Add Logo (Image) for Ping-Only Device

FYI, I have this working - sharing in case others want to try this as well. What I needed to do was,

  1. Save a (optimized) image, at html/images/os/roku.svg
  2. Create a definition file (includes/definitions/roku.yaml), contents as below,
    os: roku
    text: ‘Roku’
    type: network
    icon: roku
  3. Force the os to “roku” for the desired devices. I had to do this through MySQL, it didn’t seem to work through the web interface (should it?).

Then it works! And both discovery and polling don’t really run for this (ping-only) device, so the yaml file is just fine.

Thanks for the pointers!
