On this page, http://nitapps.com/, second app down the top, is a script te get the internal temperature on the n810, and it states, "N810 (and probably other Nokia tablets) also have an internal temperature sensor. Because tablets generate very little heat when idle, you can use this sensor to measure ambient temperature. internal-temp is a command-line tool to read the sensor."

Hope this helps.

Sorry for the late reply but I was out of the country, and had no way of checking internet, maybe besides the Location name, something like Local temp:, maybe?
