Your sensor sensor.unavailable_entities returned an empty string ('') instead of a number. As it has a unit_of_measurement it is required to be a number.

If you are returning a list of entities, remove the unit of measurement from the configuration.

If you are returning a count of entities, something is wrong with your template.

Thank you.
