ValueError: check_hostname requires server_hostname with Roomba password.py

[danielkhan]

After the device was found, I am asked to press the home button. Once I press enter on the console, I get this error:

Traceback (most recent call last):

    main()

Same here!

What Roomba do you have? For new Roomba’s you have to use a different process, as described in the instructions.

The method you are trying only works on older Roomba’s.

[NickWaterton]

Ok, I have looked into this. There are two possible fixes, maybe one of you can test this out.

in file password.py

1. change PROTOCOL_TLS_ CLIENT on line 194 to PROTOCOL_TLS_SERVER
2. change context.wrap_socket(sock) on line 196 to connect.wrap_socket(sock, server_hostname=addr)

If you could try 1) or 2) above (but not both), and let me know which (if any) works, I will update the code. I can’t test it myself, as I only have new Roombas.

Ok, I have looked into this. There are two possible fixes, maybe one of you can test this out.

in file password.py

1. change `PROTOCOL_TLS_ CLIENT` on line 194 to `PROTOCOL_TLS_SERVER`

2. change `context.wrap_socket(sock)` on line 196 to `connect.wrap_socket(sock, server_hostname=addr)`

If you could try 1) or 2) above (but not both), and let me know which (if any) works, I will update the code. I can’t test it myself, as I only have new Roombas.

2. works for me, but "connect" has to be "context", so:

context.wrap_socket(sock, server_hostname=addr)

[paulwouters]

note i still had an issue of the script exploding because I have two roombas and one was downstairs on its charger, so I couldn't press the home button :)

[Idaho947]

You have to the button and after press enter so you have time.

[Gurbmeister]

I came across the same problem. although i got it through the cloud option :) nonetheless I checked these options. and both seemed to work.

I'm getting the same issue and none of the above solutions are working for me.

For 1, I get the Cannot create a client socket with a PROTOCOL_TLS_SERVER context (_ssl.c:809) issue. For 2, I get Connection Error (for <ip addr>): [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1006) when I change connect to context in the solution. With connect as the solution suggests I get a NameError as mentioned by @Idaho947.

I've got the S9+, and as a sanity check I also attempted all the same steps both with the vacuum linked and unlinked to my Google account.

I'd be happy to perform further troubleshooting steps as necessary

[NickWaterton]

@32nmud

The process you are attempting does not work on modern Roombas like the S9+.

For modern Roombas, you have to use the cloud connection method to get the password, as described in the documentation.

Wondering if for non-cloud Roomba connections, it makes sense to bypass hostname and certificate validity checks altogether? Heres what I use since these are all local roombas and I trust them ;-).

context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
context.check_hostname = False
context.verify_mode = ssl.CERT_NONE

context = ssl.SSLContext(ssl.PROTOCOL_TLS_CLIENT)
context.check_hostname = False
context.verify_mode = ssl.CERT_NONE

This is exactly what worked for me -- I have an iRobot SKU s955020

Trying this method with a Roomba 960, I get the following error now:
