"Avoided water damage"

I had a RuuviTag in my house's boiler room. One day I noticed suddenly increased air humidity levels and went to see what's going on. Found a leaking water pipe!

“Interesting history logs”

Every morning my dad checks temperature logs from his phone to see how the weather was at night.
