After also restart of the nibe the readings came back. I’ve seen this once before now that after a ha powercycle the nibe modbus service seems to crap out… Maybe it gets bad input/requirests from ha and can’t handle, but it also does not reset.
Actually, I tracked the devs. And they asked for, and I supplied them with, some MODBUS stuff for SMO S40, and there are some other S models in the works too.
At first, it will be manual install, because also they need to build MODBUS over TCP, so it will be a dev version (or so I hope) but eventually it will perculate into HA proper I am sure.

Likewise, I provided them with registers from my heat pump.
Id like to change ”heating curve offset” value from dashboard, what is simpliest way to do it? Now i have made automations to write holding registers most used temperatures, but it would be nice to have some slider or enter a numeric state.
Edit: maybe moving ”heating curve offset” from sensor config to a climate is what i looking for?
@Toni_Karja - For which model. Is this? And Can you share your modbus conf and automation yaml code?
Thanks!

I have SMO S40 + F2040. how can I provide them info or volunteer for testing?
Hi,
got my fs2021 including SMO 40s installed this week. Fine to have some fellows with nibe heatpump around. Hello to you all!
At first I was very disappointed with the myuplink stuff. Premium subscription etc. But since I found this thread I mad a lot of progress. I can read and write registers using HA modbus integration (to write I have to call the modbus write service).
One question though: How can I write form the UI e.g. set a temperature?
Kind Regards,
Marco

Hi Marco, you can probably use a thermostat card to set temperature.
How are you connected to the heat pump? Modbus TCP?
Hi Waleed,
Yes Modbus TCP. Thanks got it. Works like that:

input_type: input
count: 1
data_type: int16
max_temp: 50
min_temp: 40
offset: 0

Have a look at mushroom cards on HACS. They have some very nice “buttons” compared to the standard HA buttons.
https://github.com/piitaya/lovelace-mushroom
The climate card could be useful and its minimalist
This is sort of anoying. Modbus platforms are not really working form me. It actually needs a different address for each card. In my example there are two climate cards configured but only one shows up, that is due to using the same address to read the value (current upper temperature).
Now I tried to use the same address for address and target_temp_register but it reads some weird value there…
Also, I’m still lacking the connection from the registers and its description and what the actual effect on the system is. Is there any sort of enumeration for the values in any doc?
I like to disable the time programs on my smo 40s and use HA to configure different scene’s but I’m totally lost with all the parameters… does anybody have some suggestions how to set which parameters on the heatpump to:
- Only do hot water
- Do hot water and heating
Many thanks,
Marco
Sorry, no help here but emotional support 
.
I’ve asked aftersales support now twice about more details documentation on modbus parameters, but I only got the half baked documents back and the advice to export the register.
What needs to be clear is that the register (of smo s40) returns different sets based on features enabled and type of nibe heatpump attached.
Myself, smoS40+s2125—12, can’t see the register to read or set the target setpoint somehow.
Also the RMU-s40 sensor values do not appear.
So I have made a baby step progress. I created a switch to control the operating mode.
The operating mode has 3 positions; Automatic, Manual and Additional heat.
However I only know how to create a 2 way switch so can switch between Automatic and Manual only.
Anyone know how to create a switch with multiple states?
Are you talking about the Operating Priority?
Have you considered using a switch? You can turn on and off but you will not be able to set the temperature.
I have the following code for “More Hot Water”
# Switches

But all sensors are unavailable. It shows error Connection to (192.168.1.8, 502) failed: [Errno 111] Connection refused. MODBUS in SMOS40 is enabled. Is that I should do a dump of AMS10-12 registry and edit my config?
Now I tried config from this topic (the first one) and everything is also unavailable.
It seams every heatpump has it s own register mapping. So yes, you have to export the file.
