Did you know you can 'convert' real simple an Enhanced design ("K" in device number) into a Basic design ("T" in device number)?
And vice versa ..
Just load the .hmi file into the Nextion Editor, choose the device which you have ( Menu item Device ID) and save the file... It is converted to your device type
Note: this is working for Nextion displays with the same size! It is not converting between sizes (no re-scaling)
