Thank you! And in the handful of minutes between my post and your reply, I did manage to stumble across those settings. After a “re-connection” of the Alexa third-party service in the Vesync app, VOILA!
Now the virtual switch (am I using that terminology right?) in SmartThings properly controls the first of the two “old” wifi outlets I have.
Trouble is, I can’t get the same procedure to work for the second “old” one.
And I do still have a new / “fresh” one that I haven’t set up at all yet…
Anything I might be missing in getting the virtual switch in SmartThings to function the second outlet?
