I wrote a small Lua application which parses the user_data and creates a compact HTML GUI for Vera. This is just a proof of concept, far from being a complete implementation, and requires firmware 1.0.862 (may work with 1.0.843). Source code attached.
@MiCasaVerde:
I am going to implement this GUI creator as a Luup device. The user should be able to
recreate the HTML GUI code by pressing the “Configure node right node” button - but
as far as I know such a button (and a corresponding hook) is not available for Luup
devices (at least in the current Luup release).
