Electron

That looks interesting... 😛

Can you please set the DEBUG environment variable to * and post the output?

That looks interesting... 😛
It isn't electron specific, happens with regular node too!

It isn't electron specific, happens with regular node too!

Wasn't trying to imply that it was, just was curious what you're working on.

That is a bit of a strange-looking payload that the device sends back. IIRC even for protocol version 3.3 the version should be unencrypted before the payload, which isn't occurring here.

What are the options you're passing to the TuyAPI constructor? Try version 3.3 if you haven't already, and also double-check the key.

stefanjb-it · 2021-03-07T17:52:14Z

I have the same problem as @theLMGN:
When I connect to the light I only get junk data. I'm using a simplified version
of the example script.

Script:

const TuyAPI = require('tuyapi');
const device = new TuyAPI({
  id: 'bxxxxxxxxxxxxxxxxxxxx',
  key: '7xxxxxxxxxxxxx',
  ip: '1xx.xxx.xxx.xx',
  version: '3.3'});
device.find().then(() => {
  device.connect();
});
device.on('connected', () => {
  console.log('Connected to device!');
});
device.on('disconnected', () => {
  console.log('Disconnected from device.');
});
device.on('error', error => {
  console.log('Error!', error);
});
device.on('data', data => {
  console.log('Data from device:', data);
});

Everything I get as output:

Connected to device!

Yours looks slightly different as the version number is inside the payload. Not sure what's going on.

Could you link to a product page for your device?

stefanjb-it · 2021-03-09T05:27:27Z

I'm using these lights: https://www.hombli.com/de/products/smart-spot-rgb/

I have them linked with the tuya app and not with the original app of the manufacturer. I have also tested if it works with the original app, but the API returns the same junk data.

codetheweb · 2021-03-12T18:22:47Z

Could you email or message me the local key for your device so I can play around with the payload locally (assuming it hasn't changed since your last post with the debug log)?

stefanjb-it · 2021-03-12T19:59:25Z

@codetheweb I mailed you the local key and the id to the email on your website.

codetheweb · 2021-03-14T17:14:54Z

Thank you, I'll try and take a look soon.

codetheweb · 2021-03-14T19:05:46Z

I've played around with the two strings from the above debug output and I have no idea what's going on.

Could you provide a longer debug output? Multiple GET payloads between changing a single value on the device would be helpful as well. It looks like the device doesn't respond to heartbeat packets either?

Thank you. Could you send a GET request, change only one attribute of the device through the app, then send another GET request? Trying to see what changes.

Here is the script:

const TuyAPI = require('tuyapi');

const device = new TuyAPI({
  id: 'xxxxxxxxxxxxxxxxxxx',
  key: 'xxxxxxxxxxxxxxxxxxx',
  ip: 'xxx.xxx.xxx.xx',
  version: '3.3'});

// Find device on network
device.find().then(() => {
  // Connect to device
  device.connect();
});

// Add event listeners
device.on('connected', () => {
  console.log('Connected to device!');
  device.get().then(status => console.log(status));
  console.log("end");
});

device.on('disconnected', () => {
  console.log('Disconnected from device.');
});

device.on('error', error => {
  console.log('Error!', error);
});

device.on('data', data => {
  console.log('Data from device:', data);
});

Thank you.

Several of the packets are the same in both the on and off scenarios, so I'm a bit stumped. That would imply that the device isn't actually sending data about whether it's on or off.

Could you fetch the local key again to make sure it hasn't changed? Decryption should fail if it's wrong and not just return junk data but that's the only thing left that I can think of to try.

stefanjb-it · 2021-03-21T16:47:48Z

@codetheweb The key has changed from yesterday to today, but I don't know why. The API is now working without a problem. 👍 Big thank you for the effort.

codetheweb · 2021-03-21T17:48:40Z

Glad it's working now 👍

codetheweb · 2021-06-01T22:20:37Z

@pinkfloydFR please run your script with debug output enabled (DEBUG=*) and post the result in a new issue.

wojtulab · 2021-10-12T11:52:43Z

hello,
I've the similar issue.
My device: wifi socket with firmware 1.1.7

node -v
v14.17.3 (inside docker)

I've another 11 similar devices with 1.0.3 firmware that works normally.

codetheweb · 2021-10-17T17:47:50Z

@wojtulab can you double-check the local key? What do you mean by a 1.x.x firmware?

pinkfloydFR · 2021-10-17T19:32:56Z

I can reply to this, i already double checked my api, and i am sure is good as i can control my roller with the extension in HA

wojtulab · 2021-10-19T08:12:32Z

@codetheweb double checked, its ok.
Moreover I removed the socket and re-add with new keys.

The situation is the same.

By 1.x.x firmware I mean in Tuya app section firmware inside my device:
Main module: V1.1.7
Module MCU V1.1.7

No details, no follow up infos. closing. Please reopen if still relevant and happening with most recent versions.
