Problem description

Circulating Pump integration seems to have issues:

• You can't controll the pump at all
• The sensor showing the state doesn't have a unique ID
  Diese Entität ('calendar.circulating_water_in_xxxxx_domestic_hot_water_0') hat keine eindeutige ID, daher können ihre Einstellungen nicht über die Benutzeroberfläche verwaltet werden. Weitere Informationen findest du in der [Dokumentation](https://www.home-assistant.io/faq/unique_id).
