The knXpresso HTTP request plug-in is a functional extension of the knXpresso app.
The http request plug-in establishes the connection to the KNX bus. This allows HTTP requests to be integrated into your KNX system.
The knXpresso HTTP Request Plug-in enables receiving HTTP commands.
Many applications, such as Web browsers, the APPs Tasker, IFTTT and many more can send HTTP request commands. Actions on the bus (switching, entering values, etc.) can then be carried out via such received http commands.
