Is there any interest in a Stiebel Eltron climate platform?

As you know, I have copied your Stomverbrauch / Wärmemenge / Verhältnis for my dashboard. However, as the new year started, I’d like to have “this year”-values.

To create this, I need entities that reset the values of produced_heating_total and consumed_heating_total on every January 1st. Do you have any idea how I can do that? Of course I could do it manually (create an entity that subtracts the value from January 1st 2024 of the total value from today’s total value) - but then I’d have to adjust it every year manually. Do you know a way so this gets done automatically?

Thank you in advance!

That sounds like a job for a utility-meter with yearly cycle.

Hey umrahth, you can do it easier by setting the SG Ready Input 1 to On and Off. You can set the Temperature in the isg web for On …

After installing everything necessary for cooling and enabling it, I noticed that anything cooling related (except for the “iscooling” entity) is not functional.

I can neither set the cooling temperature nor can I change the mode or anything.

Anyone with similar issues?

I’ve just received an answer from the Stiebel-Eltron support.
The cooling-related entities are not exposed via modbus for LWZ-devices.

Seems, the only way is to hack the settings on the card to get access to the data. :frowning:

Hey Ingo or everyone :wink:

First off newbie HA - thought I quick install Stiebel ISG integratio and off we go - but NOT.

So I like to thank everyone in this thread for being so helpfull !!

BUT :wink: Anyone accomplished to read the QUELLENTEMPERATUR

When I follow the logique -1 and I add 535 with following code

      - name:                'Brontemperatuur'
        unique_id:          wp_sg_brontemperatuur
        slave:                 1
        address:             534 #535 - 1
        input_type:         input
        unit_of_measurement: °C
        device_class: temperature
        scale: 0.1
        precision: 1  

I get

When it has to be I think

Totally offtopic - but has anyone connected a Fronius GEN24 to Stiebel WP for SG Ready?

Many thanks for answering

32678 is the value you get, when the call was not succesful.

I think you may have the wrong adress.

According to https://www.stiebel-eltron.de/toolbox/content/docs/anleitungen/installation/ISG_Modbus/321798-44755-9770_ISG%20Modbus_de_en_fr_it_nl_cs_sk_pl_hu.pdf it should be 535 (536-1) or 536 (537-1). See:

Hey everyone,

I own a CS8 Premium and have this integration installed. I can read all values ​​but cannot write values. Any ideas?

Nice new information about 32678 value.

I was wrong about 534 but I entered 535 & 536 and still no luck.

What can we conclude

  • Quellentemperature is unreadable ?
  • ISG ver 12.2.2 documentation is not updated ?

Many thanks

Hello Ingo, first of all thank you for the Stiebel Eltron integration via HACS. I don’t understand why I need the modbus.yaml file. The integration already delivers all elements automatically.

I would be very grateful for your help.

Thank you very much.

Yes, over here it’s exactly the same. All the entities for cooling are disabled. I don’t care, because I can’t use my heatpump for cooling (because I use radiators) and we have AC’s installed in our house.

Hi. I am very impressed with the amount of work that has gone into mastering STIEBEL ELTRON heat pumps.
I have a question, has anyone tried to control an additional PV-E-E heater via modbus?
