tuya gateway subdevice not found

Describe the bug I have a json file from tuya smart data, which contains all device ID’s and the localKey for the gateway. Tuyapi can connect (and/or discover) the gateway, but can not get data from any subdevice. It may be the fault of my coding…

To Reproduce DEBUG=* node tuya_gw.js (I posted the code below)

Expected behavior I expected to get any available dps data from the given subdevice.

Tuya smart app shows the very same device ID’s as I see in the json file. Sub devices regulary send broadcast messages:

Please help me by finding the right code to get dps data or by improving tuyapi to support this kind of device.

@danielgiovanni : Unfortunately I was not able to solve it yet. It appears, that even the tuya smart app didn’t communicate to the gateway directly, but through the tuya cloud.

I plan to create an artifical block towards the internet on the AP the devices connected to (Phone, tuya GW), and see if the phone tries to communicate the gateway directly if there is no internet connection to the tuya cloud.

If this didn’t help, I don’t know what else can I do.

I found something interesting that the same code test with tuya wire zigbee hub and result is different.
