Smart control of public lighting
When grid operator Liander started phasing out the TF signal, municipalities across the Netherlands had to find an alternative for switching public lighting. For the Municipality of Nijmegen, this required a solution that could be implemented quickly, without losing flexibility for future developments. “We already knew Intemo from previous projects,” says Gerald van Meijgaarden. “When the TF signal was phased out, we needed a solution that worked immediately, but could also grow with us over time.”
When speed and budget come together
The municipality had already identified a technically suitable solution, but this option proved too costly at a time when budget constraints were a key factor.
At the same time, there was no room for delay. Public lighting had to remain operational, while the underlying system was changing.
“We needed to act quickly,” Gerald explains. “So we asked Intemo to develop a temporary solution that would not become obsolete, but could be expanded into a more intelligent system later on.”
A practical solution with room to grow
Intemo developed a configurable astronomical switching solution, designed specifically for this application. The system includes multiple switching outputs and a Modbus connection, allowing integration into a broader infrastructure.
Around 300 of these CityZenZ modules have been deployed in Nijmegen. They are used to control evening and night lighting, as well as to manage traffic-related installations.
The key advantage lies in its modular setup. The system can be expanded step by step with additional intelligence, without replacing the existing hardware.
“This way, we didn’t have to invest in a full system upfront,” Gerald says. “At the same time, we ensured that our initial investment remains valuable.”

Towards intelligent public lighting
The long-term goal for Nijmegen is to manage public lighting based on real-time conditions rather than fixed schedules. Together with Intemo, the municipality is working towards a system where lighting is controlled based on measured light levels.
Additional modules enable wireless communication with a central light sensor. This allows lighting to switch dynamically, while maintaining a fallback to the original system in case of signal loss.
The system can also be extended with monitoring capabilities, such as power consumption and cabinet status, all managed through a central platform.
A solution that evolves over time
For the Municipality of Nijmegen, the collaboration with Intemo is not about delivering a one-time solution, but about building a system that can evolve.
By starting with a practical and reliable foundation, and expanding it step by step, the municipality remains flexible while maintaining control over costs and performance.
