Hi,
I made a custom dashboard for openhab using the REST API. Not sure if this is the right place for this, please move it if not.
It is based on a fixed grid system and optimized to fill the entire screen. Here are some screenshots:
Pressing a Dimmer Item opens up a slider:
Pressing a Switch toggles the item.
The whole dashboard is configured using a single JSON file. You set the location of that file as well as the API base URL on the /config page. More details for setup on github.
So if anyone else wants to use it or even contribute, here is the repository:
Update: Version 2.0.0 is out with a new theming engine that relies on pure CSS. It allows for finer theming. You can use classes for background, boxes and active boxes. The pages have a data attribute with the page name so you can make custom themes for every page and even every item.
