I just found this project from Microsoft on GitHub and I’am curious if it would be possible to use that as a web based rule/item etc. editor for OpenHab.
On the GitHub page the question if extensions would work is anwered with “no”, but there is also a note that it might be possible:
I don’t know exactly how the OpenHab vscode extension is built. Could this maybe work as a new UI in a future version of OpenHab to edit all files directly in the browser?
