Hi!
While communicating with a monitoring unit, I get some hex values
representing degrees celcius from its probes. The values can be
something like '19' or '7d'. To convert it to int, I do the following:

The problem is negative values. If the unit returns the hex value 'e7',
it means -25, but python says it's 231:

int('e7', 16)

Does anyone have a clue a to what I need to do?

If you want a special interpretation of the value, you'll have to
calculate it.
