How does Homey process power measurements via setCapabilityValue?

I was not aware of the concept of sub capability. I tried to look up some documentation on that, but I can only find it briefly mentioned in Using the same capability more than once.

Will Homey treat the meter_power.daily different than meter_power, or is it just that the associated title will give the sub capability meaning because it carries e.g. the “daily” description?
