What is OK for an outdoor smoker, is not OK for an indoor wood fired
stove, a much more dangerous device.

True, if you make a mistake with the program, you may never find
out!

However, about everything that can be sensed with electronic sensors
can be fed into a controller and acted upon or at least sound an
alarm. So, on a wood stove you could monitor temperatures, carbon
monoxide, or any other relevant conditions that you might want to
monitor on a wood stove. Controls checking and acting on conditions
hundreds of times per second can catch and correct a problem better
than a person can.

I share Iggy's concern enough that I don't run the stove when I'm
away. In midwinter I came home from work to a 50F house, the setting
of the electric backup.

The control I was considering would have closed the air inlet on the
door as the stove came up to temperature. I didn't add it because I
don't want any possible interference if the fire runs away and I need
to shut it down.

After Thanksgiving I let the house cool to measure the rate vs
outdoor temperature. At 2AM on Saturday the smoke alarm blasted me out
of bed, to the smell of something electrical that had overheated. I
rushed around checking all the electronics, found nothing warm,
rechecked them twice anyway. Then I noticed that the smell was
strongest near the hallway radiator, which hadn't been disassembled
and vacuumed out in a long time. I had forgotten about the backup
setting. The radiator had turned on, and the alarm and hot plastic
smell were from rug fibers in it.

What fun!

I woke up to some fun this morning. -=No water=- The pump pressure
is up but the lines are frozen. I put a heater in the pump house (the
light had burned out, allowing the freeze?) an hour ago but no joy
yet. I'll put it in the crawlspace in a few minutes and see if that
does it. sigh

It has been 10 or 11F here two days in a row. The lowest I've seen
here before is 17F, and my outside line burst 8 years ago. I have
insulated the exterior pipes and shut them off for the winter now, so
this is the first problem I've had, and the first time losing water.
There's a shutoff valve for each inside and outside lines.

Crap!
