Special Electronic Design

The electrical system globally exploits the use of contactors in bistable relay for the control of devices that are not natively provided for a home automation system. The home automation control adapters have been added at a later stage and positioned in parallel to a pre-existing plant, in order to read the status of the devices and control the contactors. In this perspective, it wanted to show that it is possible to ‘extend’ a classic system with home automation controls, also to limit the planned set of activities and allow for retrofitting low costs. The Easybox cards are therefore used to add a classic on the system advanced features, including:

  1. Timing the ignition of the fan coil, in order to ensure the homogeneous air conditioning of the rooms.
  2. Timing the turning off of devices, in order to minimise the wastage from forgetfulness.
  3. Collect data on the use of the devices, in order to estimate the fuel consumption and the resulting savings, compared to the scenario of a classic system.


The system is run on a workstation WIN 7 Intel Core i3 and 4GB RAM; The same machine also houses a SQLSERVER 2008 server.
