It occurred to me that I never answered this. Sorry.
Every 30 seconds, a Tempe unit will broadcast 3 things: the current temperature, plus the high and low temp it's seen over the last 24 hours. According to its own internal clock.
Use cases: I have a Tempe clipped to each paper of ski boots I use. I've been night skiing down to -10F. I keep one on my backpack for hiking. When I hike in and camp in the wilderness, I bring 2 Tempes, one stays outside, the other comes in the tent with me. The watch lets me check either of them at will. None of this is for decision making, or correlating performance data. I have one on my bike because my Garmin records temperature but is affected by my body, and this gets rid of bad data for me.
Tempe costs about $25 and weighs maybe 10g. The battery lasts a year or two.
