Intermittent failures in Home Assistant - "error while get mqtt config" about tuya-iot-python-sdk HOT 7 OPEN

it is still happening here 17 March 2022 fully patched

from tuya-iot-python-sdk.

Many people with such problem last few days, but no way to fix it ((

Same issues here. All devices seems to lose connection, after restarting Tuya integrations it works again for some time (a few hours). It's absolutely not stable at this moment. Problem with 11.5 and with 2021.1.12. It looks that there are problems with the Tuya API/ Tuya Cloud and has nothing to do with the version of Home Assistant nor OS-version. I have same problems with my test-box (used old version and new version and different versions of OS).

I'm also having the same issue all of a sudden. Added in some logging to the openmqtt method _get_mqtt_config() to see what the error from the API is:

{'code': 1010, 'msg': 'token is expired', 'success': False, 't': 1639929045868}

So it would appear the auth token is expiring and not being correctly refreshed by the client.

I asked IOT.tuya support about this, they ask me "Where did you see the API you called，Could you please provide the address you saw" ;)))

This was fixed in tuya-iot-python-sdk v0.6.6 which was included in Home Assistant 2021.12.6.

Looks like the url to refresh mqtt config is wrong : https://developer.tuya.com/en/docs/cloud/c2c2630d7c?id=Kb68mozbi3foh
Or am I mistaken here?
The code seems to make requests to (openmq.py - l25-26)

TO_C_CUSTOM_MQTT_CONFIG_API = "/v1.0/iot-03/open-hub/access-config"
TO_C_SMART_HOME_MQTT_CONFIG_API = "/v1.0/open-hub/access/config"

These URLS are used at lines 62-81:

    def _get_mqtt_config(self) -> Optional[TuyaMQConfig]:
        response = self.api.post(
            TO_C_CUSTOM_MQTT_CONFIG_API
            if (self.api.auth_type == AuthType.CUSTOM)
            else TO_C_SMART_HOME_MQTT_CONFIG_API,
            {
                "uid": self.api.token_info.uid,
                "link_id": LINK_ID,
                "link_type": "mqtt",
                "topics": "device",
                "msg_encrypted_version": "2.0"
                if (self.api.auth_type == AuthType.CUSTOM)
                else "1.0",
            },
        )

        if response.get("success", False) is False:
            return None

        return TuyaMQConfig(response)

This code doesn't match the actual documentation
