I want to make a user-friendly list of devices that are offline so that a householder who is not particularly technically minded can find them and check that they are plugged in and connected to WiFi or ZigBee as applicable.
I found several postings on this forum and elsewhere, mostly focused on entities that are unavailable. That is not what I want because
a) Each device typically has several entities and I don’t want the duplicates
b) Sometimes some entities are unavailable for a device that is actually working, probably due to an obscure device configuration (quirk) error.
c) Entities can include items like automations that are not devices at all. I only want the real devices (what the householder can see).
I don’t really know what I am doing (!) but by experimentation and borrowing from all over (thanks) I have cobbled together a sensor that delivers in attributes (because the state cannot exceed 255 characters) a list of entity ids, a list of entity friendly names and a list of devices by user-defined device name.
All three work to the extent that they produce a list using the correct name. However, if I then look at the listed devices or entities in the UI, I find that they are not all unavailable. Apparently the filtering is not yet correct.

# these results have to be attributes because the state cannot contain more than 255 characters

I would like to know
- How to distinguish the main entity for a device (the device itself)?
- How to list all the DEVICES on the system?
- How to filter on unavailability of the device itself, not just some of its entities?
- What exactly the ‘map’ function does?
