So, I tried a few things at this point, without much success.
I have two gosund electrical (mini) plugs and one switch on a smartlife account.
The settings to link accounts only seem to link to tuya, so I created a tuya account and moved one of my smart plugs over to it for testing.
I then tried to link my tuya account and it goes through the authentication process, seems to succeed, but there's no notice of it succeeding on the sequematic side. Also, when I go to a sequence, it says I have no linked accounts.
If there's any information you need, don't hesitate to ask, and thanks for all of your effort.
