I'm about to implement some power monitoring for our US split phase setup. I'm starting out just monitoring a 240V generator breaker that is setup via an interlock in our electrical box and some circuits associated with our HVAC. I'm under the impression that in order to accurately monitor L1 and L2 coming from the generator, I'm best to implement a second voltage reference. My interest in the generator in particular is that unlike power from the mains, the loads on L1 and L2 can vary depending on what is being powered in the house and each leg has a maximum power output. It's also my understanding that the best practice is to keep L1 and L2 from the generator as balanced as possible.
In my initial setup, I'd also like to record the power used by the heat pumps and their associated air handlers (both 240V) as well as the circulators and boiler (both 120V). I believe if you reverse the CTs on L2 of the 240V circuits you can combine 2 CTs going into a single port on the ESP32 Energy Monitor board. Is this correct?
The diagram below shows how I'm planning on hooking things up. Any feedback would be appreciated. In the future I'll add more circuits including our solar (which is already recorded via Enphase), the whole house and EV charging.
