Devialet Expert Controller and Web App

[andrewmg]

This will be old news to those following the "dual mono" forum, but my Expert Pro control script and mobile-friendly web app have been updated to work with single-chassis amps, too--as tested and debugged on one of my Expert 220 Pros that are usually paired as a 440.

Files and documentation, as well as a screenshot of the mobile app, are available here. And here's the thread in the dual-mono forum, which explains what this is all about:

Frustrated with the official Expert iPhone app's speed and wonky interface, I fired up Claude Code to design a replacement. First I (we?) put together a command-line script (in Python) to interact with the amp. And then I (we?) created a phone-focused web interface that's way faster than the official app. It works great. 

Anyway, I hope this is useful to those who are dissatisfied with or unable to use Devialet's Expert app. Please let me know if it works for you or if you encounter any bugs.

Hi Andrew,
I downloaded the zip file from github, but have no idea what to do next.
I have Devialet 220 Expert pro. Can you explain please what do I have to do with those files to have the app functional on my phone.

Assuming you have a Mac on the same network at the Devialet: Download all the files into a directory on your Mac, in the terminal.app enter the command "python3 -V", which should launch a prompt to install the developer tools if you don't already have those, then change to the directory with the files using the command "cd /directory/where/you/downloaded/the/files", and then try "python3 devialet_expert_control.py status", which should auto-discover the amp on your network and output its currrent status. If that works, you can use the instructions in the WEB_SERVER_SETUP.md file to get the web app running. If you can get the server running manually and confirm that it works on your phone, then go ahead and follow the instructions to run the server at startup. After that, it's permanently installed, and there's nothing else to do. 

This should also work on a Windows or Linux computer with Python 3 and the appropriate libraries and permissions, but I haven't tested it.
