Only reads GPIO when user is sudoer #76
Comments

This is not an issue with the plugin, and there is nothing I can do about it. Check this for more information: |

Hello, |
|
It is not getting the temperature from the plugin, probably because it can not find the scripts, or the access for the files are not correct: Check if the files were copied, the default installation would be something like this: It should not need to run as pi, but again, if you just flash the default image it's going to just work, I suggest doing that. If you don't want to to this, find the installation files, check that they are there, fix the permissions, test the scripts by using: sudo python /home/pi/oprint/lib/python2.7/site-packages/octoprint_enclosure/getDHTTemp.py 22 4 Also, you can just add a simple LED to raspberry pi GPIO and test a simple output, to see if it's working. |

Thank you for your answer the files are here, they are in /home/MYUSER/OctoPrint/venv/lib/python2.7/site-packages/octoprint_enclosure
and the script works fine, even without sudo (I just run python getDHTTemp.py 22 4 , it returns temp / hum)
I guess the call to the script expects the path to be /home/PI/OctoPrint/venv/lib/python2.7/site-packages/octoprint_enclosure,right?

Actually it does not, it should automatically find the file where the plugin is installed: Enable the debug mode on the advanced part of the plugin, it will log where it thinks the files are and more info to trouble shoot. Reboot raspberry pi, send me the entire log after you start getting the errors again. |

I forgot that you need to manually change one line on init.py file line 41 change it to false, save, restart, and do it again.... Just change using nano for example: nano /home/YOURUSER/OctoPrint/venv/lib/python2.7/site-packages/octoprint_enclosure/init.py |

The sudo Python … can’t work on my system because my user as password enabled for sudo.
Where in the code can I change the command to remove sudo ?
Thanks in advance

Just do a search and replace "sudo python" to "python" on this entire file.... |

Nailed it! thanks for your help. might be worth documenting in case some other geek does its own octoprint install

I'll create a "force sudo" checkbox on the advanced settings on following releases, if you uncheck it would fix issues like this by not trying to use sudo. |
|
I think that would be perfect
Thanks again for your support!

I just finished re-writing most of the plugin and implemented this requested feature, tested 95% of the plugin. If you want to test it out uninstall the current plugin, go to the plugin manager, select get more, and where it says "from URL" use the development branch: https://github.com/vitormhenrique/OctoPrint-Enclosure/archive/dev.zip More documentation here: I'll push this to production after more people test it out. |

Excuse me I have similiar problem with DHT11 - "sudo python" isnt working but "sudo python3" return temp and humidity. Changing init.py file and replace python to python3 will be helpfull?! Yes, IT WORKS! Thank you for advice! |
Hello,
Issue is the following: by default the GPIO is accessible only by sudoers, hence if the user running octopi is not a sudoer with "no password" (which is not very security friendly) the GPIO read doesn't work.
Regards,
Thierry
