Does anyone with a S1255 get values in the BE1/BE2/BE3 (current) sensors? Mine are all 0 which is the same as when I check through the myUplink API. Current Power (EME 20) is also 0.
I got them working on a S320, but they never go below 2 A, even when the heat pump isn’t running. Are you sure the CT-clamps are connected?
Does anyone know how you change the set point for the room temperature on a S320? It’s the value marked in the image.
This is my experimental setup for power usage, derived from 1903 (current) address using P(kwh) = U * I * 1.732 / 1000 equation for three phases. Current is register 1903 divided by 10. I have SMOS40 and Nibe s2125. So far looks like a good estimate.

Utility meters should use delta setting:

Within how long should I be able to see any results and/or is it possible to share your complete configuration?
The only thing I’m really interested in is somehow getting the COP value.
Curent power is sampled every 60 seconds, so it should be there quickly(2 minutes). Energy registers change once an hour and is sampled every 15 minutes, so it will take longer. Utility meter updates when energy changes , could take an hour.
COP would be total energy out divided by total energy in. COP Value for previous hour would be sum(energy produced registers) / sum (energy used registers)
Something like:
- platform: template
sensors:
cop:
friendly_name: 'Last hour COP'
entity_id:
- sensor.nibe_in_energy_hot_water
- sensor.nibe_in_energy_heat
- sensor.nibe_out_energy_heat
- sensor.nibe_out_energy_hot_water
value_template: "{{ ((states('sensor.nibe_out_energy_heat')|float + states('sensor.nibe_out_energy_hot_water')|float) / (states('sensor.nibe_in_energy_hot_water')|float) +states('sensor.nibe_in_energy_heat')|float))|round(3) }}"
unit_of_measurement: ""
You would probably also need to add additional heat to the energy in values

@alfabetagama Thank you so much.
Big fat typo at this end with the IP address, so that should be sorted out.
Thanks also for the COP part, will report back if I get it up and running.
I couldn’t get values in BE1/BE2/B3 until 
current sensors have been installed. Now 
i wonder if the reading can be used to calculate a total house energy consumption. The sensors are installed on 3-fase input lines for monitoring and balancing the current loads. How else you can use this data. e.g. hourly consumption on individual phases ?
So, I have it up and running.
After some trial and error, I now have Total COP, Heating COP and Hot Water COP. Thank you again @alfabetagama for the directions.
For the charts I used ApexCharts Card by @RomRider (via HACS)
And I’ve added below code to my configuration.yaml:

Great, thanx for the code, it will save me some time :). Heating COP looks pretty good.
Hi, I have the integration up and running for couple of weeks. My system is F2120 with SMO S40, modbus over TCP - wifi connection, but I tried LAN as well. All works fine, but i get random unavaliability periods of the modbus data. Sometimes it is a minute sometimes it is 5 minutes. Sometimes it keeps on reocurring several times after each other on other ocasions it runs smoothly for a hour. As can be seen on the defrosting entity. The gray parts are those which state unavaliable.Anyone with a similar problem? Any suggestions where to look for the reason or how to solve the problem?
I think it is a Nibe thing. I also have frequent timeouts on modbus. If you have terminal installed goto config directory and run:
cat home-assistant.log | grep modbus
or
tail -f home-assistant.log | grep modbus
Thank you very much for your help. But I did not succeed after trying to run those lines in terminal response was:
But it coudl be that I did something wrong.
I found the log in HA and found for NIBE this errors:

I tried to add all 4 four entities heating IN/OUT and hot water energy IN/OUT. 3 of them work and the heating energy IN keeps on going into unavaliable...Hi, I’m new to HA and am having trouble adding my Nibe S320 + F2040.
The majority of the 790+ entities are unavailable. I have managed to adjust the heating curve slider (-10 to +10 - “Heating offset climate”) and I have managed to add some working sensors in YAML like hot water stop / start temperature values, BT25,BT6,BT7 sensors etc.
The S320 display has a card with the COP / total COP value, but I can’t figure out how to get any energy metric or value from the S320 to show in HA.
Would anyone be able to point me in the right direction? Any help would be appreciated.
EDIT: Forgot to add I’ve been reading for hours and trying different solutions, I’m not trying to sneak an easy solution in here, but I’m a little lost.
Is this modbus integration? What is the home assistant version?
This integration is for Nibe heat pumps that have tcp/ip connections, like the S series pumps.
At the moment, I’ve managed to add a whole bunch of sensors through Yaml using the MODBUS S-SERIES pdf chart, but I simply can’t get any sensors about power consumption / usage to load. It always shows as unavailable.
The pump is added through integration modbus - tcp/ip connection.
EDIT: Tried address:
1806 - Nibe Power - not quite sure what this measure but it only reads 0.2-0.6KW
2166 - Instantaneous used power - unavailable
2176 - Current power - unavailable
2178 - Total average power - show 0.0W
2180 - Total energy - show 0.00KW
And the posted above: 2291, 2293,2299,2305 and 2307 all these are unavailable
