Hello everyone,

My setup (France, single-phase):

SolarFlow 2400 AC+ (2.4 kWh built-in battery)
SmartMeter 1CT-S, clamp on the main house supply
An existing Sunology Play panel (about 400 W, built-in micro-inverter), plugged into a socket on a circuit that also feeds other loads (TV, computer…)
Peak / off-peak tariff (HP/HC)

The panel cannot be plugged into the SolarFlow's off-grid AC socket.

As a result, HEMS has no knowledge of the panel's production, it only sees the net value at the meter. ZENKI cannot forecast the next day's solar production to decide whether to charge from the grid during off-peak hours or leave room in the battery for solar.

My questions:

Is there an official way to register, in HEMS, the production of an existing micro-inverter that is not connected to the SolarFlow?
If so, with which hardware:
- a second meter (e.g. a second 1CT-S) on a dedicated circuit for the panel?
- a multi-clamp meter (Smart Meter 3CT or Shelly Pro 3EM) replacing the 1CT-S, with one clamp on the main supply and one on the panel's circuit? Can HEMS then assign a clamp to the "PV" role in single-phase?
- a smart plug (Zendure Smart Plug or Shelly Plug S) between the panel and the wall socket? Can it be declared as a production source rather than only as a load?
Without a production measurement, can ZENKI still build a solar forecast, for example by entering the existing installation's power and orientation?

Does anyone have a similar setup working? Thanks in advance for your feedback.
