Hi Alex,
Well done for getting so far, documentation is still lacking so it shows some perseverance on your part.
Interesting hack you are trying, without investigating why your icon doesn’t make it into the final image I would guess that the yarn install command which is run as part of ./gradlew clean installDist causes your modifications to the @mdi package in node_modules to be lost.
You can always do what your doing (placing the svg into the @mdi package and then generate the mdi-icons.json file using:
cd ui/component/core
npm run generate
The mdi-icon.json file will be in the dist folder, you can then copy this into a running manager container or use a volume mapping, the path within the manager container is:
/opt/web/shared/mdi-icons.json
The more structural approach is to use a custom icon set as demoed/tested in code at:
Inspired by what the old polymer iron icons used to do, you can essentially have sets of icons and mdi is set as the default in our UI components we also have an or icon set which just has OpenRemote logos in at the moment. To use an icon set you just prefix the icon name with the icon set name e.g.:
or:logo
Using this mechanism you could load your own iconset but you’d need to write some UI code to do this so your hack is the quickest approach.
