As the old thread is locked I'd like to raise this one again.
My Edge 1030 reads low temperatures below what is correct. I have tested this against a digital thermometer with K type thermal sensors in a static environment. (Winter and the fridge)
At three Degrees Celsius the 1030 reads below Zero. At five degrees (in the fridge) it read 1.2C
It must be difficult to accurately read the temperature in the unit, but why can't Garmin add the Tempe sensor to the devices this supports. My Vivoactive 3 supports the Tempe, but not the Edge 1030.
Personally, I make great use of the temperature reading during winter rides as an indication of possible ice on the roads and would much appreciate an accurate reading by any means.
