* Inconsistent entity_id when multiple sensors
I am submitting a change to fix a [bug](https://github.com/home-assistant/home-assistant/issues/16204) for when there are several sensors for the same hostname. For example I want to track my IPv4 and IPv6 address. It creates two entities that regularly switch ids based on the order they get initialized.
To fix this I comform to the way other componnents have addressed the issue by adding an optional `name` attribute.
