Phases?

[WooeBetidee]

I got solar panels and sigen inverter + battery installed last summer, and installed this integration shortly after.
I noticed that there were no sensors for L1, L2 or L3, so I figured that that info was probably simply not provided by the inverter... shrugs
Then this morning I saw in the app that there is in fact info for them, so I googled around a bit and found some pdf about 'Sigenergy Modbus Protocol', which seems to list addresses for things like 'Plant phase A reactive power', '[Grid sensor] Phase B active power', 'Phase C voltage' etc.
Would it be possible to get sensors for some of that?
I have occassional issues with imbalanced load and am trying to monitor how the power flows throughout the house. The reader at incomming power splits it into phases, but the moment the solar produces or the battery kicks in everything gets jumbled.

If there already is support for it and I have somehow messed up how to get it, then that'd obviously work too :p

There is a sensor in the integration that shows the overall house power demand (sigen_plant_consumed_power). However I also wanted to know how this consumed power was split across the individual phases and could not find any sensor for this. So I added the following to the sensor section of my templates.yaml file.

    - name: "My House Power Demand-Phase A"
      unique_id: my_house_power_demand_phase_a
      unit_of_measurement: "kW"
      state: "{{ ((states('sensor.sigen_plant_phase_a_active_power_2') | float(0)) + (states('sensor.sigen_plant_grid_phase_a_active_power') | float(0))) | round(3) }}"
      
    - name: "My House Power Demand-Phase B"
      unique_id: my_house_power_demand_phase_b
      unit_of_measurement: "kW"
      state: "{{ ((states('sensor.sigen_plant_phase_b_active_power_2') | float(0)) + (states('sensor.sigen_plant_grid_phase_b_active_power') | float(0))) | round(3) }}"
     
    - name: "My House Power Demand-Phase C"
      unique_id: my_house_power_demand_phase_c
      unit_of_measurement: "kW"
      state: "{{ ((states('sensor.sigen_plant_phase_c_active_power_2') | float(0)) + (states('sensor.sigen_plant_grid_phase_c_active_power') | float(0))) | round(3) }}"

If I've understood your need correctly, perhaps this will help.

EDIT:
Just thought I should mention that although these figures when added up do equal the total value provided by sigen_plant_consumed_power, they do not match that shown as house consumption in the Sigen App. This is because the app seems to "hide" some of the internal system losses in the figure it provides. The real house consumption value is usually a little lower than that shown in the app. They also make a similar small adjustments to the PV Power and Battery Power values in the app, presumably for the same reason.

I guess that's where my issue lies, I have no sensor.sigen_plant_phase_a_active_power or phase_b or phase_c...
I've got sensor.sigen_plant_consumed_power, sensor.sigen_plant_plant_active_power etc, but not a single sensor relating to phases.

Edit: Nevermind, I found it. I know I looked through the disabled entities back in the summer, but I guess I was blind, or it was just too many there.
New definition of sensory overload.

Ah yes, I forgot that these entities (and hundreds of others) are disabled by default in the integration. It was quite a while back when I went through and enabled all those that could be useful. Anyway, glad you've got it sorted now. Hope you manage to track down your load imbalance.
