Crestron Aims Zūm at App-Based Lighting Control

Crestron announces Zūm (pronounced "ZOOM"), a package of essential "building block" devices for the design, setup and management of app-based lighting control in any space.

The Zūm system includes wireless dimmers, switches and sensors, all engineered to work together wirelessly. Setup requires a few taps on a keypad, dimmer or mobile app, and a single load controller supports up to 32 devices. Each device has a wireless range of 45m in every direction, and mesh networking allows communications to hop from one device to the other, with no need for interface boxes or antennae.

The system can from standalone systems to centralised building-wide control and network management in "literally a snap," since the Zūm network bridge "snaps" into a Zūm load controller to add remote setup, daylighting, time clock scheduling, temporary overrides and other advanced capabilities.

A Universal Language for the IoT

A Universal Language for the IoT

The ZigBee Alliance takes to CES to unveil Dotdot-- a "universal language" for the devices making the Internet of Things (IoT), first seen at the show running over a Thread IP-based network.

As announcement release puts it, the majority of IoT devices do not "speak" the same language, even if they use the same wireless technology. This leads to arguably needless complexity for developers, while limiting customers to single-vendor systems. Enter Dotdot, an application layer at the heart of ZigBee technology developers can apply across other IoT networks.

Bluetooth 5 Officially Adopted

The Bluetooth Special Interest Group (SIG) gives the final stamp of approval to Bluetooth 5 as the latest version of the wireless networking standard-- one with longer range, faster speed and larger broadcast message capability.

Specifically, Bluetooth 5 promises up to x4 the range, x2 the speed and x8 the broadcast message capability compared to the previous version. As a result it should be able to power whole home and building coverage, enable more responsive, high-performance device and allow for more context relevant solutions. Also included are updates helping reduce potential interference with other wireless technologies, allowing it to coexist with other networking standards within the Internet of Things (IoT).

LuxLive Tests Li-Fi Networking

LuxLive Tests Li-Fi Networking

LuxLive 2016 sees the world's first test of li-fi, the lighting-based networking system developed by Scotland-based pureLiFi, in a live setting-- one featuring the streaming of a video to a tablet.

The li-fi system was connected to the tablet via USB. When Harald stood directly under the Power over Ethernet (PoE) adapted stage lights, a network was quickly detected, although the signal soon started to fade as he moved further from the lights. This means the technology, at least so far, still has a short range. In fact, each li-fi lighting fixture has a range of sixty degrees and 7-8 square metres, and as such multiple enabled luminaires need to be used to widen available coverage.

"Wireless communication is lacking frequency," pureLiFi's Dr. Harald Burchardt tells LuxReview. Li-fi technology has the ability to widen the capacity of our wireless communication options."

More Security for Z-Wave Certified Devices

The Z-Wave Alliance adds a further security requirement to the Z-Wave certification-- the new Security 2 (S2) framework requires the adoption of strongest levels of IoT security in the industry.

According to the alliance, the S2 framework provides the most advanced security for smart home devices and controllers, gateways and hubs, and will be mandatory for all products receiving Z-Wave certification after 2 April 2017. Developed in conjunction with cybersecurity hacking experts, S2 promises new levels of impenetrability by securing communications both locally for home-based devices and in the hub or gateway for cloud functions.
