The Nextion display needs the content defined in the file PowerMeter.HMI. You can either upload it with the Nextion editor via a serial link to the display or you can copy the TFT file to an SD card and put this into the socket on the Nextion display.

 I assume the simplest way is to copy the TFT file on an SD card. The TFT file can be found if you open the HMI file in the Nexion editor and then select "File - Open build folder" from the menu bar.
