ZHA Power/Battery Status UI Update

Hi, just a small and probably simple feature request for the ZHA integration.

Background:
When opening the list of ZHA devices, you can currently see the column “Battery” and it shows “-” for powered devices, offline devices and a battery percentage with battery icon for battery powered devices. It is not easy to determine from this list if a device is powered or unavailable/offline.

Proposed Feature:
Update the “Battery” column to be “Power” or “Power Status” and for currently available devices that are non-battery and are powered, show a power plug icon, with or without the “-” currently shown for powered devices. Battery powered devices that are online could be displayed the same as currently (percent and Icon). Unavailable devices could then be shown with only a “-” or even some Icon indicating it is Unavailable.

This would make determining if any ZHA devices are offline easy with a glance at this page. I currently setup lovelace views and automations with notifications to stay on top of offline devices but this would make it very easy and user frindly for all and save those extra steps.

Cheers

Michael
