Add Support for outlets from GreenSun

[Flausi]

Hello, I have an outlet from GreenSun (purchased through Amazon) which can be controlled and read via the app Vesync. Is it possible to control this socket also via pyvesync? Many thanks

You would need to send me packet captures. The process is involved but possible since vesync has used methods to prevent capturing packets. Happy to send you some details if you are interested.

Here are a few logs I took:
greensun-whogplug.txt

Looks like this is using the bypassV2 API that is already being used in some of the bulb handling code.

Hi, I've a Greensun power outlet, too:
Greensun Smart Socket, Model: P02, Firmware: 1.0.00
"type": "wifi-switch",
"connectionType": "wifi+BTOnboarding"
"deviceType": "WYZYOGMINIPLUG",
"configModule": "ZY_WFBO_OTL_WYZYOGMINIPLUG_UN"

No idea, if this might be helpful, but by chance I found what should be the firmware file:
http://testonline-fw.vesync.cn/ZY_WFBO_OTL_WYZYOGMINIPLUG_UN/v1.0.00/WYZYOGMINIPLUG_UN_ota_v1.0.00.rel.bin
It would be really great if you could add support for this model in PyVeSync!

If you need more capture data, I'm happy to provide it. Only need your instructions how to do it (and some time 😊).

Thanks, Martin

Hey Martin, you don’t have a copy of that file by any chance? I’m only getting a access denied error when trying to access it.

The link was wrong domain, sorry. Stupid copy&paste error … I've edited my message above and with http://testonline-fw.vesync.cn/ZY_WFBO_OTL_WYZYOGMINIPLUG_UN/v1.0.00/WYZYOGMINIPLUG_UN_ota_v1.0.00.rel.bin the download should work.

Just subing to this thread as I have the same issue and would love to see a solution. Also happy to help with any data, but you'll need to walk me through what you need...

Same for me :-) I'm an experienced Python developer, but it's been a while since I did anything with networks. I guess when you want packages to be captured that means using wireshark?

Edit: I think I figured it out in principle:

1. Create wlan access point via hostapd
2. Create a bridge via bridge-utils
3. Use wireshark

Let's see when I find the time to actually give it a shot xD

I can see to which domains it connects (or my smartphone):

analysis.vesync.com
long.vesync.com
operationapi.vesync.com
smartapi.vesync.com
store.vesync.com

But I don't see the specific requests as the calls are decrypted (although I'm in the middle, intercepting all traffic).

The only way to capture is to install the vesync APK on an Android Emulator (like Android Studio) using a generic android OS version. Then using frida as shown in Sections 4,5 in Ultimate Guide. After SSL pinning is disabled, capture packets with SSL proxy with charles or some other software that installs a root certificate.

Check out this for setting frida up. I never used genymotion, only Android Studio which requires a generic android OS to root the device.

btw I strongly suspect that these are devices similar to other smartplugs discussed in https://www.elektroda.pl/rtvforum/forum390.html. So if opening the device is an option, then you can flash OpenBeken and use the device via this tasmota-like interface.
