Without the examples I can only show you how to list all HA devices:

from homeassistant.helpers import device_registry
from homeassistant.helpers.device_registry import DeviceEntry
from typing import List

registry = device_registry.async_get(hass)
devices: List[DeviceEntry] = registry.devices.values()

The devices object is filled like so: https://github.com/home-assistant/core/blob/2024.6.4/homeassistant/helpers/device_registry.py#L977
The DeviceEntry object is described here: https://github.com/home-assistant/core/blob/2024.6.4/homeassistant/helpers/device_registry.py#L977
