Do you think a humidifier could do this, oR a very cold attic?


the rise in temperature can do it when the furnace comes on

I don't know how that's possible. All the home smoke detectors
I've seen use photo sensing or ionization to look for smoke and
don't respond to temperature changes.

Some do respond to temperature changes.

A humidifier shouldn't be tripping it
either, it just puts humidity in the air.

But badly designed ones can produce steam.

However a cold attic with missing insulation that results in
a cold ceiling and a cold smoke detector and a humidifier
turned up too high could result in moisture condensing
inside the smoke detector. And water and electronics
don't mix well.
