How to make settings persistent for multiple users (multiple users share the same settings)


I think I want somehow to use dash for “off-label use”. I would like to have that all users see exactly the same app: If user 1 switches on something, it should be switched on for user2, user3, etc. Also if user 2 selects from a dropdown, the same entity should be selected at the other users.

The reason behind this is, that I want to control a RGB LED stripe and sound over a web page from different smartphones at the same time.

Is there any solution to this? I thought I could write all variables to files and read from there?

If someone can recommend a better solution than dash, I would be happy. I have chosen dash, because I already made some data visualization with dash and python.

Thanks in advance!
