Support custom icons in standalone mode

[HenkRenting]

Describe the bug

I use 2 Zigbee adapters in 2 separate Z2M Docker containers. And load those together in a 3rd container with Windfront.
In that 3rd container (custom) device icons are not inherited from the actual Z2M instance.

To Reproduce

Change device icon in original Z2M instance

Expected behavior

Same device icons in both interfaces

Affected browsers

Chrome

Stacktrace

This is not supported at this time, since the Z2M instance and the WindFront instance are separate in this configuration (only the Z2M instance knows and serves custom icons).

[HenkRenting]

Ah, I see. Thanks for the quick response.
Would be nice if you could enter a url to an image outside the docker container.
That way you could only copy-paste the url. Or even let it inherit if from the other Z2M?

[Nerivec]

You can actually use a full URL, but you have to do that from Z2M side, in device options.

It should also be possible to integrate custom local icons in the WindFront instance by mounting /usr/share/nginx/html/. The frontend should just be requesting images from device_icons/{xyz}.png if memory serves, so, as long as the files are there, it should just work.

I haven't done any testing on this yet though. If you do, be sure to let me know what you find out 😉
