab command to achieve itpython /home/pi/x735-v2. please refer to the following5/pwm_fan_control.py &

===How NOTE: Maybe you need to start PWM fan when pi 4 boots===modify the file path if you use other OS.

In this way, this line of command will be executed automatically when the user logs in; 2. 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 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 crontab chmod +x *.sh sudo bash install-edietpi.sh echo "alias x735off='sudo /usr/local/bin/x735softsd'" >> ~/.bashrc sudo reboot

[[File== For myNode OS and Umbrel ==About myNode, please refer to http:Crontab-step1//www.png]]mynodebtc.com/

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

[[FileQ:Crontab-step2.png]]What are the credentials to SSH into my Umbrel?

Save and exitA: ssh umbrel@umbrel. In nano editor, local (or ssh umbrel@<IP address of your Umbrel>). The password is the same as your Umbrel's password. If you do that by hitting CTRL + Xhaven't set a password yet, answering Y and hitting Enter when promptedthe default password is: moneyprintergobrrr.
