~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Shows sensor values from tellstick sensors.
Possible config keys:
id of the sensor: Name the sensor with ID
135=Outside
only_named: Only show the named sensors
only_named=1
temperature_scale: The scale of the temperature value
temperature_scale=°C
datatype_mask: mask to determine which sensor values to show based on
https://tellcore-py.readthedocs.org
/en/v1.0.4/constants.html#module-tellcore.constants
datatype_mask=1 # only show temperature
datatype_mask=12 # only show rain rate and rain total
