Credentials for H200

[bhumerca]

Hello!

I have 2 Tapo H200 and when trying to discover devices I got credentials error. I entered right credentials (tested with log in tapo app). Did something changed?

I get msg that device on my IP model H200 and then Device response did not match our challenge on ip 10.145.18.189, check that your e-mail and password (both case-sensitive) are correct.

@bhumerca Can you run the discover with the --debug flag and post the output here? Scrub your personal information, but I'm looking for the encryption information, but ai need to see the whole response.

Here is the output from a manual discovery using python-kasa with DEBUG logging enabled.

Command:

• run inside a small async script that calls Discover.discover(credentials=creds)
• kasa version: 0.10.2
• device: Tapo H200 (SMART.TAPOHUB)
• platform: Windows 11, Python 3.11

I have redacted my device_id and owner fields.

@bhumerca And you're importing Credentials to build the credentials correctly assigning them to creds? It looks like it connects with the default credentials but fails when trying to use your credentials.
