ComfortClick bOS KNX Server

Introduction

The ComfortClick bOS Server (often referred to as ComfortClick or simply bOS) is one of the most powerful KNX servers in the market. Unlike traditional KNX visualization servers that only focus on KNX, bOS takes a universal approach to smart home automation, offering multi-protocol integration in a single platform.

It is a software-first server, meaning it can run on dedicated ComfortClick hardware like Jigsaw, Grinder, Colibri, or even on standard Windows/Linux PCs and virtual machines. This flexibility makes it very popular among integrators who want a single server that handles KNX, Modbus, BACnet, Zigbee, Z-Wave, Sonos, Philips Hue, Nest, Alexa, Google Home, and many more.

In this review, we’ll cover the features, setup, integrations, pros & cons, and comparisons of bOS for KNX projects.

What is ComfortClick bOS KNX Server?

The ComfortClick bOS (Building Operating System) is an open integration platform that supports KNX and dozens of other smart home and building protocols. It allows:

Visualization – Fully customizable dashboards.
Automation – Advanced logic and event handling.
Integration – Connect KNX with third-party IoT and building systems.
Voice & Cloud Control – Alexa, Google Assistant, Siri shortcuts.
Energy Monitoring – Real-time data collection and reports.

This makes ComfortClick a Swiss Army knife of servers, suitable for residential, commercial, and even hospitality projects.

ComfortClick vs Other Servers

Vs Gira X1 – Gira is simple and KNX-only; Comfort-Click supports multi-protocol integration.
Vs Basalte Core – Basalte focuses on luxury UI; Comfort-Click focuses on customizability and flexibility.
Vs Thinka – Thinka is strong in KNX-to-HomeKit/Alexa integration; Comfort-Click is a full building OS.

Vs BAB EIBPORT – EIBPORT is powerful in professional automation; Comfort-Click has a friendlier UI with wider integrations.

Best Use Cases

Residential luxury homes – Custom visualization, integration with AV and IoT.
Commercial offices – Energy monitoring, KNX + Modbus + BACnet integration.
Hotels & hospitality – Scalable server (Grinder/Sledgehammer) for room control + guest experience.
Hybrid projects – Where KNX must connect with IoT (Hue, Sonos, Spotify, Nest, etc.).

Conclusion

The ComfortClick bOS Server is not just a KNX server – it is a complete smart building platform. If you want multi-protocol support, customizable dashboards, and scalability, ComfortClick is one of the best choices available.

For pure KNX-only projects, simpler servers like Gira X1, ABB ControlTouch, or Iddero may be easier and cheaper. But if you want a future-proof, highly flexible, and integrator-friendly solution, ComfortClick is an excellent investment.
