New to st. Can't seem to get my aeotec home energy meter 2nd Gen to work with St. Please help

Hooked it up to panel box. Then connected to smartthings hub. How in the world do I now get this thing to work.

If you successfully joined the HEM to SmartThings, then it should immediately start sending data and you should see it update in the mobile app.

Maybe I should disconext it and reconnect. Maybe that’s my problem.
