My apologies. I know that this has been discussed (Scott?), but I can't find the topic anywhere. I've searched by title, author, and scrolled through pages of threads. Well, here goes: What are the real-world temperature ranges that correspond to the bars (blue/yellow/red) on the Vitals screen? My battery never drops to the lowest blue bar, but I assume that exists to indicate freezing temperatures since the battery would automatically be heated in that event. My Motor and PEM always start out at the lowest blue bar, but the PEM quickly heats up to maybe the third blue bar. The Motor rarely even gets as hot as the PEM. I've never seen a yellow bar, although I have seen Performance turn red. Anyway, I'd like to correlate my Mac log graphing app displays with what I see on my Vitals screen. Any help or links would be appreciated. Maybe this topic can serve as a focal point for temperature discussions if the existing discussions are in the midst of broader topics.
