eHouse Smart Home visualization – Java

Visualization of eHouse smart home system in Java

eHouse Smart home system graphical visualization, extends eHouse development libraries for the intelligent home system and makes possibility of independent creation of software by end users of the eHouse system, associated companies and companies wishing to individually develop eHouse system for Java SE .

eHouse for Java (eHouse4Java) are Android and Windows Mobile compatible libraries allowing you to create your own software for control panels and PADs.
Library is an application template which can:

  • load on the system configuration, the names of the controllers, outputs, inputs, sensors , etc.
  • providing communication with home automation controllers
  • reception and decoding of controller status data
  • send control commands graphically ( with visualization objects ) or textually ( the fields selected )
  • control system via WiFi , Internet , SMS , eMail
  • graphic visualization and control – load a text configuration file of graphic objects associated with the events to be executed ( control commands ) and device statuses
  • automatic visualizations for RoomManager or other controller

Visualization is created using Java swing library like: JPanel, jbutton, etc. .
These objects are automatically “double-buffered” , thus eliminated the flicker effect , very annoying for the user .

The user has the ability to control the image:

  • Zoom in and out
  • moving up , down, left, right
  • change the current view by choosing “Options”
  • return to the graphical visualization of the system by selecting “View”

Visualization Example of eHouse system:

Zoom in and out ( zoom in and out ) implemented using scalable vector graphics ( SVG ) , so that the image does not lose quality when you change the scale:

Configured controllers are automatically displayed :

Statuses is updated through the network or the Internet (TCP or UDP) – online (real-time)

by selecting the ” Options ” and the room can watch the states drivers and select programs . Changing the status of incoming UDP will automatically rewizualizację :

In addition to visualization of the individually designed based on the architectural design and installation of smart home there is also automatic visualization created independently for each controller in the system (in particular for RoomManagers and EthernetRoomManagers – for individual rooms ). This allows for independent control panels and visualize for each room individually , without tedious creating visualizations based on installation design.
