Edifier MS50A

I own a few of these devices and I am trying to figure out how to use the LinkPlay API with them.
However, I am not sure it's accessible at all.

1. Port 80 is not open for HTTP traffic.
2. It definitely listens for TLS traffic on port 443 but it seems to want a certificate sent in. As a hail mary, I tried using the LinkPlay-signed cert from linkplay.com, but no dice.
3. I have sniffed traffic on Android and Both Edifier Home and WiiM Home (that also works with these) use UPnP/DLNA (HTTP, port 59152) and I can successfully craft such requests. Well, more accurately, the WiiM Home app first tries the LinkPlay API but those requests also fail and it seems to fall back to UPnP/DLNA.

Firmware version: 4.6.430230, build date 2022-09-23

Has anyone looked at this before and have any ideas?

I also have a pair of Edifier S1000W incoming and I'll see how that works, but I'm guessing it'll be the exact same.

@jstaro seeing the exact same behaviour… Does your S1000W also requiring a SSL-client-cert to connect?

It also requires HTTPS connection on my Yamaha YAS-209. I managed to access the API. I wrote a post (In Chinese, but should be readable after translation) about how I found certs and APIs.
