I just got my IoTaWatt device and have connected it to some SCT013-000.
I have also installed emoncms and linked the IoTaWatt with this.
The problem I have is that on the status page of the IoTaWatt it show too low Wattage, I put on 2200W load and it only shows 1100W.
I use an oven and confirms the load with an old watt-meter I have in my house.
I have calibrated the AC-AC adapter so it shows the correct value.
I have tried to edit the config.txt and tables.txt “cal” value, but nothing makes a difference. (After a restart of the IoTaWatt)
I have seen that I can multiply the input from the IoTaWatt in emoncms to get a close to accurate measurement.
But what is the recommended way to do this?
