Great, thanks for the tutorial!
Also, very helpful ideas for the expansion. I will, as learning python project, add some kind of storing data as you suggested. And, at some time in the future, email notifications. Raspberry Pi may be a great, low electricity idea for running this non stop, or using chrone in Linux as you mentioned.
It is amazing, how little code is actually needed to be able to do such a useful things with Python. I really need to learn this thing :-)
