Alternate Reboot function

[adn77]

I have a few GGMM E5 speakers (Project GGMM_E5A). For those the reboot call just returns unknown command (via HTTP and HTTPS)

Recently I found the Restart option to be implemented in the latest WiiM Home Android APK which actually reboots my speakers.

I tried decompiling the APK as well as MitM-Proxying and Wiresharking the calls from the app.
Well, I haven't found out how the reboot is actually triggered 🥹

Please let me know if you happen to know of any other way to reboot a LinkPlay speaker.

PS: if you're interested in more undokumented API endpoints (probably for newer devices) let me know ;)
