What's Changed
- Some weather entities don't have an attribution attribute, so don't require it. If it's not present and the entity's state is not a number (or if the entity hasn't been fully initialized by the time HA completes initialization), just default to using the standard condition-to-divisor mapping.
- When the above happens, write an appropriate message to the system log, but make it a DEBUG message to avoid annoying WARNING or ERROR messages when using a weather entity that does not have an attribution attribute.
