this battery provider implementation subscribes to a user-configurable MQTT topic to retrieve the battery SoC value. the value is not re-published under a different topic. there is no card created in the web app's live view, since the SoC is already part of the totals at the top of the live view. that is the only info this battery provider implements. closes #293. relates to #581.
