Luckily it’s a simple change.
Thank you very much for that, Hannes!
I have to admitt that I had little hope to get an answer and tried it on my own after my last post here.
Maybe my solution is from intrest for someone else or maybe even for you as I additionally decode the status signal of the heatpump (LWZ404 BETRIEBSSTATUS). I did not integrate all signals for now, but with your work that is a quick deal now. Your solution with the “scale” command is certainly better than the postprocessing via sensor template.

Your’re welcome 
And thank you for decoding the BETRIEBSSTATUS - will definitely use that one!

Greetings from Switzerland!
We do run a Stiebel WPL20AC here and i got it “somehow” to work by using the ISG modbus guide and check each number by comparing it with the ISG homepage.

But as the config file is now growing i wanted to “outsource” stuff with the include commands.
And here my struggle begins.
I could manage the modbus.yaml

# E3DC Power Reactor

configuration file → modbus: !include modbus.yaml
BUT i am failing constantly with the sensors stuff…
created a sensors.yaml
configuration file → sensor: !include sensors.yaml
File looks like this:
#
- platform: modbus

So two things here:
- i used two modbus hubs (hub: isg and later e3dc)
- I fail with the formatting
Would you guys please enlighten me on what i am doing/formatting wrong here?
Details:
Asustor NAS, Docker HA Version core-2021.10.7
Any tip is much appreaciated!
thank you all!

ok i think i found a solution to split the stuff.
# Include sensors (all in a seperate *.yaml)
sensor: !include_dir_merge_list sensor/
# Include modbus (all in a seperate *.yaml)
modbus: !include_dir_merge_list modbus/
created directories modbus and sensor.
in there seperated all the sensors and modbus configurations in to an extra files and merge them while load.
/sensor
— systemmonitor.yaml
— asustor.yaml
/modbus
– isg.yaml
– e3dc.yaml
Used ssh to create the files and folders to they kept the owner and permissions.
AND finally… it seems that with the update the modbus configuration has changed.
- platform modbus does not seem to work anymore.
So i had to put the modbus and sensor config into a file and load it with merge.
modbus file → isg.yaml

Evening Gentlemen,
I started digging through the modbus of the ISG again but i am unable to find “the rest” of the values.
Please see embedded picture. I can find the the number before the comma appears but i am not able to find the values behind. Picture is in german but i think you can get what i mean.
Excample: heat production of the day Modbus 3500 or 3522 shows 38 kWh. But 3499 or 3521 does not exist and so i cannot find the missing 0.939 kWh.
Same for some other sensor values. I can find the kWh but not the 0.xxxx values behind.
Did anyone encounter the same and could solve it? I checked most of the modbus IDs but these values just did not appear.
On the picture you also find some values made from MWh and kWH: For them i used a template sensor which adds them together.
# Heating Total calculation
# ISG Consumption Heat Total Part1 Energy + ISG Consumption Heat Total Part2 Energy
# These two sensors are the total used energy for heating electricity consumption

Just make sure you set the MwH to scale 1000 so you get kWh. Then add them together.
And one more thing.
Could you help me to get a write register? i did find the room eco and comfort temperatures and they appear to be writeable.
Comfort
- name: ISG Comfort Room Temperature
slave: 1
address: 1504
input_type: holding
scale: 0.1
precision: 1
unit_of_measurement: °C
device_class: temperature
Eco
- name: ISG Eco Room Temperature
slave: 1
address: 1505
input_type: holding
scale: 0.1
precision: 1
unit_of_measurement: °C

Would be cool to have a dashboard card to be able to change it.
thank you very much!

Evening,
how did you implement the “Betriebsstatus” into the Lovelace?
Just an entity set?
thanks
armin
I wonder what all the steps are to get this working. We have a similar system, the WPL15AC+ISG-web
Hi Dennis,
to monitor your 15AC you would need to run the modbus integration.
With this and the registers you then get loads of details which you can later process in Home Assistant.
Install Modbus Integration
Use the modbus configuration on your configuration.yaml or an extra file.
Reload and you get sensors with the details. Use entiies or sensors in lovelace and you get them on your dashboard.
Its was a bit tricky for me at the beginning and a lot of trial and error. But i could manage to get pretty close to want i expected. see screenshot.
Our WPL20 uses the same registers you could start using the one i dropped here.
If you need more help let me know.
cheers A
PS: it is worth the work. The ISG web interface is “ugly as hell”
About the set komfort and room temperature:
Create 2 helpers (input numbers) Eco and Comfort
Then 2 automations. One for set another one for sync.
Modbus Holdings are:
# Temperatur Sets Room Comfort and Eco -> these can be written as well.
# Comfort
- name: ISG Comfort Room Temperature
slave: 1
address: 1504
input_type: holding
scale: 0.1
precision: 2
unit_of_measurement: °C
device_class: temperature
# Eco
- name: ISG Eco Room Temperature
slave: 1
address: 1505
input_type: holding
scale: 0.1
precision: 2
unit_of_measurement: °C
device_class: temperature
Set Temp automation:
alias: ISG Temperature Comfort Set
trigger:
- platform: state
entity_id: input_number.isg_comfort_temperature
action:
- service: modbus.write_register
data_template:
hub: isg
unit: 1
address: 1504
value: '{{ states.input_number.isg_comfort_temperature.state | float * 10 }}'
Sync Temp automation
alias: ISG Temperature Comfort Sync
trigger:
- platform: time_pattern
seconds: '59'
action:
- service: input_number.set_value
data_template:
entity_id: input_number.isg_comfort_temperature
value: '{{ states.input_number.isg_comfort_temperature.state | float / 10 }}'
Use Number Card from HACS and use them on the dashboard.
type: custom:numberbox-card
border: true
entity: input_number.isg_comfort_temperature
name: Temperatur Komfort
I guess there might be better ways but this one i found and it works fine.
Hope this helps.
cheers A
Wow, I love your Lovelace interface. got it partial working, the readout of power consumption, running hours is showing up.
some modbus adresses are not matching up with the former code you posted
Is it possible that you share the modbus ISG.yaml and Lovelace cards again.
Hi Denis,
Modbus ISG
This is was i used. Focus on WPM system colum.
I went through most of them one by one. The issue is the offset. You have to use -1 or sometimes -2 on the register numbers. What i did i created the modbus address in a range.
eg:
1500 i created 3 entries 1498, 1499, 1500 and compared the results against the ISG webpage.
with that i could get most of the details i wanted.
Its a shame that they use so many different variantions for each product as your 15 and our 20 are the same …
About my config. Here i created a seperate modbus folder and moved all the configs out of the master configuration file. On the config file i used the pointer to integrate the directory.
my structure looks as follow
config folder
→ configuration,yaml
→ modebus folder
------------> isg.yaml
→ sensor folder
------------> isg.yaml
Here is the code for configuration.yaml
# Include modbus (all in a seperate *.yaml)
modbus: !include_dir_merge_list modbus/
# Include sensors (all in a seperate *.yaml)
sensor: !include_dir_merge_list sensor/
Here the modbus

For some sensors you might need/want a template creation.
So here i created another folder called sensor
In there i got the isg.yaml for sensors.

Here is a sceenshot of my folder and file structure:
Lovelace:
Most of them are entities or sensor cards.
The heat production/warm and ratio cads are buttons as they look nicer.
The set temperature is the number box card add on from HACS.
Maybe check the grid card as well. Here you can use grid / in / grid to sort better.

Hi armin,
Beautiful work! I’ve used most of your code with a few tweaks (i dont use HK2, but HK1 etc.).
But I can’t get the Aktueller Betrieb to work. I also dont get any data back when I check it manually with a Modbus reader;
Any ideas?
Afternoon,
HK1 - Heat circuit 1 from the pump to the “boiler”
HK2 - Heat Circuit 2 is the ground heating inside the house.
About “Aktueller Betrieb” its the operating status of the pump. Betriebsstatus called in German.
You can find it in the Sensor.yaml

Hope this explains.
Maybe you have a different register depending on the type of pump.
I took it from here and focused on WPM system
cheers A
Glad it worked out!
Excellent Ratio you have. Seems to be warmer in your Area.
We got loads of snow today in Switzerland
Only thing i am missing is the second value of the summaries from the ISG.
If you scroll up on this topic you find a post. 11 days ago.
Maybe you stumble over these registers. Please let me know if you do so.
cheers A
