This module reads from the Landys & Gyr Ultraheat heat meter unit and returns the meter values. Note: An (USB) IR reader is needed and connected to the machine running the python script
WARNING: everytime this is called, battery time of the Ultraheat will go down by about 30 minutes! This package has been tested with the Landys & Gyr Ultraheat type UH50 (LUGCUH50). Other models are likely to work as well.
