Hi @J-N-K, I selected ‘3…Discover direct, Alexa and openHAB skill devices’ under the Amazon Account thing. I then hit ‘save’ and go to the Thing page, ‘add’, ‘discover devices’ and all of my devices from the 'smart life app aren’t appearing.
One thing that I came across was this article about Tuya devices. MIne aren’t Tuya but perhaps they use the same protocol? This article is for OH2, not 3 so I didn’t want to go down an unnecessary rabbit hole.
