Maximum requirements for eHouse visualization from an Internet browser are JavaScript and SVG (Scaled Vector Graphics) support.
Working examples of the included eHouse 1 test system under the supervision of RaspberryPI, various methods of visualization and graphic control online can be found at: Intelligent building visualization .
We provide JavaScript source codes for visualization and graphic control enabling:
  • open source JavaScript code allows you to modify it for your own and individual needs for each project
  • sending events
  • drawing graphical objects in a similar way to other visualization methods in eHouse software
  • script work on the side of the browser / client that does not additionally load the server for status processing for each client
  • status data update
  • Script work is optimized for the minimum data processing, which is especially important for battery devices, tablets, smartphones
  • change of dynamic fields - text on values ​​measured and calculated dynamically by the script
  • supports the status of eHouse1 controllers, eHouse1 under the supervision of CommManager, Ethernet eHouse
  • drawing / hiding objects on and off

Basic ways of graphic control and visualization:

JavaScript Scripts:
An intelligent building - JavaScript graphic control - Source code and
Smart Home - graphic control and JavaScript visualization - Source code

Visualization was created in the CorelDraw X4 application, its sources can be found in the following files:
eHouse Home Automation - Visualization of CorelDraw and
eHouse Home Automation - Visualization of CorelDraw - Attic .

All types of the above visualizations have been created from a single image.
The macros for creating visualizations allow generating output files for a specific panel size (given in centimeters for the X and Y axes), thanks to which you can generate different visualizations for smartphones from one image, tablets, PCs (touch screens), panels.
Because the visualization and graphic control is made using SVG (scaled vector graphics) images can be reduced and enlarged without losing quality.
