Perhaps this is a bug, if so, I've searched and not found anything.
The "Entities" (note the plural) card is ignoring the units set in the entity it's displaying.
I have the Ping integration tracking, well...ping times. The "Entity" (singular) card shows ping times in ms, as expected. The "Entities" (plural) card shows them as seconds, regardless of the unit I set on the entity itself. Is this intended behavior?
