Ask a generic question about the usage of QLC+, not related to a particular operating system

Hello, everyone.I have a very complicated project with multiple shows scenes etc.Im using wired dmx lights and also some e1.31 lights.It all works very well .I am also using the web interface with no problem so far.But i want to control the lights wirelessly with a wifi button-controler or to make an automation when something opens, like a door that a show starts.How can i use a wifi device as an input trigger?If there is no commercially available product, can i make a device that connects on the wifi and triggers qlc ? Can you give me some guidance, please


Thank you

Welcome to the community,

Some devices in the wild allow you to use low-voltage inputs, giving you an Artnet signal.
These come with a cost, of course.
A device I already used: https://dmx4all.store/en/DMX4ALL-Produk ... ltiplexer/
If longer signal lines are in place: https://www.thewillows.nl/p/artnet-play ... 8-x16-x16/

Once your inputs are connected and the devices configured, the signals are present in an Artnet universe, which can be used as input for QLC+.
The wifi-part is not discussed here. Instead of Artnet, you should start using sACN (which can be network routed).

If you are a DIYer with some knowledge about electronics, a Raspberry solution is also possible. I have used Raspi's successfully in different setups. You will need some additional components to protect the (very) low-voltage inputs of the Raspi. I have fried some due to parasitic signal levels.

That's very interesting .Can you elaborate on the Raspberry? how did you configure it ? What software needs to run on it ?

The Pi runs QLC+, and the GPIOs are configured as inputs and used to trigger scenes. The outcome is sent by Artnet (sACL) to the main light board. Make sure that the GPIOs are isolated from the outside world. They function with 3.3V. Even if you feed them with 6V, you fry them. Quite a few parasitic signals are present in a venue, believe me.
The easiest way to get the Pi working is by making a small donation, and then you get access to the image you can burn on the SD-card.

I don't feel comfortable running my show from the Pi. Is there another way to run QLC and the show on a Windows PC while configuring the Pi to work as an input for QLC?

Hi GGGss,

if I did get it right, the idea was indeed to use the Pi only as converter from low voltage trigger to Artnet where you main station can receive input from Pi´s if needed.

Have fun

Yes, this is the only answer I can think of. ;-) You must be creative and start drawing schematics of how the signals will flow.
