We received a contribution from Sven G, about checking the temperature in the garage where his dog sleeps with OpenBSD:
I was inspired by the April 2017 article in undeadly.org about getting OpenBSD running on a Raspberry Pi 3B+. My goal was to use a Raspberry Pi running OpenBSD to monitor the temperature in my garage from my home. My dog has his own little "apartment" inside the garage, so I want to keep an eye on the temperature. (I don't rely on this device. He sleeps inside the house whenever he wants.)
If anything seems wrongheaded, please chalk it up to a frothy mixture of enthusiasm, ignorance, stubbornness, and "just-because-I-wanted-to-do-it-this-way-ness."
