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