I did not need this before, because once we need to access the UI from remote, we already put an NGINX proxy in front (see this German post for a working NGINX config: [UI am Raspberry konfigurieren - #2 by stefan.feilmeier](https://community.openems.io/t/ui-am-raspberry-konfigurieren/72/2))

According to…

> <https://stackoverflow.com/questions/67134737/host-an-angular-project-on-localhost-and-allow-access-from-a-different-network/71528882#71528882>

…it might actually be sufficient to run UI via:

```auto
ng serve -c openems-edge-dev --host 0.0.0.0

```

Official docs is not very clear on that, unfortunately: [Angular](https://angular.io/cli/serve)
