Web-Interface to interact with my HVC

Of course you need to run a web server on your RaspberryPi, to enable this feature.

The interaction between php and pyton in handled via files. On the one hand the log files of the control are read and the current values shown. On the other hand, configuration data is written to interact with the control.

In the first line a session has to be started to use cookies for loggin in.


main

The main function has two purposes:

  1. Pagelayout
    With the strings $head and $foot the layout for all pages is centrally defined.
  2. Pagecontent
    What is shown is controlled via $what2do which indicates which functions should be executed by the switch-case structure.
    If $what2do is not set, the default page with the overview sketch of the house is shown.
    In any other case it is checked first whether the user authentificated herself such that $_SESSION['IamGod'] is set - if not the user is redirected to the login.


HV_Admin_Login

Function to login/logoff the user.
Special feature is the increasing delay if someone should try to steal the password.


HV_showHouse

Composes a SVG graphic with the sketch of a house and alle sensor values and actuator states are visualized.


HV_showWeatherForecast

Just to indicate that the pulling of the weather forecast works, this fuctions reads the last line of the weather logfile and shows its values, plus an outlook of the next 48 h as graphic.
