The Tapo app is missing the ability to add custom icons or photos to identify each device.    The Kasa app does a great job with that but the Tapo app is very subpar.    
 

At the minimum add more icons beyond the 10-15 that are available today.  At least add that.     But the real solution is to copy exactly the behavior found in the Kasa app which has excellent UI.  
 

There are threads out there of this very same issue since 2023.   Adding icons should be a no brainer that needs to be done soon in the app.   I understand that adding camera or custom images is more difficult but come on!!!!    Do the minimum and add more icons.
