Error 500 trying a DHT11 sensor

[JJare]

I got this internal server error when I try to add an DHT11 sensor, after installing required gpio dependencies:

Error 500 - Error Interno del Servidor

Something bad happened but it's probably not your fault. Letting the developers know about these issues is crucial to supporting Mycodo. Please submit a new issue on GitHub with the following error traceback (copy the entire traceback):

Can somebody help me?

Thx

I committed a potential fix. Go ahead and upgrade to master and see if it resolves the issue.

it works, thank you very much, but now I'm trying to add a graph with temperature and humidity data and getting another 500 internal server error :'(

This is stating there is no measurement unit degrees Celsius (which is very strange because that's a core unit for the system), which indicates there's probably something wrong with your system. I'd reinstall Raspberry Pi OS and Mycodo and see if the issue persists.

Additionally, none of my systems experienced your original issue, even when I attempted to induce it. I did take that code out though because it was no longer necessary, but it seems your system has some unknown issue, perhaps file corruption, damage to your disk, or something else.

Edit: for everyone opening new issues for this: it has already been fixed. Please do a search before opening a new issue. upgrade to master if you can't wait for the next release.
