Ok, that tells me that your hub thinks it sees the device. You should have seen the “checking…” message first, which led up to this message. That’s what typically happens on a Replace when it’s not really dead.
No worries at all. The IDE is a developer site where you can get a lot more information about your hub and devices, use custom code, and do other things you can’t do through the mobile app. You should be able to go to http://ide.smartthings.com to check it out. I believe you just need your Samsung account info to log on and see what’s there.
Saying all that, it doesn’t look like to me that you’re using the right device handler for the device, and your comment about not knowing what the IDE is supports that. You should be seeing power and energy values in that screenshot from your first post. Look at this post here for examples:
That post also has a lot of helpful information, as does @TheSmartestHouse’s site for your device:
Both of those sites have the device type handler you’ll need to get this device working right. On the SmartestHouse’s site, scroll down to “Works With” for more info on using this device with SmartThings. I highly recommend using this device type handler (DTH) code. The wiki also does a good job explaining how to use custom code.
