Dear Andrew,

I'm using your integration for all my battery devices since a while. Unfortunately there is no good dashboard card to show all my devices in a table.

Describe the solution you'd like

Therefore I have created a dashboard card as a pendant to your integration. Please check it out.

Hi, that looks very neat and certainly gives people a good option for dashboard usage.
I've added it to the community page so people can find it.

Thanks for taking the time to create it.
