[tjengbudi]

hello, i have 3 smart plug by tuya system. and 2 of them is working properly. one of them have weird behavior. it looks like something in the process have some chinese character.

the error i get is

021-01-14 08:23:02 ERROR (MainThread) [custom_components.localtuya.common] [eb1...hz1] Connect to 192.168.1.113 failed

payload = payload.decode()
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xc8 in position 3: invalid continuation byte

the 2 of them is connected properly, i got that error with text configuration. with ide wizard, just get error cannot authorized could you help me about this. i try to change the decoding (decode('utf-8'), error='ignore') but looks like i just do not know what i am doing

looks like it is bugs for some devices

btw i trying the tuyadebug and it can received the dps status from there. so i am sure devId and localKey is OK.

Can you post the DPS dump, you configuration and maybe some logs with the message localtuya is trying to decode (in debug mode) ?

[tjengbudi]

this is my setting in configuration.yaml for the smart plug. the ip, localkey and devid will be deleted

  - host: "192.168.x.x"
    device_id: ""
    local_key: ""
    friendly_name: "Plug"
    protocol_version: "3.3"
    entities:
      - platform: "switch"
        friendly_name: "Plug Piano 2"
        id: 1
        current: 18 # Optional
        current_consumption: 19 # Optional
        voltage: 20 # Optional

this is the dps dump

TuyaDebug (Tuya DPs dump) [1.0.0]

Device eb at 192.168.x.x key ax protocol 3.3 dev_type type_0d:
    DPS [1] VALUE [True]

    DPS [24] VALUE [15089]
    DPS [25] VALUE [1380]
    DPS [26] VALUE [0]

and this is the debug
