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 ;)

@adn77 I get the same unknown command for my Edifier S1000W speakers when I try to reboot them. Sometimes they do need a reboot to fix wifi issues, so it would be awesome if a method was discovered.

Based on your comment, I downloaded the WiiM Home app for iOS and tested the reboot function. It works! Now, trying to figure out how to reverse engineer or proxy this traffic. Very annoying that this isn't documented anywhere...

Try this command:

StartRebootTime:1

@silamon any chance that additional StartRebootTime:1 command could be tried as a fallback if an error response is returned by the device from the standard reboot command? This would allow the "Restart" button in HomeAssistant to work with this speaker

instead of

[adn77]

Try this command:

StartRebootTime:1

I spent lots of hours trying to find this command! Thank you so much @luckman212 that works for my speakers!
