A new way of getting deviceId and localKey

[SleepWalker]

Hello, I've found out, that an official Smart Life app shows you deviceId. I've tested that deviceId with tuya OpenAPI and it works (at least for my smart sockets). This means, that you can get localKey from an OpenAPI /v1.0/devices/{{device_id}}.

I think, that this may be useful to simplify tuyapi setup workflow.

The new setup will consist of three steps:

• after creating app on iot.tuya.com and getting key/secret, you need to link your devices, but instead of doing that with @tuyapi/cli, you should "Link device by Tuya Smart App Account":
  
• then you can grab id from an app. From the main screen tap on device you interested in, then tap "edit icon" to get to the screen where you can manage/share/rename device. On that screen there is "Device information" menu option, where you can look up for the deviceId:
  
• finally request device info from tuya OpenAPI, where you can get localKey value:

I tried this. I am getting: There was an error in evaluating the Pre-request Script: TypeError: Cannot read property 'sigBytes' of undefined. when trying to make the get request. I also can't tell what I am suppose to use as schema value when making the request.

This could be really useful @SleepWalker, thank you for researching it.

tuya-cli link still has issues occasionally for some users, so this could be a great alternative.

I'll take a look at some point this weekend.

i would try your method, but im noob . It's ok for my virtual id, i have found.

@etttoutoi This quick start guide from tuya has all the info you need for using postman to get the local key. Basically:

1. Install postman
2. Download and import the environment and collection in postman
3. Set up the variables according to your tuya developer profile client_id, device_id (from the app as described in this post), schema, and url (region based, i.e. https://openapi.tuyaeu.com for EU)
4. Run the access_token task in collections in postman
5. Run the {{url}}/v1.0/devices/{{device_id}} request to get your local_key

Here is a gist, that demonstrates how to get localKey and then tries to use it with a demo code from tuyapi README:

I've successfully turned on/off my socket using demo.js from that gist 🎉

@SleepWalker so after looking at this a bit, it seems that while linking your TuyaSmart account to your SaaS instance works fine, there's not a programmatic way to get all device IDs. /devices throws an error, and /devices?schema=TuyaSmart gives a permission error. Did you find a good way to list devices?

Ideally, the user would be able to link their account through the web interface and then run one tuya-cli command to list devices; without having to manually find and copy device IDs.

[SleepWalker]

@codetheweb you can use {{url}}/v1.0/users/{{uid}}/devices for that. But, the only way to get uid I know, is by copying deviceId from an app and than get uid field from device info request.

So the user should copy deviceId from any random device, that he had connected to his account. And then it can be used to list all other devices

I've added demo script in gist, that lists all the available devices:

deviceId can be obtained programmatically using the cloudtuya library, by providing it with your account login details (smart_life, tuya smart app) it will list the device ids for all connected devices, which can then be used here.

So close, but so far on this one. Fell at running {url}}/v1.0/devices/{{device_id}} with the error below. The access_token task had run successfully so I have my Postman environment set up correctly. Anybody seen this error?

[SleepWalker]

@tim-jc looks like you've forgot to link your smart life account to your tuya dev account (https://auth.tuya.com/). See the issue description for the screenshots.
