error on second handshake

[dvelayos]

recently,, i've updated HA to 2022.4 version; with the upgrade, the HomeAssistant-Tapo-P100-Control integration stopped working, so i updated everything (the integration, the PyP100 library) in order to get it working again

i've managed to get the plugs recognized at start (the setup_platform method goes ok with my 4 switches), but, when HA invokes the update method of each one, on the P100Plug class instances, it raises an exception on the handshake; i confirmed this error with this simple test code:

# Setup connection with devices/cloud
p100 = PyP100.P100(ipAddress, email, password)

try:
    p100.handshake()
    p100.login()
    data = p100.getDeviceInfo()

    encodedName = data["result"]["nickname"]
    name = b64decode(encodedName)
    print(name)
    p100.handshake()  """this line throws an exception"""
    p100.login()
except Exception as e:
    print("Could not connect to plug. Possibly invalid credentials::{}".format(str(e)))

the error is raised on the second handshake; the PyP100, on the handshake method, tries to recover the result;

encryptedKey = r.json()["result"]["key"]

but the result subindex does not exists; the response is

{'error_code': 9999}

i've managed to get it working modifying the update method, adding a try-catch on both methods (handshake and login). It seems that the second handshake-login invocation raises an error for some reason (i don't know if its a problem of timing, or something related with a new firmware)

anyway, it seems that those invocations are not needed for the tapo p100 in order to work (i've tested it and the switches works like a charm, even throwing both exceptions)

def update(self):
     try:
         self._p100.handshake()
     except Exception as e:
         _LOGGER.error("handshake error:{}".format(str(e)))

     try:
         self._p100.login()
     except Exception as e:
         _LOGGER.error("login error:{}".format(str(e)))

     data = self._p100.getDeviceInfo()

     encoded_name = data["result"]["nickname"]
     name = b64decode(encoded_name)
     self._name = name.decode("utf-8")

     self._is_on = data["result"]["device_on"]
     self._unique_id = data["result"]["device_id"]
