This was an interesting experiment... I fixed the TEMPE logic to handle 16-bit signed integers so it could handle sub-freezing temps and then gathered EDGE 1030 (device) -vs- TEMPE (external sensor) temperatures when both were in the freezer (for an hour) and then both out on my patio here in Orlando in temps in the high 80s. I logged the temps in the Device's LOG file so I could plot them.
The main reason I did this was to calibrate the offset I needed to apply to my TEMPE. Turns out, at about 4F, my TEMPE reads only about 1F more than my EDGE 1030. Close enough. I should have recorded a little longer to allow the EDGE to reach steady state and see how close the EDGE ended up -vs- the TEMPE as they warmed back up.
