I do not have an IoTaWatt yet, but I plan to get one when they’re back in stock. That said, I had a question:
In the “CT Basics” documentation (CT Basics — IoTaWatt 02_03_20 documentation), at the very bottom, it says “Two individual CTs can also be combined with a common headphone splitter and fed into a single IotaWatt input. When combining this way, both CTs must be the same model with an individual capacity sufficient to measure the combined capacity of the two circuit breakers.”
Would that also work with the mains split phase? I have a 200A split phase 120/240v panel and it surely would be nice to be able to monitor almost all circuits, I attached some pictures below for reference.
