Hello!
I was trying to install omv sensors... after trying I realized that I will need to change some things.
After get it working I forked the repo and apply some changes to make it works with omv 2
You can see the repo here: https://github.com/zalito12/omvsensors
I'm thinking about make some new changes as add locales, add "actual" temperature, more fans... If I have time I will try.
Make me know if I have made something wrong, I changed differents files and may be I forget to add some of the changes.
