Energy harvesting wireless solutions from different member companies forming a network of intelligent HVAC and lighting control combined with security and energy management
San Ramon, CA/Amsterdam, Netherlands, 19-9-2014 — /EuropaWire/ — Interoperability of several devices and solutions is key to smart homes. At European Utility Week 2014 (RAI Convention Centre, Amsterdam, 4-6 November), the EnOcean Alliance will demonstrate a smart home system integrating intelligent HVAC and lighting control with security and metering – all based on the EnOcean energy harvesting wireless standard but from different member companies. The demo shows an intelligent connected home which overcomes the limits of isolated building areas based on real-world applications. Visitors of the show can experience this cross-vendor smart home approach in hall 5 at booth H70.
The present trend for smart home solutions is bringing together the application areas comfort, security as well as energy and cost saving to an integrated, user-friendly system. The EnOcean Alliance offers its members a platform to develop products based on an open wireless standard (ISO/IEC 14543-3-10) and standardised application profiles which ensure the interoperability of all solutions. This approach allows users flexibly combining devices from different vendors for an optimized smart home system meeting their individual needs. The mutual basic technology of the EnOcean Alliance and its members is the EnOcean energy harvesting wireless standard, which enables batteryless wireless devices. They collect their energy from the surrounding environment such as motion, light and temperature differences and therefore work maintenance-free.
At the event, the EnOcean Alliance shows an integrated smart home system based on the EnOcean standard covering the following areas:
Heating, Ventilation, Air Conditioning (HVAC)
HVAC has an enormous potential for saving energy. After all, the heating system accounts for more than 70 percent of the delivered energy consumed in private households. Batteryless wireless automation is an attractive way to unfold the potential at minimum installation effort and costs. The demo system integrates a self-powered wireless temperature sensor fromThermokon, a CO2 sensor from AFRISO, an occupancy sensor, a window contact and aHORA wireless heating valve. Alternatively, users can choose a self-powered heating valve from Micropelt. These components are intelligently connected so that heat is only supplied when the room is occupied or the temperature needs to be adapted to a predefined set point. In addition, the valve automatically turns down the heating when the window is opened, whereas the CO2 sensor monitors air quality. The result is a comfortable and energy-saving living atmosphere.
Light can significantly influence a user’s mood and modify the perception of a room. Lighting in an intelligently connected home means automating dimming and switching based on external factors such as ambient lighting or the presence of persons. The demo shows how this can be realised by a batteryless wall switch from PEHA and light intensity sensor from Thermokon, switching and dimming plug receivers from permundo and Diehl Controls, an occupancy sensor and a PEHA handheld switch.
Security is probably one of the strongest motivations for a smart home as it’s a bare necessity for the user. It starts with basic features covered by a window contact and wirelessly connected window handle together with a ceiling mounted occupancy sensor. They trigger an alarm and a message to the user’s smartphone is sent if a window was opened or a person’s motion is registered in the house while the user is not at home. But smart security goes beyond a burglary alarm. AFRISO’s sensors and warning devices protect against leaks (e.g. water, oil, gas) or a too high humidity rate in the air. A smoke detector complements the system.
For energy and cost saving purposes, users need to know how much energy electrical devices consume and where the highest saving potentials are. The plug receivers from permundo andDiehl Controls allow for direct control and monitoring of lighting and electrical appliances to. They offer advanced monitoring of energy consumption, switching and metering functions and optionally also dimming capabilities with load-type detection. In addition, a batteryless wireless current transducer clamp can simply be clipped around any AC cable to measure the current flowing in a single mains conductor.
All of these smart home components wirelessly communicate with each other. The cross-vendor network of the complete automation system is realized by a central control unit to achieve highest comfort and energy savings. It centrally receives and processes all data from the distributed sensors and intelligently controls the functionalities. The result is an optimized integrated automation solution that takes the user’s individual needs and changing situations into account. At the booth, the EnOcean Alliance shows the wibutler Pro system from iExergyincluding an app for remote control, the modular multifunction smart home gateway fromAFRISO and the Smart Eco System central unit from Diehl Controls. Thanos, the design-orientated, multifunction room operation device from Thermokon, complements the selection of central control devices.
