Modbus Registers for KH10 (EPS & CT2)

Hi,

I am setting up a data analysis SQL to basically get all the data relating to generation and usage from home assistant (connected to KH10 via Modbus using Nathan Marlor addon ).

This is working for most variables but I am having trouble locating two bits of information that I ideally need
  • Energy Used from EPS Port (kWh) - Like to be able to see in a blackout for example how much power was utilised
  • AC Coupled Solar Generation (kWh) - I can see my daily generation from my DC coupled solar but not the AC coupled which is sensed via CT2 (to be clear it is shown in the FoxCloud app. Alternatively I would settle for a combined total of the DC and AC coupled
When I search around online so I can look to go the manual route I seem to find a whole bunch of just random registers. Each I have tried just displays 0, a number that is clearly something else, or not available (and stays that way). Any pointers would be greatly appreciated and there is then the issue that it appears some register mapping has changed over time with firmware updates (Master 1.60, Slave 1.02, Manager 1.58).
