Koolmesh: The Wireless Lighting Control System for Professional Projects



Built on global standards like Bluetooth SIG Mesh, Bluetooth NLC, and DALI

Koolmesh is the professional system by Hytronik — a high-quality, affordable alternative to Casambi, Wirepas, or DALI+, fully integrable with BMS platforms

Discover how Koolmesh works — and how you can use it in your next project

  • No license fees
  • No hidden costs
  • Create and manage lighting scenes easily in schools, offices, industry, or any large building project
  • Just a powerful wireless platform that brings luminaires, sensors, and switches together into one reliable mesh

Why Wireless Lighting Control Matters



For years, wired control systems dominated the market. They were powerful — but also expensive, complex, and slow to adapt. Many companies built their success on cables, only to be outpaced by competitors embracing wireless.

What you can do with Koolmesh and your lighting


Commission All Your Lighting Devices Wirelessly and Easily

You can create the exact lighting behaviour your project requires — from a simple daylight on/off threshold to complex schedules and scenes.

Clean and minimalist interface that turns commissioning into a fast and intuitive process.
Flexible, reliable, and affordable, it gives facility managers, building owners and end-users full control without the cost and complexity of wired systems.



Dashboards & Heatmaps

Turn sensor and driver data into actionable insights. Visualize energy use and occupancy through heat maps, measure real powerline or DALI driver consumption, or work with smart estimations.

Multi-Device Access

Use the Koolmesh app on both Android and iOS for on-site commissioning. Add the web app for remote management and full project overview.

Third party integrations with Koolmesh BACnet enocean Shelly Terabee D4i NLC

Open Standards & 3rd-Party Integration

Built on global lighting standards like Bluetooth SIG Mesh and Bluetooth NLC, plus DALI-2 and D4i to ensure long-term compatibility.

Third-party integrations extend capabilities beyond lighting:

  • People counting & flow – Terabee
  • Real power metering – Shelly
  • Wireless push buttons – EnOcean
  • BMS integration – via API and BACnet





Emergency Control

Automate all functional and duration tests. Keep emergency lighting installations fully compliant and reporting-ready for any incident.


Remote Control

Adjust parameters, update scenes, and troubleshoot without traveling to site. Remote access reduces downtime and simplifies maintenance — full remote commissioning is our next milestone.


Predictive Maintenance

Koolmesh is fully compatible with D4i drivers (Parts 251–253). Capture and store data on asset management, energy usage, diagnostics, and maintenance to anticipate issues before they happen.

FAQs — Your Koolmesh Questions Answered

Got questions? Check out our most common Koolmesh queries.

1. How does Koolmesh differ from wired lighting systems (like DALI or KNX)?

Koolmesh eliminates the need for expensive cabling and complex commissioning. It offers the same professional features as wired systems, but with faster setup, lower costs, and easier scalability.

2. How many devices can I connect in one project?

A single Koolmesh network can handle up to 500 devices. For larger projects, multiple networks can be linked together across buildings or campuses.

3. Does Koolmesh need internet to work?

Koolmesh supports offline commissioning. However, users must log in to the Koolmesh app and create a new network before performing offline commissioning onsite.

4. What happens if one device fails?

Because Koolmesh is a true mesh network, communication is shared across all devices. If one fails, the rest continue to operate normally.

5. Can I integrate Koolmesh with existing building systems?

Yes. Koolmesh supports integration with BACnet, DALI, and other industry standards, either on-premise or via the cloud.
