Integration of own data to display

[lobin]

Having a Wall Display, I'm looking for a possibility to use it as a commando center to controll my home automation consisting of many devices and controlled by openhab. However, I was not able to find any possibility to display own data (provided by json feed for example).

Is there any possibility to customize it ?

yes this would be of great interest, I'm for example looking for a way to display the current electricity-price on the display

A simple command to show a bitmap on the WD (fullscreen) would be great. A HTTP request of an action could return a PNG file (e.g. base64 encoded).

Or a bitmap could  be pushed via REST API.

And if the WD would report the coordinates of finger taps and gestures, a local server (e.g. Raspberry Pi) could use the WD as an external display.

Very simple and extremely flexible. Would love such a feature!
