Found device, but Network Error: Device Unreachable, Err: 905

[davrivas80]

Hi there.

I am trying to connect locally to a Zigbee Gateway with no avail.

This is my simple code:

gw = tinytuya.Device( GATEWAY_ID, address=GATEWAY_IP, local_key=GATEWAY_KEY, persist=True, version=3.4 ) print( 'GW IP found:', gw.address ) print(gw.status())

This is what I get:

GW IP found: 192.168.1.80 {'Error': 'Network Error: Device Unreachable', 'Err': '905', 'Payload': None} Process finished with exit code 0

With DEBUG ON:

Any clue?

It looks like either the IP address is wrong, or that gateway does not support local control. Does the scanner python3 -m tinytuya scan find it?

[davrivas80]

Yes, scan can find it. IP address is correct.

It happens the same with three of my devices: a Zigbee Gateway (the above example, not really interested in polling it, but since it is the gateway to other devices if it is not reachable maybe those subdevices won't be either), a Smart Alarm, and a Smart Switch.

I have other devices I can reach without problem (some smart bulbs).

That particular "socket unable to connect" error only happens when a TCP connection to the device cannot be established at all - the IP address is wrong, the device is not listening for incoming connections, or a firewall is blocking the connection. I'd power cycle the device and try again. If it still does not work, what does the scanner say the 'Status:' is?

Without modifying a single line of my code I managed to access the Zigbee Gateway and subdevices... I think it has something to do with the Tuya App. It seems a bit odd since it is something I had already discarded since the problems persisted even with my phone disconnected
