How do smart lighting
controllers work?

Smart lighting controllers are a key element of modern systems for managing luminaire operation and energy consumption in cities. They enable process automation, real-time monitoring, and energy optimization with per-luminaire precision.

By using controllers connected to a central management system, you can:

  • monitor the behavior of all luminaires down to each individual fixture
  • automate on/off switching and dimming level control
  • supervise electricity consumption
  • monitor alarms
  • create flexible functional groups fully independent of power grid topology

Additional benefits are achieved by extending controller functionality with external sensors:

  • detect pedestrian and vehicle movement,
  • adjust lighting levels to weather conditions and traffic intensity,
  • send data to the central management system.

Controller types and communication standards

Control protocols

ZHAGA D4i

DALI D4i

Digital, bidirectional communication enabling precise lamp control and monitoring.

0-10V

Analog light-level control system.

Communication technologies

RF Mesh

Each lamp is connected with others to form a reliable smart-lighting network. Very high security, high communication throughput, and unlimited transmission frequency enable a second autonomy layer (fog computing).

GSM

Controller-to-central-system communication without intermediate elements. Transmission uses licensed spectrum supervised by a telecom operator, ensuring the highest possible security level.

LoRaWAN

Low power consumption, long range, low data throughput, and significant limits on transmission frequency.

Modern iBLOC and eBLOC controllers

eBLOC controller

The eBLOC family of external controllers includes smart devices equipped with a broad set of additional functions.

Key device capabilities:

ZHAGA D4i

Zhaga connector

Controller variant compatible with ZHAGA sockets compliant with Zhaga Book 18.

NEMA connector

NEMA connector

Controller variant compatible with a NEMA 7-pin connector.

LTE-M or NB-IoT communication

Direct cloud communication using WAN networks.

Radio communication (Thread 2.4 GHz)

Reliable connection with the management platform, lower data transmission costs, and follow-me lighting support. Local mesh communication gives more flexibility in deployment.

DALI icon

Support for DALI, DALI2, and D4i drivers

Precise brightness control and bidirectional communication with luminaire drivers through modern digital interfaces.

Support for 1-10V drivers

Questions and answers

A controller (e.g., eBLOC Zhaga or Nema) is a small device installed in a lighting luminaire. It is the lamp "brain" - it executes commands from the system (e.g., "dim to 30%"), monitors its status (energy consumption, faults), and communicates with the Urban system.
If luminaires are new and have NEMA or Zhaga sockets, installation is very fast (plug-and-play). When modernizing older lamps, installation may require an electrician to work inside the luminaire, but often the entire luminaire does not need to be replaced.
Simply scan the QR code using the mobile app; the luminaire without control or the controller will be assigned to a location on the map, or according to previously prepared inventory. LTE controllers with a GPS receiver can appear on the map automatically.
Depending on the device manufacturer, it can be accurate to <1% (LUG controllers) for NEMA controllers that have a measurement transducer installed inside. The accuracy for ZHAGA controllers depends on LED drivers that provide this information to the controller according to the D4i standard.
It depends on the location and project requirements. The Thread (Mesh) variant is ideal for dense urban areas, does not require many SIM cards, and enables responsive lighting. The LTE variant requires a SIM card in each controller and works well as a complement to the mesh variant in locations where single points must be installed.
Some controller versions (e.g., LTE variant) have a built-in GPS module. This means that after installation the controller determines its position and automatically appears in the correct place on the map in the Urban system.
