Allow aliases for devices

Hi there, great project. Been having fun setting it up.

I have a feature request to make: allow setting up aliases for devices. Here's how my dashboard looks:

These devices are being reported from my router by a script I made. Now, I could have used the hostname but I don't want to take the chance that one of the devices changes name in the future, so I went with MAC address.

Having said that, it's very difficult to determine which device is which at a glance. I'd love to be able to send the hostname as an alias so it could be easily identified in the UI (which I use for manual learning).
