I looked up this model but just to be sure, this is a Z-Wave device, correct?
If yes, you have 2 options. You can exclude (not delete) and re-add the switch and see if it adds correctly or you can change the device type in the IDE.
Option 1 - Perform an z-wave exclusion:
In the app go to the Devices tab
Find your hub device and open it
Wait until the 3 dots appear in the top right
Click the dots
Select Z-Wave utilities
Select Z-Wave exclusion
Follow the device instructions to exclude
Then you can re-add your device like you did before.
Option 2 - Change device type in IDE
On a web browser go to
Log in with your Samsung account
You should see a screen like this
Click on the My Devices
tab at the top
Find your fan that displays properly and look at the Type
Return to the previous screen and find the fan that isn’t correct, click on it
Look at the type. If it is different than the first one
Scroll down to the bottom and click Edit
Under Type, click on the drop down and find the name in the list that matches the other
Scroll to the bottom of the page and click Update.
You should then be able to go back into the app and see the change.
