I bought one Samung smart plug last week and added it in with no problems. Just bought another 3 and having problems adding them. If I plug it in and scan, the app finds nothing.
If I scan the QR code or add it through the UI by choosing Smartthings and the outlet then it comes up with the screen as per the attached. I tap the blank blue button and it asks for a room. Then says “Processing” for a few seconds and goes back to the add device screen. If I then go back to the dashboard, the device isn’t there. This is the same on 3 brand new plugs.
