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.
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.

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.
A single Koolmesh network can handle up to 500 devices. For larger projects, multiple networks can be linked together across buildings or campuses.
In a normal application, the number of Hytronik Bluetooth devices per network can be up to about 200 sensors + 400 receiving devices (nearly 600 devices in total). In applications where the motion sensors are not too often triggered, and daylight sensors are not set to be working everywhere and sending daylight information too often by everybody, the total amount of devices may succeed to 400 sensors + 600 receiving devices (a total of 1000 devices). However, it is fully depending on the installation environment and installation distance. Different Bluetooth nodes also can affect this capacity: the fewer motion sensors the larger the capacity. For larger projects, multiple networks can be linked together across buildings or campuses by using the “Multi-network gateway synchronous control" feature on Koolmesh app.
Koolmesh system supports offline commissioning. However, users must log in to the Koolmesh app and create a new network before performing offline commissioning onsite.
Because Koolmesh is a true mesh network, communication is shared across all devices. If one fails, the rest continue to operate normally.
Yes. Koolmesh supports integration with BACnet, DALI, and other industry standards, either on-premise or via the cloud.
Koolmesh is GDPR compliant and built with multi-layer security — from device encryption to secure cloud infrastructure. It is also aligned with upcoming EU and UK cybersecurity regulations.
Koolmesh provides dashboards, diagnostics, and predictive maintenance with D4i driver data. You can monitor energy usage, detect issues early, and reduce downtime.
Yes. Koolmesh is designed for professional projects of any size, from classrooms to factories, offices, hospitals, and multi-site campuses.
You’ll need Hytronik devices (drivers, sensors, switches) and the Koolmesh app (iOS, Android, or web). A gateway is optional for remote and cloud integrations.
We provide resources like video tutorials, documentation, and project support. For larger projects, our technical team can guide commissioning and integration.
