Hi dev, good day, i hv problem with version 3.4, with response when try to get statu of the device
set_status() result {'Error': 'Network Error: Device Unreachable', 'Err': '905', 'Payload': None}
by the way i hv information he tuya device after did the scanning :

pls need help

The 3.4 devices will require the "local key". Did you run wizard, python -m tinytuya wizard to get the keys?

[onenazlyhelmy]

I ran the wizard, Actually, my point is, i try to get device status locally(LAN) by trigger request on port 6668, the response still the same..i check the source code print out manually, i can seethe payload is empty, like :
ayload > MessagePayload(cmd=16, payload=b'{}')
IP: 192.168.0.10, Socket port: 6668
IP: 192.168.0.10, Socket port: 6668

You can turn on the debug mode either via command line:

python3 -m tinytuya scan -d

or via code - something like:

import tinytuya

print("TinyTuya (Tuya Interface) [%s]\n"%tinytuya.__version__)
tinytuya.set_debug(True)

d = tinytuya.OutletDevice(
      dev_id=DEVICEID,
      address=DEVICEIP,
      local_key=DEVICEKEY,
      version=3.4)
print(d)

print(d.detect_available_dps())

print(" > Fetch Status < ")
data = d.status()
print(data)

I scanned, and result found the devices:

local_key='0123456789abcdef',

This is not a valid local key. If you change it just to keep from posting the real local key, that's fine, just want to make sure you know that 3.4 devices require a valid local key to work at all.

Once you have the real local key, set up a monitoring loop to see if the device is emitting anything:

import time
import tinytuya

d = tinytuya.Device( 'DEVICEID', 'DEVICEIP', local_key='DEVICEKEY', persist=True, version=3.4, connection_timeout=1 )

print( d.status() )

print(" > Begin Monitor Loop <")
pingtime = time.time() + 9
polltime = time.time() + 3

while(True):
    if( pingtime <= time.time() ):
        payload = d.generate_payload(tinytuya.HEART_BEAT)
        data = d.send(payload)
        pingtime = time.time() + 9
        if data:
            print( data )

    # only needed for devices which do not update asynchronously
    #if( polltime <= time.time() ):
    #    polltime = time.time() + 3
    #    print( '================' )
    #    print( d.updatedps([17,18,19,20]) )
    #    print( d.status() )

    data = d.receive()

    if data:
        print( data )

I have exactly the same problem, did you find a solution?

Saving device snapshot data to snapshot.json

[uzlonewolf]

The scanner requires a devices.json file in the working directory. Make sure that file exists and contains, at a minimum:

[
    {
        "name": "My Device",
        "id": "bf5e9d230926e6b12fojsu",
        "key": "key8u54q9dtru5jw",
        "mac": ""
    }
]

[uzlonewolf]

Also, what type of device is it? Bluetooth/Zigbee gateways do not respond to status() requests.

[hamed-jamali-software]

Where is this file created?

python -m tinytuya scan -d

The lamp device is Wi-Fi and works well in the original software tuya
Purchased from Amazon today

Hi @hamed-jamali-software

The devices.json file is created when you run the setup wizard (python -m tinytuya wizard) and it is created in the local directory where you run the script.

A snapshot.json file is created when you run the scan as you mention, also in the local directory where you run the script.
