Does QLC+ have an API so that higher functions can be implemented?

I would like to try extending QLC+ with some more extensive cue list functions for working with a stage show or play. Is there an API? Can the web interface be used this way? Is there any documentation for this? Thanks

What is your idea?

Web API can be reached from the QLC+ website main page: https://www.qlcplus.org/Test_Web_API.html

I don't have a specific idea. I learned lighting on ETC systems and tend to think in terms of their style of cue lists. I do like QLC+ for the low-level handling of lighting equipment, but I have not figured out any satisfying way to program a full-size show. I thought I might try some ideas and see what could be done. What I ultimately want is an ETC style "GO" button so that a show can be run easily by a helper that doesn't know much but can read a script.

I'm having trouble with the Web API. I'm running the qlcplus service on a Pi4, and point the Web API to the proper IP address and port. Regardless of what I try, I just get "Not Connected" next to the connect button. I also tried running the full QLC program with the same results.

Interestingly, when I load the project with the buttons, I do get my project to populate on the right and the buttons actually work. However, I can't use any of the API functions on the left.

I don't have any port restrictions that should be causing this.

Do I need to enable access somewhere?

I'm running QLC+ 4.12.2 from the DEB file on a Raspbian Pi4.

I managed to get it working. I don't know why I didn't think to try a different browser... I guess I was troubleshooting too long to think straight.

For what it's worth, I got it working on Chromium on the same Pi as QLC+ is installed on.

Hi

Have you been able to get access to the QLCplus web service for a different machine?

I've flashed the PI image and it seem to boot up okay, with QLC showing as an active service in TOP, using about 4.1% of memory.

Is there a configuration file that I need to edit to allow web access from my LAN?

Yes, I usually log in from the Pi itself since it's sitting on my desk, but you should be able to log in from a different computer on your network.

You might find it useful to assign a custom hostname using the

raspi-config
command. Mine is icarus.local, so I can reach the web console at
