3 Development flow

Creative process Creating process Delivery process Connectivity in lighting

• Why? – Business case and Added value? • Maintanance • Control • Usability • How? – Wired vs Wireless? – Integrate existing standard?

5 Complexity2

6 Challenges of connected lighting

• Connected: – Luminaires – Swiches – sensors • Multiple platform interface – Switch (sensor, user) – App/cloud/website – Other • Gateway to: – Internet – Smartphone – Building management system – Other

7 What kind of networks?

• Network types – Point to point – Mesh – Star – Ring – Bus

8 Selection criteria

• Important to make good use cases – Focus from customer point of view – Problem domain, not solution domain • Who uses the product • How is a product used • What if (a part of) the interface fails – This will also create explicit and necessary input for agile development

9 Wired or wireless?

• There is no “one size fits all” • Criteria: – New or existing infrastructure – Data rate – Power requirements – Professional or domestic application

10 Wireless technologies

• WiFi • • Zigbee • 6LoWPAN • Myrianed • Other protocols

11 Wifi

• Wi-Fi, is a local area wireless technology that allows an electronic device to exchange data or connect to the internet using 2.4 GHz UHF and 5 GHz SHF radio waves. • The Wi-Fi Alliance defines Wi-Fi as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards“.

Pro Con High data throughput Power consumption Worldwide standard Unit price Dependency on 3rd party access points High software maintenance cost

12 Bluetooth 4.0

• Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices. It can connect several devices, overcoming problems of synchronization. • The Smart Mesh study group has been created to define the Feature Requirements for a Smart Mesh networking within the Bluetooth SIG. It is expected that the initial FRD will concentrate on lighting.

Pro Con Low power Limited range Smartphone compatible Gateway needed for internet connection Upcoming mesh networking Limited bandwith Additional functions (Beacon)

13 Zigbee

• ZigBee is a specification for a suite of high-level communication protocols used to create personal area networks built from small, low-power digital radios. ZigBee is based on an IEEE 802.15.4 standard. Though its low power consumption limits transmission distances to 10–100 meters line-of- sight, depending on power output and environmental characteristics, ZigBee devices can transmit data over long distances by passing data through a mesh network of intermediate devices to reach more distant ones.

Pro Con Mesh networking Heavy stack (>60Kb) Almost no inter operability Gateway needed for outgoing connection Issues if mesh > ~40 pieces (latency)

14 6LoWPAN

• 6LoWPAN is an acronym of IPv6 over Low power Wireless Personal Area Networks. • The 6LoWPAN concept originated from the idea that "the Internet Protocol could and should be applied even to the smallest devices,“ and that low- power devices with limited processing capabilities should be able to participate in the Internet of Things.

Pro Con IP adress for all nodes Same heavy stack as Zigbee (IEEE 802.15.4) Backed by Google Backed by Google

15 Myrianed

• MyriaNed is a (WSN) platform developed by DevLab. It uses an epidemic communication style based on standard radio broadcasting. This approach reflects the way humans interact, which is called gossiping. Messages are sent periodically and received by adjoining neighbors. Each message is repeated and duplicated towards all nodes that span the network, it spreads like a virus (hence the term epidemic communication).

Pro Con Mesh networking No major companies involved (yet) Self organising Build by FHI members

16 other

• Other wireless standards – WirelessHART – DASH7 – EnOcean – Z-Wave – Etc… – Proprietary

17 Wired technology

• Dali • Ethernet Pro Con Fixed Material cost • KNX connection • CAN Many options Complex installation • RS485 • Etc…

18 DALI

• A DALI network consists of a controller and one or more lighting devices (e.g., electrical ballasts and dimmers) that have DALI interfaces. The controller can monitor and control each light by means of a bi-directional data exchange. The DALI protocol permits devices to be individually addressed and it also incorporates Group and Scene broadcast messages to simultaneously address multiple devices (e.g., "Group 1 goto 100%" or "Recall Scene 1").

Pro Con Simple protocol Limited number of devices (<64) Low cost components

19 Ethernet

• A DALI network consists of a controller and one or more lighting devices (e.g., electrical ballasts and dimmers) that have DALI interfaces. The controller can monitor and control each light by means of a bi-directional data exchange. The DALI protocol permits devices to be individually addressed and it also incorporates Group and Scene broadcast messages to simultaneously address multiple devices (e.g., "Group 1 goto 100%" or "Recall Scene 1").

Pro Con Well known protocol Heavy software and hardware requirements IP communications Power over ethernet

20 KNX

• KNX is a standardized (EN 50090, ISO/IEC 14543), OSI-based network communications protocol for intelligent buildings. KNX is the successor to, and convergence of, three previous standards: the European Home Systems Protocol (EHS), BatiBUS, and the European Installation Bus (EIB or Instabus). The KNX standard is administered by the KNX Association.

Pro Con ~ 350 member companies Complex installation Many COTS components Licencing model by KNX association

21 There will always be cables

In the foreseeable future wires are needed for power anyway

What will the future bring? • Bottom up architectures will prevail • Replacement of 240V infrastructure? • All products will become intelligent and connected

22 checklist

Connected lighting, what do you need:  Application  Use case(s)  Network type  Wired or wireless  Communication protocol

23 What can Metatronics do for you?

• Create full service hybrid systems – Led solutions – Sensor solutions – Human interface solutions – Networking solutions (both wired and wireless)

24 Example

Therapy luminaire • Dual platform interface (product and app) • Minimal interface on product, all intelligence in app • Single touch solution on product – Top of product is touch sensitive.
