INTRODUCTION
SIMPLEHOME: DISTRIBUTED INTELLIGENCE AND PROPRIETARY PROTOCOL
Creating a distributed intelligence home automation system guarantees the following:
- limited system costs, even for small installations such as single/two-family apartments, because - as with centralised logic
systems - it is not necessary to install a control panel;
- greater protection against potential system locking, due to the fact that if a module is locked (e.g. following a surge or flooding),
only the services (loads or commands) served by that module will cease responding to commands, meaning that the rest of the
system can continue to run as normal;
- use of normal cables (even electrical cord, where permitted by law), limiting costs and material management: SimpleHome
actually uses three normal electrical wires sized in accordance with the length of the bus and the number of devices on the
section. It should be noted, however, that shielding offers greater protection from disturbances caused by magnetic fields.
SIMPLEHOME: MULTIFUNCTIONAL MODULES, DISTRIBUTED POWER SUPPLY
The Comelit home automation system does not require modules dedicated to specific functions, such as rolling shutters or
scenarios, as each bus device is multifunctional and can be programmed to carry out any task.
Moreover, some of the SimpleHome modules offer the option of on-board power outputs with the same number of digital inputs
available, optimising system configuration and significantly reducing the total cost.
The system power supply is provided by 24 Vdc 2A DIN bar power supply units, which can be fitted in parallel and therefore
distributed freely along the entire bus, meaning the bus sections can be significantly reduced (if the electric loads are suitably
balanced) and guaranteeing (where necessary) a backup system which is easy to create.
COMMUNICATION TYPE
All devices communicate directly between themselves without a supervision/control panel, and therefore the communication time
dos not vary as the system expands: it takes the same amount of time for two modules speak to each other whether the system
consists of 2 or 200 modules.

Modules with inputs, when the status of one of these changes, send a single message which can be destined for:
- another module, to activate an output;
- a group, i.e. to an assembly of common outputs needing to be controlled simultaneously;
- to the system manager, if complex scenarios are required.
To clarify the concept of the Group , let us consider the following example: all outputs (distributed across several modules) controlling
the lights on a floor or in a building belong to the same zone, and these can be controlled individually; alternatively, to switch them
all off at once, simply use a single button connected to an input module which will send an off message to Group 1 and therefore
to all users belonging to it.
This document presents a short introduction to the philosophy behind the Comelit home automation system and provides a detailed
description of the range of home automation products currently available.
