Operation & light scenes

Updated 9 October 2026Lighty

You operate your lights however suits you at the moment: with the wall push button, on the SmartKnob or in the dashboard. All three ways are equal and always in sync. No matter where you change something, everything shows the same state.

With the wall push button

The wall push button follows a simple logic:

  • Short press: light on and off
  • Hold: dim smoothly brighter and darker. The next time you hold, it dims in the other direction.
  • Hold while the light is off: the light starts very dim in the colour you last chose and gets brighter.
  • Double tap: switches all lights in the vehicle on or off. This is your good night switch without any extra wiring. Because it switches several modules at the same time, it needs the SmartKnob.

This is how the push buttons work once you have set them up with the SmartKnob. How they behave without a SmartKnob is explained in "Lighty without a SmartKnob".

Gentle instead of abrupt

Lighty never switches abruptly. When you switch on, the light fades up in about one second, and when you switch off, it fades out in just under one and a half seconds. Every change in brightness runs just as gently. Only when a protection function trips does the light go off immediately.

On the SmartKnob and in the dashboard

On the SmartKnob you select the light and turn to dim. In the dashboard, every device on the vehicle Wi-Fi becomes a lighting control, without any app, simply in the browser.

Light scenes

You save your favourite combinations of brightness and colour as a scene and call them up again with your smartphone or via the SmartKnob, for example "Cooking", "Evening" or "Night light".

What can I control with Lighty?

Lighty controls all the lighting in your camper over 5 independent channels. Everything is possible, from a single white strip to full RGBWW lighting with colour plus warm and cool white. Or you connect up to five individual lights, such as kitchen, bathroom, bed left, bed right and outdoor light, each on its own. You set colour, colour temperature, brightness and entire light scenes just as you like.

Does Lighty work on 12V and 24V?

Yes, both without any changes. Lighty works in the range from 9 to 36V, so it is just as much at home in a 12V panel van as in a 24V motorhome.

Do I need a SmartKnob for Lighty to work?

Not necessarily. From firmware 0.4.7, a new Lighty responds to its push buttons straight away, without any setup. With Lighty Extension, each of the five push buttons switches its own channel. A short press switches, press and hold dims. With just one push button and no Lighty Extension, you switch channel 2. Even if your SmartKnob ever fails, your push buttons keep switching and dimming. The SmartKnob adds colours, white light (warm white and cool white as one light), scenes, the dashboard, automations, the wireless push buttons and the double tap for all lights.

How is Lighty connected, and what is in the box?

Connection is deliberately kept simple: power and light channels go into high-quality Phoenix lever terminals, almost tool-free, safe and reusable. You wire the push button to the supplied pluggable spring terminal connector and then simply plug it in. In the box you will find Lighty, four mounting screws and the pluggable spring terminal connector for the push button.

Which LED strips work with Lighty?

Lighty controls single-colour and multi-colour LED strips with shared colour channels, meaning normal single-colour strips as well as RGB, RGBW and RGBWW strips. Addressable pixel strips (such as WS2812), where every LED is controlled individually, are deliberately not supported. Lighty is not designed for them.

How many metres of LED strip can I connect?

What counts is not the length but the current: Lighty handles 20A in total. For example, a COB strip with 14W per metre draws about 1.2A per metre at 12V. Two strips of 3m each come to roughly 7A and fit easily. Several strips may also share one channel.
