Hello @PyGuy,

You may be able to use something like this:

New websocket component: DashSocketIO

Hello everyone I have just created a new dash component dash-socketio, to go hand-in-hand with flask-socketio. It allows to do some pretty cool things with Dash like notifying the user of progress while a callback is running, or streaming outputs while a callback is still running. See below a GIF of usage.py in the repo. This is a toy example with the above 2 usecases implemented. [dash-socketio-usage] Hopefully this can be useful to some of the community!

Basically, on a db you keep track of the last callback executed by the user, could listen on the server using the flask.before_request method to do that.

Then have a function that checks logged in users and their last activity time, if it is outside of the time frame, then you send a message and when the message is received it causes them to log out.

This might be easier to perform on something like a quartz server too, but a little more tricky to have the socket have the user info, since that info is in a different server.
