Monoprice Monolith HTP-1 IP control

Has anyone figured out the HTTP control for the Monoprice Monolith HTP-1 processor? The manual has IR codes but almost no BTS for the web server app that seems to be pretty in-depth. I guess I would only need power on/off, volume up/down, volume level, and current audio modes to start off but adding any other of the features would also be cool.

How hard would it be to reverse engineer the commands from the web server?

The manual for the HTP-1 is here:

The native HTP-1 app uses Web Sockets to control it. Messages are super easy to see with any browser developer tools.
