Without any public API available I found an awesome post by Benjamin Hanke documenting his journey on reverse engineering the basic controls for controlling this device. It would be possible to accomplish this by enabling tcpdump on any selected device and downloading the file using task manager on RMS and issuing uci commands.I recently purchased some Libratone Zipp Mini speakers that were on offer and wanted a way to control these through Home Assistant. As an example, I'm leaving a brief reply regarding the configuration of this case. Please note that tcpdump can fill up router RAM very quickly if there is a lot of traffic and it may slow down the device to a crawl if left unchecked - make sure that the tcpdump runs only for as long as it needs to, otherwise disable the service and remove the file (or reboot the router) after downloading it on RMS.

When everything is done, save the task group. Note: naturally, due to how many settings and variables are being used here, some of them can and should be modified according to circumstances.
