Should fix the following sentry error:

java.lang.IllegalArgumentException: stepValue=0,000000 <= 0

According to the input_number code we don't need to adjust much as they already take care of most requirements:

It seems the issue here is that when an entity was restored to unavailable all attributes come in as null since they do not exist and that is why the defaults matter for input number as we set them based on current attributes
