Fibaro RGBW in a pendent light or the Wofi LED Ring for modern living

by crissxcross10. September 2016

The RGBW Module by Fibaro is able to actuate way more than just the LED Stripes from the home improvement center. This way your modern lamps become smart.

I really have not been blogging that much on siio lately. This was not because I was on vacation, but because I moved with bag and baggage and Smart Home. But 2x Daniel (Daniel König and Daniel Böber), as well as Gabriel, alias AlphaX2, Kevin, and Hamashi entertained you pretty well during that time.

My new home is an old mill with course of a stream and mill wheel, which after a structural restoration now provides modern apartments. This also means much space for my toys :-) I decided to show you a few things (scripts, tutorials and so on), which I implemented in my new castle, over the next days and weeks. Corresponding to that you can find all contributions to that topic under the tag “ChrisBautSchloss”. I already presented you the intelligent light control, today I am going to show you how to control a pendent light in color and brightness via a small modification via Z-Wave.

Wrong Imagination

There was one essential part in which the relocation confirmed me: “real” Smart Home is never going to happen “out-of-the-box”. I took all kinds of devices, sensors, and components from my old apartment, and left existing scripts on the Fibaro Home Center as well. Still, I cannot really “move” my Smart Home. For instance, even though I had a Fibaro Motion Sensor and a light in the hall before, I cannot really adopt it one to one. At this point I already need at least 2 Motion Sensors, since the hallway is pretty long. This does not only mean I have to adjust the LUA Script, but also the hardware configuration (how sensible the Motion Sensor has to react) and so on.

This is why I think it is not possible to sell a comprehensive Smart Home, which is already configured via “Starter package”, just like many people wish (and like the advertisement puts it into our mind).

Fibaro RGBW Module can do more than just controlling Stripes

But we already digressed enough (…) the Fibaro RGBW Module is supposed to be our topic. I already reported about how to connect it at some points before and this is not about the concrete wiring either, since you can look this up on here. I want to quickly show you on pictures, that even in modern lights, you can also accommodate the Fibaro RGBW Module in a completely invisible way. This is due to the fact that the Fibaro RGBW Module is not only able to control LED Stripes.

Some while before the relocation, I already fitted an RGBW Module into a Wofi LED Ring (desk lamp). In this case it is quite obvious, that the Fibaro RGBW can come into action, since an LED Stripe is used in the ring. There is enough space in the foot of the desk lamp to stow the Fibaro RGBW. Only the antenna should lead out of the casing of the Wofi Lamp, since the Z-Wave wireless range would otherwise be strongly attenuated by the metal casing.


Fibaro RGBW in a Pendent Light

I wanted a pendent light above the dining table in my new kitchen. I found an RGB pendent light on ebay, which could be varied by color via remote. Boring :-) So I directly ordered it for a pretty low price.

At first sight, it does not look like it is going to be easy to fit an RGBW Module in the pendent light. But there are 4 cables for each color (RGBW) per light (that makes 4x), as well as 1 cable per light for the mass, which all merge at different points. The Fibaro RGBW Module can drive 4 channels. R (red), G (green), B (blue), W (white). Handy, this way I am able to vary the RGB colors in the vitreous body and dim the warm-white light of the spot at the bottom of the pendent light via the W-channel.

The pendent light by Eglo had obstructed two transformer power adapters (from 230V to 12V). One of them served the RGB colors inside the vitreous body of the light, the other was for a warm-white spot at the bottom of the pendent light. Those were additionally interconnected with each other. I decided to remove both power adapters, and replaced them by an LED Transformer with 12V and 3A.

Luckily, I was able to express my wishes to my electrician. This way, he could lead 1x electricity (not switched) to the ceiling of the kitchen, as well as 2x potential-free switched cables, during the structural restoration. The handy thing about it is that the Fibaro RGBW provides four input channels.

At first, I thought about being able to vary every color channel separately, but this does not make sense. You do not do this in your everyday life. Therefore, I decided to “only” occupy two inputs. I now use the IN 4 (for white) to dim the spots with the warm-white light and at the other input, I am using the function to vary the color of the RGB lights in the vitreous body.

Next to setting up different cue states, the RGBW Module comes in very handy when giving optical feedbacks. This way, my lights blink blue, if a flood sensor has detected water or pulse yellow, if it is stormy outside – and one of the windows is still open. But more about this in one of my next tutorials.

too long to read

We already gave account that this module cannot only be used to control lights here and there. Thus, by way of example, we explained how a floor heating system can be controlled with the module. Due to its small frame size, the Fibaro RGBW is a mighty small and especially multifaceted tool. For what I think the best Fibaro has ever produced. Maybe the name was kind of an unfortunate choice?

(…) and where did you use the Fibaro RGBW Module?
