I have just got my board up and running and I am getting some weird results that is probably some user error.
I’m in Australia so its 240v. I have a 9vAC pack from https://www.altronics.com.au/p/m9233-powertran-9v-ac-1.33a-appliance-powerpack/
The voltage ref has been calibrated with a true RMS meter and is holding the correct voltage.
However I am just getting the wrong wattage results.
Here is my config
Here are my results

Is it user error? Does anyone see something obvious?
