I bought these a few years ago. Their platform got taken down. And they are supposed to work with smartthings. I tried resetting it and everything… No clue
The model number matters. The Iris zigbee plugs work fine with SmartThings. The Iris WiFi plugs unfortunately never did except through the Iris IFTTT channel, and that was discontinued last year.
Oh only the zigbee ones makes sense
Your subject says “wifi plug”.
