Hi @SebuZet,
I’ll give it a go tonight.
ps. I’ve been attempting to build a server to mimic the AC. Once that’s build, you could test you component against that. (I’m using the nodejs client implementation build the server against.) Haven’t got very far though…
@Nick2 Great, updated version is available. If it doesn’t work you can try to modify the code to make communication working. When it starts to work I will put it into my component and we will have working component for old AC unit
Hi @SebuZet,
I’ve made some good progress tonight. After some adjustment of your code and disabling SSL verification, I’ve got it to connect to my AC.
What I’m not sure how to do is loop correctly to get the responses from the AC. (like the while loops in your code)
You’ll see I’ve included the server responses in comments.
Hopefully this is a good start
Here’s my code: https://drive.google.com/open?id=17a0nLfIWkR-E8JZ7xP7ne8IcEY-F8gFz
Hi @Nick2 This is very good start. This is almost finish 
I’ll try to integrate this into component and let you know.
Hi @Nick2, we can make next step in testing new solution. If you want to test new component please get it from my GitHub dev branch. Please make ‘climate_ip’ folder in your config/custom_components folder and copy all files.
In configuration of your HASS put section:
climate: platform: climate_ip config_file: '/config/custom_components/climate_ip/samsung_2878_2.yaml'
Next, open ‘/config/custom_components/climate_ip/samsung_2878_2.yaml’ file and change config data (host, token, duid) and restart HA.
If you want to make same code modification you can go to connection_s2878.py file and look at execute method 
Let me know what we have to fix

Interesting blog about Samsung AC 2878
Thanks but without device it won’t help me. I need help from someone who can write python code (connection part) and have such device at home. Maybe @Nick2 will find a little time to test and fix connection part.
I’ve just take a look at your dev branch. Wow you’ve done some work there!
I’m keen to try it out over the next few nights. I’ll let you know how I go.
Is there a way to test a component outside of HA so I can run it through a debugger?
@Nick2 To be honest, I have no idea how to debug under HA. I was developing it outside HA and after all I’ve added imports from HA.
Without connection everything looks good. If you edit connection_s2878.py file you can remove comments in lines 117, 118, 141 and restart HA. You will see climate device with data taken by you from your device (hardcoded xml).
So the last thing to do is to add communication with device.
You can print variables init_message and message from execute method to see what data will be send to device. In my system in logs everything looks good. We only need to communicate with device
To make it easy we can extract communication to separate file and test/debug it. Unfortunately I don’t have device to play with 
@SebuZet @Nick2 I removed comments and are getting this error:

@Modrica Thanks (removing comment (#) from lines 118 and 141 will comment out all communication stuff.
Can you please download and check this script and share output
EDIT: of course you have to change variables HOST, certfile, token, duid to meet your configuration
@SebuZet I have som issue I need to solve her, I think it is just my os installation not your code… Need to solve python-openssl

@Modrica It looks like it depends on system/python version etc… Just remove this line ( or change to -1) and try again
@SebuZet I changed it to -1 and here is result:
