Is there a maximum number of devices that can be returned by discoveryRequest?

Developer Programs Support

I am using cloud connected devices,
For these two interfaces:, interactionType:
discoveryRequest + stateRefreshRequest
Document: Interaction Types | Developer Documentation | SmartThings

My interfaces all respond to parameters normally, but the smartings app will prompt that something is wrong,
I found a feature:
When I have a small number of devices, there is no problem;
When the number of devices is large, there will be problems (90);
The interface time consumption is also normally within 500ms;

Questions:

  1. Is there a limit on the number of devices?
  2. Is there a limit on the interface response time? What is the default time limit now?
  3. Where can I adjust the interface response time to make it larger?

Hi, @wunan_li

So, do you mean that you tried to discover 90 devices in a single Schema connector? Are you getting a specific error when it fails?

Also, by “interface response time” are you referring to the time it takes after you log in to the third-party cloud to send all the discovery and state refresh interactions?

  1. The smartthings app only says something’s wrong, but my backend server does not receive the task error callback information (interactionResult)

  2. How much time do discovery and state refresh take individually or together?

Hi, @wunan_li

I asked the engineering team, and discovering 11 devices shouldn’t cause an issue per se, so we need more information to investigate what happened. To do so, we need the following:

  1. App ID of your Schema connector. (The one that starts with “viper_…”)
  2. Replicate the issue and:
    • record your screen to have a better reference for which part of the process fails and hare the video with us
    • get the app logs:
