Get Netatmo Readings.
Epochs are Unix Timestamps for each Modue in Seconds.
Readings are Netatmo readings with the following units.
- Noise (dB)
- Temperature (C)
- Humidity (%)
- Pressure (Pa)
- CO2 (PPM)
For example, readings for the defaults args would look likes this:
> readings = {'Living Room': {u'Pressure': 1011.7, u'Noise': 37, \
u'Temperature': 20.7, u'CO2': 594, \
u'Humidity': 40}, \
'Bedroom': {u'Temperature': 18.6, u'Humidity': 38}}
Epochs would look like:
> epochs = {'Living Room': 1461231951, 'Bedroom': 1461231922}
@param: station - Netatmo station to poll [String]
@param: modules - Netatmo modules to poll [List of Strings]
@return: readings - Netatmo Readings [Dict of Dicts]
@return: epochs - Timestamps of Readings (Seconds) [Dict]
