// What is OpenAIS ?

• OpenAIS is an EU co-funded project under the Horizon 2020 framework, Jan 2015 - Dec 2017. (Demonstrator operation and project finalization until June 2018).

• Project Partners are ARM, NXP, JCI, Zumtobel, Philips, Tridonic, Dynniq, TNO and TU/E.

• It aims at setting the leading standard for inclusion of lighting controls for professional applications into IoT. The project has a focus on office lighting, and will enable a transition from the currently existing closed and command oriented lighting control systems to an open and service oriented system architecture.

// IoT Success Factors

• Why should we use IoT at all? We already have DALI!

• The internet technology replaces heritage dedicated controls one after the other, so we better prepare for this!

• Why is internet technology so successful? The reasons are not obvious:

• It is more flexible and innovation friendly than ANY OTHER technology in controls

• It needs neither compatibility marks nor interoperability enforcements.

• This is technically achieved by a point-to-point communication architecture, that needs partner compatibility rather than system compatibility on each of the OSI layers.

5

// OpenAIS // ZVEI Consortium Day // Walter Werner // 2017-10-26 Werner Management Services e.U.

// Lighting Controls Success Factors

• Simple and cheap wiring requirements

• Simple and cheap interfacing requirements

• Low (controller and memory) resource demand at the final nodes.

• Available stacks and comparatively simple software requirements.

• Reasonable functionality (scenes, groups etc.) already inbuilt.

• This is achieved by a straight forward design, that bundles all the OSI layers AND the application into one.

6

// OpenAIS // ZVEI Consortium Day // Walter Werner // 2017-10-26 Werner Management Services e.U.

// Future Success Factors

• Cloud connectivity

• Lifetime adaptations of controls behavior (Controls as a Service)

• Lifetime adaptations to future UI und AI.

• Lifetime adaptations / interaction to BC, BM and FM Systems.

• Compatibility to AR and BIM

• Upgradeability of parts of the system with backward compatibility to the remaining.

• Seamless integration of heritage systems (whatever is considered heritage at any moment in time)

• Operational resilience and graceful degradation design

• Ease of system install, operation and maintenance

// OpenAIS // ZVEI Consortium Day // Walter Werner // 2017-10-26 Werner Management Services e.U.

// Main OpenAIS Challenges

• Integrate wired, PoE, wireless and heritage systems to a seamlessly operating system. Achieve full scalability across technologies.

• Allow for low latency and high synchronicity user interaction in low bandwidth IP based systems: • „switch 100 light points on meshed RF to new (scene)

settings within 200ms“.

• Ease the electrical contractors tasks (for all types of systems).

• Allow for disconnected small and stupid systems that can be upgraded / integrated into larger and full blown settings later.

• Balance „interoperability“ and „vendor differentiation“.

8

// OpenAIS // ZVEI Consortium Day // Walter Werner // 2017-10-26 Werner Management Services e.U.

// Achieving Low Latency

• All Internet communication is 1:1. This results in „one after the other“ when addressing multiple nodes. With serial processing the timing for switching larger numbers of light points turns out too long.

• IPv6 provides „multicast“, a communication that allows to address multiple nodes in parallel, using a single communication. However, some of the necessary surrounding technologies are not (yet) there:

• Securing multicast messages with low latency is tricky.

• Acknowlegement messages need to be prevented from piling up and blocking the communication band, especially when using multiple multicast messages within a short timeframe (e.g.: start, continue and stop dimming) for a larger number of listeners.

9

// OpenAIS // ZVEI Consortium Day // Walter Werner // 2017-10-26 Werner Management Services e.U.

// Integrate the Diversity

• The use of CoAP (also for multicast) allows application of the system across all the PHY diversity, using transparent „border routers“ between the technologies.

• Application layer gateways may be used to integrate heritage systems like DALI. (However, integration deficits remain)

• Some nodes will host more than one light point. OpenAIS group definition allows to address each light point, and provides means to address a group through a mixture of unicast and multicast addresses to adapt to network variants and to provide accessibility to „hidden behind a router/firewall“ members.

• A Sensor-Control-Actuator messaging path allows to (completely) respecify the control activity at any time without changing the firmware of the lighting or sensing nodes. Controls may be placed peripherally (at the luminaires) or centrally (at a server or in the cloud) or in a mix thereof.

• Processing and arbitration of conflicting signals from multiple controllers are handled through multiple instances of the Interfacing Objects. Groups control is using the same interfacing objects, this way allowing to control a group „as a single actuator“.

• User interfacing (together with security and access management etc.) is positioned at the (group) control objects, keeping the effort (security, access management etc.) at the final nodes as small as possible.

Application..

..

Application focus: IPSO objects are complemented by openAIS Objects, supporting some features needed for professional lighting controls

Middleware: OpenAIS supplies the resultsto fairhair (and others) to allow creation ofstacks for building controls beyond lighting.The OpenAIS Demonstrator system is basedon LWM2M and mBed.

Network: OpenAIS uses the Ethernet standard(s) and collaborates with the Thread group for the demonstrator system.

IoT and OGC collaboration in OpenAIS:IoT Architecture:

Additional benefits:- low latency- resilience- support for small & simple systems

// OpenAIS // ZVEI Consortium Day // Walter Werner // 2017-10-26 Werner Management Services e.U.

// The Results are here!

• The OpenAIS Demonstrator will be operational in January 2018.

• This is the world’s first working, scaleable and fully IoT based lighting controls that achieves low latency.

• Within 3 years research, architecture definition, system design and the realization of hard- and software have been developed in a joint effort by a perfectly cooperating team. This is a unique success story.

• Demonstrator system comprises some 400 light points, 800 sensor objects, 140 groups with diverse controls functionality, and includes User Apps and BMS integration. This is realized in an open and group office environment, with a real customer (The public health service of Eindhoven).

• OGC (the OpenAIS Group Communication) are announced to be used by fairhair, dot-dot (and possibly other ecosystems) for their future success.

• Finalize and deploy demonstrator firmware, install luminaires.

• Commission and operate the system

• Research the demonstrator performance

• User Interfaces

• Functionality, latencies, user satisfaction

• Create final set of documents.

• Identify path into standardization and exploitation.

15

// OpenAIS // ZVEI Consortium Day // Walter Werner // 2017-10-26 Werner Management Services e.U.

// This is just the Begin

• Open IoT based controls will provide diversity with interoperability.

• Customer and manufacturer interest will increase slowly, but with massive force.

• Diversity in (lighting) controls and ecosystems will increase. IoT technology allows to accept mixed deployments.

• IoT provides the means for multiple connectivity. Future nodes may talk more than one control language concurrently, and additionally listen to OGC signals for immediate reaction.

• A small number of standardized low-latency group commands (e.g. dim, switch, presence, scene recall), that can be used across all ecosystems will enable the internet success parameter also for IoT based lighting.

• It is up to you to adopt the future early or suffer from coming (too) late. OpenAIS resolved the basic technical challenges for you.
