  • I’m not sure why you’d NOT want a battery powered one, because as you say, the batteries last years, and a USB powered one would waste much more electricity over time, but I digress.

    If you have any mini SoC boards or ESP32 devices laying around, you can get dirt cheap 2-pin external temp sensors. Works on anything with a GPIO pin out that supports simple I/O.

    Anything you find that is Zigbee by nature will be battery powered, however, you might be able to find a device with a different purpose that happens to have temp sensors that export data you could monitor.









  • Kanji is a derivative of older Mandarin character sets. That’s why they look alike. Modern Kanji is of course dissimilar, but the glyphs still look similar, so unless you know one or the other deeply, I wouldn’t find it odd for people unfamiliar with either to be able to tell some of them apart.

    The example characters you’ve provided do look fairly similar to me, though I’m somewhat familiar with Kanji and can normally tell the difference.
