Tuya Developer Forum

Hi there,

I would like to write a SpringBoot3 application to control a device. I have properly registered and set up my device that I want to control in the Tuya cloud, and everything is working so far.
I have now checked out the tuya-sdk, the tuya-connector and the connector project from Github and integrated them into my project, so far so good. Everything is compilable, everything is wonderful.

I have also written a JUnit test to log in with my credentials, which was successful.

However, I now have a problem accessing my device.
I have executed all the instructions in the readme file of the tuya-connector project. But I still get this error (see below)
Can someone explain to me what else I might have to do to successfully run my test and finally get access to my device?

I work with SpringToolSuite 4.21, use Lombok version 1.18.30, Java version 17.
Somehow I have the suspicion that the two specified "add-opens"
--add-opens java.base/java.lang.reflect=ALL-UNNAMED
--add-opens java.base/java.lang=ALL-UNNAMED
from the readme file are not effective (I have specified them in the springtoolsuite.ini). Do I have to specify these two things somewhere else?

Well, you can configure the "--add-opens" startup option in SpringToolSuite4 as follows:

1. Click the start button in the top left corner to open Run Configurations option.
2. Switch to the 'Arguments' tab, add "--add-opens java.base/java.lang.reflect=ALL-UNNAMED
   --add-opens java.base/java.lang=ALL-UNNAMED", and then click apply.
3. Finally, start the project.

Thx for your reply!
So far so good... Now I get a permission denied when I call the getById-method.
I am wondering because I also see some 200 states, so..
By the way: If I call the "commands"-method, I can control my device...

Hello, the "1106 permission deny" indicates that you currently do not have the permission to call the API. Please check under the cloud development module of the IOT platform whether the corresponding cloud service has been opened, and that the opened cloud service has been authorized to the corresponding cloud project.
Please refer to the document：https://developer.tuya.com/en/docs/iot/ ... wsvmgoj3et

e.g The method "getById" may correspond to the "Industry Basic Service" cloud service
