That's something I didn't think of... how often the device is polled. Every thirty seconds seems enormous to me. Is that just one data point or a log of all the data points since the previous transmission?

A lot of the finer changes in temps of my ride will be missed entirely just by that alone.

I'll still be just as happy with sticking my arm out the door before I leave to gauge what to wear and how I might perform.

Though I don't know what the use is the OP has for their Tempe, other than to have something that might be a little more local to them than the TV weather report.
