If it’s not the humidity it’s the smoke alarm…

Apparently smoke alarms, or at least my smoke alarm, aren’t recommended for use when the humidity is higher than 85%.

With the humidity at 100% outside, and a window fan drawing outside air into my bedroom, my smoke alarm went off just now: I presume this is why, as, fortunately, my house isn’t actually on fire.

What a coincidence! We recently had the same thing happening, our downstairs smoke alarm went off due to a sudden rise in humidity that afternoon. Looking at it I found a sticker saying it should have been replaced in the fall of 2014 (meaning they were installed when the house was built in 2004). So I ordered new ones and replaced them this week. Now we're good for a decade again.

Also spiders. I think spider moving in is what set off the alarm in bedroom
