I think this is because None is not a valid device_class. We probably should just not assign it in that case.

I expected that None is valid entry for generic sensor. We can leave it empty. Question is if dev_cla is optional or mandatory.

device_class is optional (https://www.home-assistant.io/integrations/sensor.mqtt/). It automatically sets thing like icon in the card. I can see it also being used to present value differently
