Proposed change

Add serial_number to device registry entries

The serial number can be displayed in the device card in frontend

The "identifiers" set which is part of device registry entries can't be used for this purpose because:

  • they are globally unique
  • we have no idea what they are, it could be a serial number, but it could also be anything else used by the backing integration

Developer documentation: home-assistant/developers.home-assistant#1477

Note: This is a rebased version of #77713

#77713 was reverted by #79139 because there was an idea that we would like to add additional attributes and collect them in some sub data structure with device meta data.
However, the specific case with serial numbers was brought up again in home-assistant/architecture#987, and there's no consensus on any additional attributes.

After a discussion with @edenhaus, @MartinHjelmare and @frenck, we concluded serial number is wanted and we should add it without any bigger architecture change to the device registry.

The serial number can be displayed in the device card in frontend

Users have trouble identifying which device is which when integration don't provide a name (because they do not have a useful one in the data source), and only a mac address or serial number. This will be very helpful in figuring out which device is which if we also include the mac in the UI

entry = registry.async_get_or_create(
config_entry_id=mock_config_entry.entry_id,
connections={("Zigbee", "01.23.45.67.89")},
identifiers={("serial", "12:34:56:AB:CD:EF")},

It would be nice if the serial didn't look like a mac address in the test as it initially confused me

The code LGTM, but I don't follow why the first version was reverted in #79139. I am missing some context

Does this need a frontend PR before merge or are we good to merge?

LGTM.

I think we can merge this without having a frontend part at this point.
Will make a task for the frontend team to pick up.
