Cannot connect to smart plug over local API

apach3guy commented 1 month ago

Having issues connecting to a smart plug over the tuya local API. I confirmed that I can connect to the plug over LAN on port 6668, so it should be supported.

root@odroid:~# nc -v -z -w 5 192.168.2.215 6668 Connection to 192.168.2.215 6668 port [tcp/*] succeeded!

I ran tinytuya in debug mode. It seems the plug is not sending any data.

DEBUG:building command 10 payload=b'{"gwId":"eb1f39ea47707b153elyqd","devId":"eb1f39ea47707b153elyqd","uid":"eb1f39ea47707b153elyqd","t":"1715306590"}' DEBUG:sending payload DEBUG:payload encrypted=b'000055aa00xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx' DEBUG:_recv_all(): no data? b'' DEBUG:_recv_all(): no data? b'' DEBUG:Error decoding received data - read retry 0/5

Here's the device info:

I'm using TinyTuya [1.13.2]

Hi @apach3guy , suggestions:

Verify local key including running wizard: python3 -m tinytuya wizard
Verify device version via scan: python3 -m tinytuya scan - and just in case, try different versions (see code below on how to specify)
Power cycle the device - this often fixes Tuya devices that end up in an unknown state but still work with cloud or respond to TCP
Make sure device doesn't need a firmware upgrade (via SmartLife App)


# Connect to Device
d = tinytuya.OutletDevice(
    dev_id='DEVICE_ID_HERE',
    address='IP_ADDRESS_HERE',      # Or set to 'Auto' to auto-discover IP address
    local_key='LOCAL_KEY_HERE', 
    version=3.3)

d.status()

Thanks. It works with version 3.4 only. I tried version 3.3 and 3.5 which do not work.

Thanks! What was the fix? Just switching to 3.4?
