You need rs485 module.
I am using the model SPRSUN CGK-040V3L-B
12kw, R32, motherboard of ELECHICO model CC902, Elfin-EW11, Sprsun Heat Pump App, NO Tuya
Can I integrate the heat pump into Home Assistant with the Elfin via Modbus with your yamel?
Or should I still buy the Zlan 7110m?

Or is it better to use an esp?
Thank you for your work, I look forward to your answer!
I use the original elfin connection with heat pump : GitHub - PiterPiotr/Sprsun-PC: Integration of the Sprsun CGKxxxV3L-B heat pump with HA
@Piter123 I would like to ask you to share more details, I have bought this heat pump CGK-040VL3-B and in one week it will be installed. You are saying that the heat pump has everything out of box, there is EW11 already installed so I do not need to buy something extra hardware e.g. rs485 module ? I am familiar with HA, I have done a lot of stuff but I havenât used modbus before, so it would be helpfull if you can share how I have to proceed to successfully connect the pump to HA in a few steps. Best regards
Yes, EW11 was included. Once you start the pump, install the application, check that everything works, make a copy of the EW11 settings and configure Modbus in EW11 according to the configuration Sprsun-PC/ew11_configuration.jpg at e37828738ed189ad51b423344d2010a8764db7a9 · PiterPiotr/Sprsun-PC · GitHub
Unfortunately, the apk configuration needs to be removed.
Powerworld R290 heatpumps seems to use a similar control board with similar modbus interface.
Any chance getting this Powerworld heatpump modbus interface supported by your code blackscreener ?

@Piter123 I forgot to save the original settings, would you have a backup of them please 
Hi, could someone please point me in the right direction.
Iâve never done this before but Iâm trying to intergrate my heat pump into HA. Iâve been given a modbus registry and have been playing around trying to get a sample of code to work. Could someone please check and guide me, this is an example of what iâve tried:
modbus:
- name: HP+Link
delay: 5
timeout: 5
type: tcp
host: 192.168.0.169
port: 502
switches:
name: âUnit On or Offâ
unique_id: âunitonâ
slave: 1
address: 0
write_type: coil
command_on: 1
command_off: 0
verify:
input_type: coil
address: 2
state_on: 1
state_off: 0
Many thanks for any help, iâd just love to get any data back from the heat pump, atleast just to prove iâm in the right direction and my physical setup is correct.
Hi, the repo is not avaiable 
try to connect to cc902 board. Cant find example codeâŠ
Do you still happen to have that PDF??!
PW58329âCC1010BâMODBUS.Communication.Protocol.V1.0_POWER.WORLD.R290.1.pdf
I really would like to know the Modbus protocol for the CC1010B!!

Yes.
Iâve put it on onedrive and here is the shared link (.pdf)

Thanks!!!
Still getting rubbish data but starting to suspect faulty ESP / rs485 moduleâŠ
Replacing and at it again
which heat pump do you have?
My understanding is that CC1010B pcb board is used in many different heatpumps(Sprsun, PowerWorld+++).
I assume that these vendors may implement different software and interface modbus registers of the CC1010B PCB.
The file i supplied was for a Powerworld R290 heatpump
Hi!
Blockquote
Im trying to get it to work on a Lyfco brand (sold in Sweden)
Successfully attached now⊠seems like itâs sending a stream of broadcast (for updating the display I assume).
Canât make any sense of it, but on the other hand it my first attempt to backwards engineer a modbus protocol
Did you get your code to work ?
Henrik which mainboard do you have for your lyfco. I have a model described as pw010-kzxyc-c with the mainboard being XINC-1630P. Unfortunately my display stopped working so I was hoping to get it working better in HA so I can adjust parameters and do more than I can with the crappy Tuya integration.
Hello,
I want to integrate my Sprsun heat pump into HA, I saw your post, but unfortunately your github is no longer active. Can you help me? I already have EW11 connected.
Thank you!
@Piter123 Im in the same shoes as @costi.george. I got stuck. Could you help me to integrate Sprsun heat pump into HA, please? Thanks in advance
Iâve re-uploaded the yaml file. Iâll add a description in the future.
PiterPiotr/SPRSUN-CGK-V3L-B-Elfin-EW11: This topic concerns the integration of a Sprsun heat pump with a color display. Communication is via the Elfin EW11 module - settings: EW11_1,2.
