Easy Setup & Full Features
Commission projects quickly with a clean, minimalist interface. From simple daylight on/off thresholds to complex schedules and linked scenes, Koolmesh covers every technical need without complexity.


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.

Open Standards & 3rd-Party Integration
Built on global standards including Bluetooth SIG Mesh and Bluetooth NLC, Koolmesh ensures long-term compatibility. It can run stand-alone, connect on-premise with BACnet, or scale through cloud integrations.
How Koolmesh Works?
Koolmesh is built on Bluetooth SIG Mesh and Bluetooth NLC — proven global standards that make every device part of a smart, self-healing network. This means your lighting system stays reliable, flexible, and scalable without the cost or complexity of wired control.

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 reach 400 sensors + 600 receiving devices (a total of 1000 devices). However, it is fully dependent 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 the 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.
