I haven't seen any mention of an onboard temperature sensor. They do
have their own proprietary breakout module with
temperature/humidity/light[1]. All the references I've seen are to
putting in a simple variable voltage temp sensor like the TMP36[2]
attached to one of the IO pins and just reading that. But the Xbee is
actually quite versatile with ~10 digital/analog I/O pins and even two
PWM pins. It would be nice to expose that in owfs as there are plenty
of projects where that would be plenty.
