This service update fixes warnings that occur in the log of Home Assistant core when not all attributes are published during sun down.
The total_energy and today_energy attributes will be cashed an published even when the sun is down. The other properties are not updated during night and do no longer share a state topic.
If you are a MQTT user, but are not using Home Assistant auto discovery, keep in mind the state topics changes for all published attributes.
Home Assistant users should not notice any difference.
The omnik attributes that are not always available have been moved to a new asset class `omnik_attributes`. This is changed in `data_fields.json`.
If you have customized this file, you might need to update it with the new base.
