Issues with "off" sensors and invalid numeric values

[paoloantinori]

Describe the bug
Multiple instances of this message in the logs:

ValueError: Sensor sensor.frigorifero_fridge_temp has device class 'temperature', state class 'measurement' unit '°C' and suggested precision 'None' thus indicating it has a numeric value; however, it has the non-numeric value: '-' (<enum 'StateOptions'>)

Expected behavior
Either not ending up in such an inconsistent state or adding some defensive logic to support and discard these values.

Additional context
The issue normally goes away if I force a reload of the integration from HA.
I've noticed from the screenshot that the appliance reports as being off despite I can confirm that from an hw point it is on and connected to wifi.
