<p>Migrated comment #1964</p> <p><b>New page</b></p><div>An other nice (maybe the best?) Solution is to install the PWM fan control as a Service...<br /> in this case you are able to restart the Service in case you change some Values for temperature control...<br /> <br /> To do this follow this steps:<br /> <br /> 1st. create a Service file for the x735 ppm service like:<br /> <br /> sudo nano /lib/systemd/system/x735.service<br /> <br /> into this file copy this:<br /> <br /> <br /> [Unit]<br /> Description=x735 PWM Control Service<br /> After=multi-user.target<br /> Conflicts=getty@tty1.service<br /> <br /> [Service]<br /> User=pi<br /> Group=pi<br /> Type=simple<br /> ExecStart=/usr/bin/python /home/pi/x735-v2.5/pwm_fan_control.py<br /> StandardInput=tty-force<br /> <br /> [Install]<br /> WantedBy=multi-user.target<br /> <br /> save &amp; close this file:<br /> <br /> ctrl+o<br /> ctrl+x<br /> <br /> reload the systemctrl deamon:<br /> <br /> sudo systemctl daemon-reload<br /> <br /> Don&#039;t forget to remove any entrys in the /home/pi/.bashrc or if you follow my previous post in the boot_script.sh load this script twice or more often will have no effect to the fan but generate more system load...<br /> <br /> Take care about your file path to the ppm_fan_control.py file and all the other you use in this case... ;)<br /> <br /> after all, reboot your Pi:<br /> <br /> sudo reboot<br /> <br /> Make sure the fan DONT spin at this moment...<br /> If the Fan spin you should check everything twice... Somewhere the script will be loaded at an other place...<br /> <br /> If the fan don&#039;t spin, it is time to enable the new service:<br /> <br /> sudo systemctl enable x735.service<br /> <br /> Now you can check if all this stuff will work by using<br /> <br /> sudo service x735 start | stop<br /> <br /> after reboot the fan should spinning...<br /> <br /> If you change some temperature values in the pwm_fan_control.py it will take effect after save the file and restart the x735 service:<br /> <br /> sudo service x735 stop<br /> sudo service x735 start<br /> <br /> that&#039;s all...<br /> Good Luck!
