The temperature preference can't be too exciting - I can imagine them crunching the data only to discover... most people like 68F or a little warmer! The motion detector is more interesting, since then in principle the device can make guesses about what your schedule implies about you ('works night shift'=='security guard', 'leaves house Sunday morning by 9'=='churchgoer' etc.), but I would have thought that kind of data would leak out of your email and online social.
