Advanced Modbus registers

[Jo-Kaan]

Hello,
I have a request or suggestion about expanding the ISG integration. Some time ago I modified the ISG so that I can read out additional Modbus registers that are available according to the Stiebel-Eltron documentation. This means that further parameters of my heat pump LWZ/THZ 504 are available to me for evaluation. So far I have read out the ISG using my own Modbus queries in Home Assistant. If I switch to the integration you provided, I can no longer query these values.
Is it possible to include the complete register set of the ISG/heat pump in the integration?
This would require the following register range: 0-85, 1000-1029, 2000-2035, 3000-3036, 4000-4002 and 5000-5003.

For the output of the daily consumption and performance values, an output with a decimal place for the Wh would also be very nice (e.g. 2.346 kWh).

Best regards
Jo Kaan

I have the WPL-25 and I was wondering where the "Inverter Power" was, so that I can track when the energy is used through the day, rather than look at Heat or Water energy produced, so I am keen to see the full set of my HPs ISG data presented in the integration

With the ISG Version 5.12.2.3 the ISG has the Power Consumption Values integrated. Also the Power Consumption of the Heatpump

These registers are also availiable via Modbus (WPM/LWZ).

 - name: ISG_CURRENT_POWER_CONSUMPTION_HP1
    unique_id: ISG_CURRENT_POWER_CONSUMPTION_HP1
    address: 3679
    slave: 1
    scale: 100
    input_type: input
    unit_of_measurement: W

The values are different because i was too slow with the screenshots :-(

for the secondarys (WPM only):
3680 HP2
3681 HP3
3682 HP4
3683 HP5
3684 HP6

@mbeckerkassel I have updated to v12.2.3 yesterday on a WPM 3i. On my ISG, the register above is not available. The highest register in the 3xxx range I can read is 3522.
Do you have any proposal on how I can access the register?

[mbeckerkassel]

Sorry. I should have more specific. The Objects are valid for the WPM System and the LWZ. Not the WPM 3i. Perhaps you want to contact me directly so we can figure out what we can do. [email protected]
