PyCalima

Simple python interface against the Pax Calima® <http://www.pax.se/sv/produkt/calima/pax-calima-flakt>_ bathroom fan created and sold by Pax® <http://www.pax.se>_

This module provides a very simple interface against the various GATT characteristics of the Calima fan, most importantly it handles the authentication so values are actually persisted within the fan.

Command line tool

Pretty useful command line tool which among other things can print all the characteristics of a fan. It can also search for available fans if you don't know the MAC address.

For more on using the tool, just run calima -h.

Debugging

Set this to True in pycalima/Calima.py file if want to see more verbose output.
