adding a new sensor about graphs1090

[wiedehopf]

I just left this issue open in case someone else wants to make an PR, as maintainer i have no intention to add arbitrary code for this, my primary goal is for this to work well for a very specific use case.
Adding arbitrary graphs is kind annoying as the html needs to be changed.
I suppose the whole website could be changed using dynamic layouting using javascript.
But again ..... it's doing what i need it to do, maybe someone else wants to work on it and make a PR.

Interested in this as well. I am currently monitoring a USB TEMPer2 via the temper.py script, and your throttled.sh script. If it is possible to add extra sensors to graphs1090, please make it extensible so an i2c sensor like the OP or a USB one like mine can be edited in.

And if it is possible, I would copy the code and implement PoE+ hat graphing as well, since it was easy to add to throttled.sh.
