Invisible Gateway for Smart Street Lighting

Tvilight SkyHub brings the RF Mesh gateway directly onto the luminaire. Its compact Zhaga form factor integrates seamlessly into the lighting infrastructure, delivering gateway connectivity without a separate gateway enclosure or installation.

SkyHub connects the local RF Mesh network with CityManager or a compatible third-party management platform. It also functions as an individual luminaire controller, controlling and monitoring the luminaire on which it is installed.

Through DALI-2, SkyHub supports compatible DT7, DT7, and DT8 drivers. The result is a clean, compact 2-in-1 solution for smart street lighting.

Zhaga RF Gateway One Device, Two Essential Roles

2-in-1 Gateway + Controller

SkyHub combines two essential functions within one Zhaga-mounted device.

As a gateway, it coordinates communication between the local lighting network and the management platform. As a controller, it manages and monitors the luminaire on which it is installed.

This integrated design simplifies the system architecture, reduces visible infrastructure and makes gateway virtually invisible to the public.

Scalable RF Mesh Communication

A single SkyHub can coordinate up to 200 compatible street light controllers over a secure 2.4 GHz RF Mesh network based on the global IEEE 802.15.4 standard.*

The self-forming, self-healing network creates multiple paths and dynamically selects best available routes for reliable communication.

* The gateway-to-controller ratio depends on the installation environment and network design.

Zhaga RF Gateway Connected Through Cellular Networks

Connected Through Cellular Networks

LTE Cat 1 connectivity enables SkyHub to exchange lighting data, alarms and commands with CityManager or a compatible third-party platform.

GSM/GPRS support provides additional communication flexibility across different markets and network environments.

Designed for Continued Local Operation

SkyHub supports the configuration, commissioning and maintenance of a stand-alone RF Mesh network.

Stored switching and dimming profiles can continue operating locally during a temporary interruption to the platform connection, helping the lighting installation maintain its intended behaviour.

Zhaga RF Gateway Smart Control at the Gateway-Luminaire

Smart Control at the Gateway Luminaire

Through DALI-2, SkyHub switches and dims the connected luminaire, with support for DT6, DT7 and DT8 drivers.

With a D4i driver, it retrieves energy, health, fault, asset and performance data to support efficient monitoring and better-informed maintenance planning.

Ready for Adaptive Lighting

SkyHub works with compatible Zhaga D4i motion sensors to support light-on-demand and neighbour-triggered lighting.

When activity is detected, selected lamps can increase their brightness according to predefined rules. During quieter periods, the lighting returns to its scheduled or predefined level, helping reduce energy use and unnecessary nighttime illumination.

Zhaga RF Gateway Flexible Lighting Profiles

Flexible Lighting Profiles

SkyHub supports autonomous, AstroClock and calendar-based switching and dimming.

Lighting behaviour can be configured around sunset and sunrise, operating hours, seasonal requirements or site-specific schedules. This allows each installation to balance energy performance with visibility and operational needs.

Customer feedback

“We wanted to accomplish a few things, namely reducing energy consumption at the stations and lowering light pollution for people living in the area. At the same time, we wanted to ensure public safety. Tvilight’s solution combined this beautifully.”

Eelco KrakauContract Manager, Dutch Railways

“JCL is using the Tvilight solution in County Kerry, which is the first installation of its kind in Ireland. The solution has proven to be very successful, enabling us to achieve 60% savings on energy. It’s a very impressive technology.”

Philip CurneenDirector and Program Manager at JCL

“Tvilight’s adaptive lighting control is an excellent solution; it has allowed us to save energy as well as manage the street lights remotely. I truly believe that this is the future for the Netherlands, Europe and the world.”

Robin BrekelmansProject Manager, Municipality of Nuenen

“I am really satisfied with the result. By using LED streetlights and dynamic dimming, we save more than 60% of the energy previously spent on street lighting. This is a major achievement.”

Stephan KikkertProject Leader, Municipality of Texel

“The beauty of the TVILIGHT solution is that it doesn’t compromise public safety in any way. The true light-on-demand helps to keep the streets safe while minimizing the light pollution.”

Haye MensonidesCommercial Director of Dynniq

“Technology is developing rapidly within public lighting. That’s why we choose Tvilight intelligent street lighting solution that is future-proof. Connected lighting will play a central role in the future.”

Sander KlijnstraMunicipality of The Hague

“The combination of new LED streetlights, dynamic dimming, and remote control options offered by TVILIGHT is an optimal investment because it helps us save energy while improving public safety and security at the port.”

Bas van den BoschProject Manager, Port of Moerdijk

“Classic streetlight design and integrated intelligence do not have to be mutually exclusive. We combined classic streetlight design with Tvilight’s wireless lighting control options to help The Hague meet its unique goals.”

Pieter VisserAccount Manager at DE NOOD

“Tvilight: The 'talking' streetlamps that will lighten your heart (but not your wallet). It is a first step to Smart Cities...”

Daisy CarringtonCNN

“We aim at becoming a Digital City with greater connectivity and information access for the citizens as well as the tourists. With intelligent lighting solution, this vision became a reality. Our city is benefiting in every aspect – from safety and security, to easy access to information.”

Shikhar AgrawalGovernment of Rajasthan

“Many youngsters visit the cinema, the skating ring, sports facilities and pubs during late evening hours. Sometimes they move in group, but often alone, and then good lighting is essential for a better sense of safety. This is an excellent initiative for the bicycle highway.”

Abdrahman LabsirCity Council Member at Youth and Prevention (Mechelen)

“Wireless smart lighting system was selected as most the preferred solution. It improves illumination and safety, reduces cost and cuts CO2 emissions. Due to the system’s openness and flexibility, it also offers a foundation to host innovative systems that would help us become a smart city.”

City of Dortmund

“Individual light management and control provide unprecedented flexibility. Performance of all the street lights is clearly visible in the light management system. Together with smart monitoring, this provides an unprecedented degree of transparency for the operator of the installation. This is what future smart light looks like today!”
