Edward Firmo 14532444bc Fix for "Error rendering data template" ...

This fix the following error which happens when an entity with a non-numeric value ('unknown', 'unavailable', some text, etc.) is sent to the device:

```
Error: Error rendering data template: ValueError: Template error: round got invalid input 'Geen' when rendering template '{{ states(repeat.item.entity) |round(1) }}{{ state_attr(repeat.item.entity, "unit_of_measurement") }}' but no default was specified
```
This may also implement the feature requested in #490
