I have ordered and IoTaWatt and would just like to measure currents for individual circuits in a house that has a three phase supply. That is there are different circuits that I want to monitor on different phases.
I have seen a post that explains how I can provide 3 voltage inputs (each phase) and then measure watts for each of the circuits however it will be difficult for me to get access to a voltage input for each phase (or any phase at all).
The reduced accuracy of not using voltage is OK as I am just doing an approximate survey of a house electricity use to see where and when the big power usage is happening so I can target appliances for more detailed analysis.
I am thinking I need to modify the code to just insert a fixed 240V constant voltage but it may be more complicated than I think with the zero crossing timing code and the three phases.
Any ideas or comments that will guide me would be appreciated.
