RGBWW Spots Connected to Loxone Miniserver via DMX Extension
This blog post is based on a Dutch client's sharing of an RGBWW Spot connect Loxone via DMX. The client has authorized TILLUME to publish this blog post.
As an IT professional and DIY enthusiast, lighting was an important part of my renovation. With 77 spots throughout the house, I knew one thing for sure: I wanted a flexible and affordable system, without being completely dependent on a single manufacturer. The standard Loxone solution was an option, but the costs quickly added up.
That's why I delved into the world of alternatives and found the perfect combination: powerful RGBWW spots that I control via the DMX protocol with my Loxone system. In this blog, I'll explain step by step how I approached this, which materials I used, and why this is the ideal solution for me.
The Spots: Atmospheric and Flexible with RGBWW
The basis of my plan is the RGBWW spots. This abbreviation stands for Red, Green, Blue and Warm White, all integrated into one compact spot. They run on 24V and, with approximately 400 lumens each, provide a beautiful light output. This makes them ideal for creating different atmospheres in every room: from bright white work lighting to a cozy, warm glow for the evening.
The Control: Stable and Local via DMX
How do you control these spots? I use a DMX512 LED controller. This controller is connected directly with a cable to the Loxone DMX Extension. The great advantage of this is reliability: no hassle with Wi-Fi signals or dependence on a cloud service. Everything runs locally and stably via a wired connection.
In theory, you can connect up to 30 spots per controller, but in practice, that's more than you need for one zone. For example, I have 24 spots on the ground floor, divided into 4 zones. That means I also use 4 separate controllers for maximum flexibility.
The Wiring: A Solid Foundation
A good installation starts with the right wiring. Below, I explain how I connected everything.
Power Supply and DMX Signal
Two types of cables run from the meter box to each DMX controller:
Power cable: For the 24V power supply of the controller, I use a 2-core speaker cable of 1.5 mm².
DMX signal cable: For the DMX signal, I use a standard CAT6 network cable.
On the controller side, I crimp a standard RJ45 plug onto the network cable (according to the TIA-568B standard). You plug this into the DMX controller.
On the other end, at the Loxone DMX Extension in the meter box, you connect the cores of the network cable as follows:
Orange/white → DMX + terminal
Orange → DMX - terminal
Brown & Brown/white (together) → GND (ground) terminal
This configuration ensures a trouble-free and stable connection.
Wiring from Controller to Spots
To connect the spots to the DMX controller, I use a 5-core control cable, which makes connecting very easy. The black wire on the spot is the positive (+).
I use the following scheme:
Core 1 → Red (R)
Core 2 → Green (G)
Core 3 → Blue (B)
Core 4 → Warm White (WW)
Yellow/green core → Black wire (+) of the spot

Test Setup in Action 🎬
During testing, I set up an installation to check the control via DMX. In the video below, you can see how smoothly it works:
Why I Choose This Method
Cost-effective: Significantly cheaper than the official Loxone lighting products.
Reliable & Local: No internet or cloud needed. Everything works in-house.
Seamless Integration: Works perfectly with the Loxone system.
Optimal Flexibility: RGBWW gives you all colors and beautiful warm white light.
Scalable: Easy to expand by adding extra zones with controllers.
