1. INTRODUCTION
ChoruSmart allows you to create traditional, Connected Smart Home or Home&Building Pro systems in a
complete and scalable manner using the best available technologies, completing them with the wide range of
formats, colours and finishes of the devices and plates offered by GEWISS.
Traditional system
The ChoruSmart offering for traditional systems is
composed of wired technological and aesthetic solutions,
both simple and advanced, for any building type. It offers
innovative control points such as the EVO axial versions
and touch versions, allowing you
to centralise lights and
roller shutters with ease, as well as traditional tilting and
soft click commands. The range also includes Italian and
international socket-outlets, technical alarms, signal take-
off, protection, personal security and domestic comfort
management devices.
Connected Smart Home
ChoruSmart also allows for a variety of connected devices,
giving rise to a range of intelligent, convenient and
wireless solutions. EGO SMART
plates, the distinctive
elements of the entire ecosystem, offer
a unique and
customisable interface with which to control domestic
consumption, security and comfort with ease and
simplicity.
The Zigbee
wireless protocol allows for integration with
the most important smart speakers on the market with
Google Home, Amazon
Alexa and IFTTT IoT platforms,
thanks to the Home Gateway App, allowing you to manage
lights, roller shutters and scenes by voice, as well as
checking on your consumption or receiving notifications of
issues. The wireless controls, which do not require
batteries, also allow you to add other control points at any
time with complete freedom.
The ChoruSmart Connected Smart Home
offering is the
perfect solution for residential and small businesses, both
for new buildings and for the renovation and revamping of
existing systems with minimal structural interventions.
Home & Building Pro
If the ChoruSmart range is completed with BUS wiring
using the international standard protocol KNX, it is
possible to create an advanced, expanded system. You will
have an intelligent and customisable system at your
disposal, complete with all functions, w
hich is able to
integrate with third-party systems and devices – video
entryphones, smart locks, entertainment – controllable via
apps, voice assistants or touchscreen panels. The Home &
Building Pro system is suitable for advanced automation of
residential solutions and small or medium-
sized business,
and guarantees security, well-
being, efficiency and
sustainability.
This system manual describes the Connected Smart Home solution.

be configured via the app, and some functions will be lost (for details, consult the
installation manual).
Functions:
•Two operation types: heating and cooling
•Three operating modes: OFF (anti-freeze / high temperature protection), heating,
cooling
•Regulation of the operating setpoint
•Automatic temperature adjustment management* (AUTO mode), activation of
weekly temperature control profiles managed via App (cloud)

way systems: Two points (ON/OFF command), PI
proportional (PWM type control)*
•One relay output with NO/NC change-over contacts
•One input for external NTC temperature sensor**
•Zigbee window contact management*
•Humidity threshold management*
•Dew point*
•Display of the unit of temperature measurement in °C or °F
* functions available only in connected mode, paired with the GW1x840 - Home Gateway.
** both functions are available only in connected mode, paired with GW1x840; in non-
connected mode (conventional systems), only compensation of the temperature
measured locally is available.

3. SYSTEM SPECIFICATIONS AND ARCHITECTURE
The ChoruSmart system uses wireless connections based on the Zigbee standard protocol. Installing the Home
Gateway allows the ChoruSmart system to communicate with the house WiFi network. The home router allows
the system to communicate with the cloud, and as a consequence, with the Home Gateway App, giving the user
access to all the smart functions offered by the ChoruSmart system (scenes, monitoring of consumption, loads
management, cloud/IoT integrations, voice commands integration, use of IFTTT applet).
NOTE: the Home Gateway - GW1x840 uses the 2.4 GHz WiFi band. As such, it cannot use 5 GHz WiFi networks.
BASE FUNCTIONS
SMART FUNCTIONS
The base functions of the traditional system, lights,
roller shutters, controlled sockets and temperature
regulation, can be implemented in wired mode
(recommended) so that they function immediately
after installation, before performing the system
configuration.
The smart functions are obtained via wireless
connections via the connected devices: scenes,
consumption management, app-based supervision and
control, voice commands, cloud/IoT integrations.
