try execute it with python 2.7

edit: updated the script to work with python 3 too

63

@jackdalma 2.7 is working , same output as you got … tnx

64

@jackdalma Home Assistant is working on python 3.5 so we have to do the same.
It looks like every device is different.
I will prepare new script and we will check if it will be enough. I’ll try to do this on the late evening.
@Modrica on other thread I have put the same script. Can you share whole output - at least ssl version?

65

@Modrica Can you check with python 3?

66

i tried with python3, same output as before.

67

@SebuZet here is response from 2.7

@Modrica @jackdalma @Nick2 Thanks for your help and testing connection scripts.
Is any one brave enough to check latest component from dev branch :smiley: ?

climate:
  platform: climate_ip
  config_file: '/config/custom_components/climate_ip/samsung_2878.yaml'

Next, open ‘/config/custom_components/climate_ip/samsung_2878.yaml’ file and change config data (host, token, mac or duid) and restart HA.

Let me know what we have to fix :smiley:

77

Hey guys,

Only way I can get it to work is to set

sslContext.verify_mode = ssl.CERT_NONE

I’ve tried the one from @SebuZet’s github dev branch: ac14k_m.pem
I’ve also tried getting the cert from my server using openssl using:

echo | openssl s_client -connect 192.168.1.106:2878 2>&1 | openssl x509 -outform pem

With both certs I get

TEST, Error creating socket

Traceback (most recent call last):
File “D:/ha/test.py”, line 35, in create_socket
sslSocket.connect((HOST, PORT))
File “D:\Python27\lib\ssl.py”, line 864, in connect
self._real_connect(addr, False)
File “D:\Python27\lib\ssl.py”, line 855, in _real_connect

File “D:\Python27\lib\ssl.py”, line 828, in do_handshake
self._sslobj.do_handshake()
SSLError: [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:727)

Can anyone confirm the cert they are using?

78

@SebuZet
i got this on log:

@Nick2 i’m using the one from SebuZet’s github dev branch

I noticed your ACs are returning: DPLUG-1.6

Mine returns DRC-1.00…

TEST, creating context
TEST, load verify location
TEST, set ciphers
TEST, load cert chain
TEST, wrapping ssl
TEST, connecting
DRC-1.00

@SebuZet

I tried your dev branch with my HA. Got:

ModuleNotFoundError: No module named ‘xmljson’

I renamed climate.py to climate_ip.py restarted HA and renamed back and restarted again and no more complaints. not sure how that worked…

I now get Error creating socket same as @jackdalma

I tried updating samsung_2878.py to use CERT_NONE but still no luck

def create_socket(self, init_message):
    sslSocket = None
    try:
        sslContext = ssl.SSLContext(ssl.PROTOCOL_TLSv1)
        #sslContext.verify_mode = ssl.CERT_REQUIRED
        sslContext.verify_mode = ssl.CERT_NONE
        sslContext.load_verify_locations(cafile = self._cert)
        sslContext.set_ciphers("HIGH:!DH:!aNULL")
        sslContext.load_cert_chain(self._cert)

Is deleting pycache folder enough to make my changes to samsung_2878.py take effect ?

81

I’ve updated files, @Modrica and @jackdalma it should work with your units.
@Nick2 If it will work for @Modrica and @jackdalma we will back to your configuration. Try latest version. If you modify my last script and use sslContext.verify_mode = ssl.CERT_NONE can you connect with your device?
