Tapo C210 firmware 1.3.11 Invalid authentication data

[Pytoune]

Hi and thank you for your project.

I try to test it with the simple next script named "test.PY" :

from pytapo import Tapo
user = "admin"
password = "tapo_password"
host = "192.168.1.20"
tapo = Tapo(host, user, password)
print(tapo.getBasicInfo())

But I have the following errors :

python3 test.PY
Traceback (most recent call last):
  File "test.PY", line 7, in <module>
    tapo = Tapo(host, user, password)
  File "/usr/local/lib/python3.7/dist-packages/pytapo/__init__.py", line 34, in __init__
    self.basicInfo = self.getBasicInfo()
  File "/usr/local/lib/python3.7/dist-packages/pytapo/__init__.py", line 221, in getBasicInfo
    {"method": "get", "device_info": {"name": ["basic_info"]}}
  File "/usr/local/lib/python3.7/dist-packages/pytapo/__init__.py", line 85, in performRequest
    self.ensureAuthenticated()
  File "/usr/local/lib/python3.7/dist-packages/pytapo/__init__.py", line 51, in ensureAuthenticated
    return self.refreshStok()
  File "/usr/local/lib/python3.7/dist-packages/pytapo/__init__.py", line 70, in refreshStok
    raise Exception("Invalid authentication data")
Exception: Invalid authentication data

It seems like tapo c210 new firmware does not permit to login with the API as before ?

I have tested many couples user/password :

• admin + local cam password
• local cam user + local cam password
• admin + tapo password
• ...

Thank you for your help.

For firmwares that use encryption you need to use admin and your tplink account password for control.

Thank you first for your reactivity but it does not work, maybe it's me. tplink account password = tapo password = tplin community password ? I have modified it to try a more simple password without specials characters but it is the same. I use "admin" as user and "tplink/tapo/..." password.

Thank you JurajNyiri, it is solved by using last Pytapo version (3.3.18) with recent Python version (3.9). Thank you for your project which help a lot of people.
