I don’t understand where you are getting these PF from. This implies they are from IoTaWatt, yet IoTaWatt doesn’t output PF to 6 decimal places. So there are some details missing. Could you post some pictures that illustrate how you are setting up this experiment?
Where is the CT located and does it go back to zero when you remove the bulb or kettle?
Can you post the config.txt file?
Do you have more than 1 CT and if so, can you clamp several of them to the same cable and show the status display with all of them reading the kettle load?
