What would be a better idea perhaps would be to control a log burning
stove. Once the flue pipe reaches X degrees open the vents a little.
When the temperature reaches Y close the vents. If the temperature is <Y
then turn a stepper motor to open the stove door and insert either home
fire coals or logs with <20% moisture, close the door and lock the

Of course, perhaps the above is only sane up the end of the second
sentence, perhaps the pi should page the stove engineer to carry out
appropriate maintenance.

If you're lucky enough to have GCH then monitoring the amount of fuel
burnt would be awesome and linking the pi to monitor a carbon monoxide
detector would also be highly desirable (is the former even possible?).

I'll go back to dreaming of a parallel world where I might have GCH.
