Supporting multiple devices

[adiutores]

This script is built for a single device—global IP address, credentials.json file, etc. My use case is for multiple devices.

Would it be helpful if I extended for this?

I don't think it's necessary.

As mentioned in #13 (comment), for HASS integrations there should be one project responsible for the HASS logic (sensors, media players, services, etc.) and one for the device logic as a dependency of the former.
The handling of multiple devices could be handled by the HASS side (e.g. by passing distinct credentials.json paths to the lower level project).

If you're implementing Wake on LAN in the device-related project however, you may want to save IP-MAC pairs if getting them using ARP/RARP/DHCP is not possible. And when you're at the point where you save IPs and MACs anyway, you may as well save them together with credentials for that device.
