This module implements a graphical user interface for the thermostat module.
The user interface is provided on a small TFT display which is supported by the fbtft kernel driver. It is implemented as a web page which is diplayed by a local web browser (Midori) in full screen mode. The communication with the thermostat module which provides the data to be displayed is handled by a seperate PHP file, accessed from the web page through the local web server (lighttpd).
Alternatively to the local web browser, the user interface can also be displayed on any external web browser, e.g. on a separate Smartbox or a PC or Smartphone, as long as these have access to the thermostats web server.
See the following picture for an architectural overview.
The user interface provides the possibility to display the current room temperature as well as the outside temperature and the weather conditions. The latter are retrieved from the Internet and don't need a local sensor. The interface also displays the selected target temperature and allows to modify it via "up" and "down" buttons.
The parameters needed by the Thermostat GUI are read from the global Telegea config file.
