Inspecting discovered components

I am wondering if there is a simple way of inspecting discovered components configuration so the information can be used to hard code the component (and then ignore it). I am running Hass.io in a Docker if that matters.

How does Hass.io identify components uniquely? By the IP address? What if this changes; does it think it is a different component?

automatically discovered devices should show up in known_devices.yaml in the root of the config directory.

You can see a list of all devices in the /dev-state page and you can edit them via customize in your configuration. It all depends on how the devices are discovered and what you want them to do.

Thanks for that.
[edit]Realised I needed the device tracker component to see that file but I do not have a compatible device for the component.
