Remaining time?

I think this would be useful. The idea is to calculate how long the battery will last at the current power usage level. I’ve seen a few people make custom sensors to do this but it would be great if it could be part of the integration. Would be very useful during a grid outage!

I have a few ups power supplies that do this and I find it much more useful than the battery percentage alone.

I like this idea, although I think this calculation should really stay separate from the card itself.
You could probably use a template sensor for this.
What I can do is expose the secondary_info object for the battery (like it is available for other circles)

Your right that makes much more sense to have the display ability and feed in a sensor for the time value.
