Bug fix: the fields that are not supported by vendor should be "N/A" …
Browse files Browse the repository at this point in the history 
…in STATE_DB (#168)

- Initialize fields as "N/A" and set the field to "N/A" for those not supported by vendor API
- Update set_voltage, set_temperature, treating "N/A" instead of None as invalid values
- Update unit test cases accordingly
