Welcome in the forum!

   

Smartsense adapts to changing environment as humidity, aging etc. So it might be that very slow changes are not seen as a keypress, especially when the button layout does not confirm with the recommended pictures.

When there is no bad handling CapSense in the software I would suggest to

   
        
  • read out the values SmartSense has found for your design and set those manually
  •    
   

or

   
        
  • design with CapSense Tuner and use those values (preferred)
  •
