Transcription

1 Implementing a Standard, Multi-Gateway: Real SmartHome in the Cloud Dr. Michael Westermeier Product Manager RWE SmartHome European Utility Week, Amsterdam, RWE Effizienz GmbH, European Utility Week, PAGE 1

2 Energy economy is changing New regulatory framework New competitors New customer demands New technology RWE Effizienz GmbH, European Utility Week, PAGE 2

3 From energy supplier to energy manager: Offering solutions for home energy management Core business Activity of the RWE Effizienz GmbH gas electricity Homeautomation Decentral power generation Prosumer heat Smart Meter Energy services Electromobiliity RWE Effizienz GmbH, European Utility Week, PAGE 3

4 RWE SmartHome: Energy efficiency combined with comfort and security Controls heaters according to Switches your electrical Switches and coordinates your Uses remote control, also via Central control and configuration Measures and shows PV generation, user demand devices lighting smartphone via PC energy storage and consumption RWE Effizienz GmbH, European Utility Week, PAGE 4

5 RWE SmartHome until 2012: Proprietary and closed, but reliable architecture PC Control from anywhere RWE Backend Central control unit SmartHome Controller In-House control PC Smartphone Encryption Sender Smart Switch Remote controller Actuators Radiator thermostat Smart switches Configuration Authentication Additional information Internet, Certificates Database Smokedetectors Motion detector Door-/ Window-sensors Sensors Virtual resident Sunrise/ Sunset-App, etc. Apps/ Services... allows energy savings, comfort and security information/ control RWE Effizienz GmbH, European Utility Week, PAGE 5

6 RWE SmartHome from 2013 on Relying on proven and stabilized RWE SmartHome architecture Offering modular concept with app-approach and APIs Integrating third party devices in strong partnerships Realizing stepwise the internet of things Based on new (RF-) communication protocol RWE Effizienz GmbH, European Utility Week, PAGE 6

7 Internet of things What is that, how far are we? Everyone talks about internet of things Many directly internet-ready devices already exist today Mainly complex devices (e.g. smartphones, PC, tablets) Very rarely simple things like SmartHome devices How can things become internet-ready? RWE Effizienz GmbH, European Utility Week, PAGE 7

8 The gap between internet of things and SmartHome appliances Internet XML Http TCP/IP Web services Plug and play Interoperable SmartHome protocols Many existing protocols (ZigBee, Z-Wave, KNX, Modbus, ) Byte oriented communication Mostly proprietary Not interoperable RWE Effizienz GmbH, European Utility Week, PAGE 8

9 Internet-readyness: Much more than just IPv6 IP communication is a well established internet standard Address range problems were solved by IPv6 introduction Physical layer of communication is not the relevant parameter Wireless and/or cable communication concepts should not restrict ideas and should be transparent at IP level Security Layer: AES 128 with RSA key exchange well established Main challenge: Interoperable, standardized application language RWE Effizienz GmbH, European Utility Week, PAGE 9

10 Main challenge: Application layer Usage of only one internet language: no translation, no middleware, no byte-oriented language Use of direct internet standards (XML plus XSD) XML can be easily compressed by EXI in RF communication Generic approach is needed for future proven applications SmartHome devices should be self-descriptive and service oriented RWE Effizienz GmbH, European Utility Week, PAGE 10

11 What is the aim of RWE? RWE actually develops an Internet- SmartHome protocol It is based on the mentioned standards and prerequisites The protocol is established within a strong partner alliance Alliance for standardization of the protocol is intended The protocol will focus mainly on application-layer Service oriented, self-descriptive approach This protocol enables the future perspective for a completely cloud based SmartHome intelligence RWE Effizienz GmbH, European Utility Week, PAGE 11
