Thank you - that's useful information!
Related to the magic offsets, I noticed that the value read from the sensor
was always lower than the value written. However, it doesn't appear to be
a constant difference (I see about 15 for most values, but only 5 for the
minimum). I think that it's OK to keep the higher value - it'll mean that
we run the fans slightly faster. The CPU temperature on my E250 doesn't
reach the minimum threshold where the fan speed actually increases, so I
don't think that this will have any impact.
The GPIO values there helps to see what values I should be checking for too.
It would be good to merge this with the current code, but I only have an
E250 to test on, so I'll need to find a volunteer.
Regards,
Julian
