Delete removed devices from 'Things' menu

I have quite a few devices (two Smartthings locations) that were replaced with new devices. They still appear in the Things list. How do I remove them? Thank you

You can proceed through the authorization flow again from your SharpTools User Page → Manage Connections for each location to perform a full sync.

I have no issues running the Manage Connections process. However, once I’ve added a device, how do I delete it from the “Things list”? Example: I purchased a Temp/Humidity sensor. Added it to Smartthings. Ran the Manage Connections. It’s in the Things list. However it fails the next day. I remove it from Smartthings. It still is displayed in the Things list. Over the years I’ve replaced (a lot) devices, but they remain in the Things list. That has become very cumbersome to deal with. Create a ‘name’ that is different from the previous device, performing the same function, so that I can tell them apart.

You need to remove the devices from SmartThings first.

Then when you go through the manage connections authorization process, it will sync over the fresh list of device devices as reported by SmartThings and will remove any devices which no longer exist in the source smart hub.
