API for retrieval of information under Vera's "Location" tab

Vera has a number of user-specified settings under it’s “Location” tab, such as:

Timezone
Temperature Format
Geo-Location

In my plug-in, I’d like to access some of this data (Temperature Format, and Geo-Location in particular).

What luup API do I use to read the location information?

For things like Geo-Location, it displays my [Localized] City name. What format(s) is this available in internally? I’ve seen both the Localized name (like “Reno”) as well as Lat/Long values in the UI, but generally it’s the Localized name.

Also, is there a “normalized” value we should be returning for Temperature controls?

eg. Always return degC or always return degF for compatibility across devices?

For those inerested, it looks like MCV added these to the luup Wiki doc over the weekend:
