Smart Home HI-TECH BUILDING 2015


Type of building Residential Building - Other
Number of KNX devices 16
Summary Since 2013 IBC Solutions has annually taken part in “HI-TECH BUILDING” - the largest and most popular building automation tradeshow in Russia. In cooperation with the organizers of the trade show, we decided to create the first “Smart Home” project to develop this trend in our country. When we conceived the project, it was already clear that we would use KNX. In the 2014 Smart Home project, there were several system integrators, all of which tried to demonstrate their own building automation technologies and solutions. Once again, our KNX product choices allowed us to present an attractive and powerful solution, with various control possibilities. This year’s installation increased to a “Smart City” scale. The Smart Home project was a part of the Smart City, consisting of three zones – Kitchen, Bedroom and Living room. We relied on our previous experience and offered a completely new way to look at a Smart Home system.
Main technical highlights The KNX alarm system allows you to observe the state (battery level to the state of control of various types of sensors) and to manage (whole house arming, or certain areas). The KNX audio multi-room system can control numerous audio parameters. It is possible to setup input gains on each audio source, initial volume levels, equalization, and output limiting for each audio zone. A customizable user interface with complete system control. Multi-touch switches, a smart thermostat, an iPad and touch panel that allow system control, replacing ugly security keypads or thermostats.
Benefits of KNX Using KNX equipment from one of the top manufacturers, we created a Smart Bedroom with incredible functionality and control capabilities. A KNX alarm system with a biometric system made our Smart Bedroom an example of a truly secure Smart Home system. Multi-touch switches and a smart thermostat from the company Basalte, created an atmosphere of stylish ergonomics with diverse control. The KNX multi-room audio system Asano and a Mirage Media Server provided the bedroom and bathroom areas with high quality sound. All combined subsytems functioned flawlessly as a homogenous system.
Which functions were realised with KNX We used JUNG dimmers and actuators to manage lighting, blinds, circulation water pump. JUNG Push button interface for leakage detection. EVIKA LED driver for RGB strips. Zennio KES energy meter. Basalte Sentido and Deseo switches and smart thermostat to control lighting, blinds, audio and arming the security system. Basalte Asano P4 multi-room system for sound distribution and playing alarm messages. Satel KNX module for connection with the alarm system. For gateways, we used CI-KNX for Crestron, Wienzeirl Baos 772 for KNX-IP integration and Basalte for Mirage Media Server control.
Lighting Bedroom lighting included a chandelier, bedside lamps, and LED RGB illumination of the dresser. Bathroom lighting included the main fixture, mirror lights and LED RGB lights of the locker. All lighting groups included individual scenes. Common scenarios for the two zones were programmed, “Security On”, “All Off” and scenes. The unique properties of multi-touch keypads allowed bedside two-way switches to dim the bedside lamp and the chandelier, control blinds and activating four different scenarios with a long-term multi-touch press. Each scene was indicated by a unique LED backlight color.
Shutter control In the bedroom, one group of blinds, as well as the lighting groups, were controlled individually and by scenarios. When leaving the house, the user had to press and hold the main switch with the palm of the hand and wait for the purple scene “Security On”. The light turned off after a short delay, the blinds closed, and the security system armed. Upon entering the house, it was necessary to put a finger to the fingerprint scanner and, depending on the user, the system activated the appropriate lighting groups, blinds opened or stayed closed.
Heating, ventilation, air conditioning To demonstrate of the climate control system, we used a red LED strip, which was located behind a wall-mounted radiator, and a blue LED strip on the air conditioner louver. Air conditioning was controlled by an IR signal sent by the Crestron MC3 processor. When the room controller Basalte Deseo sent the status - mode "heating", the red lights behind the radiator were On, and the air conditioner with it's blue light were Off. If the air temperature and the set point were equal, red and blue lighting were Off. This demonstration was visually intuitive.
Alarm Systems The Satel alarm system became the highlight of our project. Using a biometric fingerprint reader, multi-touch switches, as well as a touchpanel, we armed and disarmed the system and displayed its basic settings. The motion sensor watched for room intrusion. The built-in LED light was blinking, indicating the countdown before arming. At the same time, the multi-room audio system played the voice message "Goodbye owner, the system is armed". The biometric system allowed us to greet the owners personally with the messages such as: "Welcome Igor, the system is disarmed" as the light turned on.
Smart Metering On the main control panel, the current and accumulative consumption parameters were measured by the KNX electricity meter were displayed. Visitors could observe these parameters changing depending on the status of lighting and other systems, by periods of time - per hour, per day. Further to the average volumes, the total peak was also displayed.
Audio / Video The multi-room audio system was made completely on KNX equipment, without third-party processors or software gateways. The bedroom room controller allowed playing Internet radio stations, playlists stored on the server, or TV audio. In addition to volume level and track listings, the display showed Metadata about the current track. Activation of different scenarios allowed playing pre-configured radio stations or playlists in one or more areas of various volume levels. Alarm events switched the multi-room amplifier to priority source, which streamed audio from the alarm voice messages module.
Visualization The 15” touchpanel included an Iridium mobile software interface. The main page showed weather, news feeds, status of power system leak protection, surveillance cameras and security status. The panel also controlled lighting, climate, blinds and audio system in both zones. All this functionality was also available on the Crestron iPad interface, as well as video management with the ability to select and play movies, and control the TV. Also on the iPad, when you receive a call from the SIP video door entry system, a screen appeared with a response popup for receiving a call.
Interfaces with other systems The project used a Crestron control system for several purposes. The MC3 Processor controlled air conditioning through IR commands, a Panasonic TV using RS-232, UDP control of an HDMI network media player using XBMC, as well as gesture control, using a Myo armband. Using a KNX-IP gateway, we implemented two-way communication with the KNX system, allowing one hand to manage the lighting, curtains, climate and other Smart Home functions with a wall-mounted iPad, and the other hand to control the video system, activating various scenarios.
Other applications A completely new solution for our visitors, and for ourselves, was the lighting system control utilizing gestures. It was enough to make a fist in order to turn on the chandelier, or to open your fist to turn off the chandelier. To create such a solution, we used the Myo Bluetooth armband, which recognizes five hand gestures. It was developed in Visual Basic to receive commands from the armband and translate them into the UDP format. Next, the Crestron processor took these commands to controls lighting, passing KNX commands to the dimmer to control the chandelier.
