Device Class for volume/capacity states (i.e. robot vac trash bins)

[woodford86]

I really like the binary sensor device classes, but one that is missing would be a Full/Not Full class. This would be useful for things like robot vacuum bins, smart cat litterboxes, could also be used if someone has set up sensors for garbage bins, laundry baskets, anything volume oriented like that.

Hoping other people agree!

I think there is another thread asking for this.

Fundamental problem: is the vessel half full or half empty?

Device Class indicating Full or Empty

A Binary Sensor device class that indicated Full or Empty would be great. It could be great for many things with a float switch Such as a rain barrel, overflow tank, Aquarium, a fuel tank, water tank. Overall I think it wold be useful for many things.
