Modbus configuration for NIBE S series heatpumps

Note that this was done for a NIBE S1155 PC, but would expect the majority to work for other heatpumps from the S series as well.

After combining information from the modbus documentation from NIBE themselves, the exported CSV from the heatpump and a lot of trail and error (with the assistance of myuplink), I would like to share the current yaml I have for at least the majority of sensors as included in the ‘info’ menu.

More than willing to receive any feedback and or comments, particularly as I would not consider myself experienced with this kind of stuff yet, hence any best practices are welcome.

Added comments where possible, including some deviations (mainly data type) between the modbus reference and what I ended up using, in the comments you’ll find what is included in the most recent version of the reference document.

Hey this great! By far very extensive. I too have a similar heat pump. However I didn’t use all the registers as some are not necessary for my purposes.

Have you been able to write to the Pump?

I have some different values for some of the registers, maybe because I have the S1255?

  - name: "Heatpump - Priority"
    unique_id: "operating_prioritisation"
    data_type: int16  # int8
    # 10: Off, 20: Hot Water, 30: Heat, 40: Pool, 60: Cooling
    address: 1028
    input_type: input  # R/W
    scale: 1
    precision: 0
    state_class: measurement
    slave: 1

You have 50 for Cooling.

  - name: "Heatpump - Hot Water Demand"
    unique_id: "hot_water_demand"
    data_type: int16 
    # 0: Small, 1: Medium, 2: Large, 4: Smart Control

    input_type: holding  # R/W
    scale: 1

    state_class: measurement

I get 4 for Smart Control.

Check this list of Modbus registers. At least some from the common registers should work for you. https://partner.nibe.eu/nibedocuments/29795/M12676EN.pdf

I’ve been able to get a good amount of data from my Nibe S2125 now into home assistant; purely using modbus and the NIBE SMO S40 control unit.
You can enable modbus in menu 7.5.9 - set setting to “on” and your control unit will communicate modbus via the LAN. check the ip via DHCP (this can be found in menu 5.2.2).

Below the general registry list I could pull from the unit:

Hey Victor, have you been able to “write” to the pump or just get values?

What seems to be the power consumption issue?

I created a “Riemann sum integral” integration and it shows up in my energy tab.

The S2125 icw the SMO40 does not seem to have it available; I do not see it in my exported registry, and the ‘common registry’ list address in the pdf does not provide any value.
I also do not see it in the display interface on the SMO40.

I’d love to have it.

Do you have a power consumption display in the SMO40?

My system is different and doesn’t have an SMO40

Seems on my setup the power measurement points were not enabled. But there seems to be a menu under 3.3

@RemonG Thanks. copied/pasted your yaml for my SMO S40 + S2125 and it mostly worked.
However, some show as unavailable. Two if the more interesting ones amoung them.

PS: I just activated the NIBE today. Spent all evenings last week hooking it up.
I would not mind having someone experienced to PM some torrent of questions on settings.

I never got the power working, doesn’t seem part of the default internals.

The Compressor state you can use this:

- name: “wp Compressor Status”
unique_id: “wp_compressor_status”
data_type: int16 # uint8
# 0: Off, 1: On (Operate)
address: 1484
input_type: input # R
scale: 1
precision: 0
state_class: measurement
slave: 1

Tip start all your unique id’s with ‘wp’.

Thanks. That new address also gives unavailable.
How do you get those RAW modbus details dumped like you have on your first post in this thread?
Edit: the 1484 did work, but copy/pasting it from the text above give left-right (open/close) high double quotes instead of the programmes straight quotes.

Pity of the power use. I do also see in the manual you can get the AUX to generate a energy pulses. Both for electric energy and for heat energy, so you can calculate COP. I may build a ESP Home device for that later.

I wonder though, maybe if I already activate the AUX, it will show up in MODBUS. Again, how do you get those RAW modbus details dumped like you have on your first post in this thread?

Stick in an USB stick in the port (hidden behind the S40 plastic label), or remove the cover of the smo.

Insert a USB-stick in your SMO S40 display and go to meny 7.5.9 MODBUS TCP/IP.

Now you can export a list of all available Modbus addresses for your installation.

That’s sad, ask the devs?

But you have the SMO40?
Why don’t you try it and post results. Maybe even the code and we can see what can be done.

I just upgraded to ha 2022. 10.1, now modbus is having issues connecting to the nibe IP (fixed address) .

Anyone else?

Mine is working fine. Post the yaml part for your heat pump configuration.
