Direct Connection using RPI?

[nayelyz (SmartThings Developer Support)]

Hi, @lisxin. Welcome to the SmartThings Community!
I just saw your post was stuck. Are you still having this issue with the Direct-Connected integration?
Here’s another thread that could help you out:

Trouble with registering a device

Yes, sorry for the delay, I was checking some details with the internal team. SmartThings doesn’t have an official release that supports RPi, so, we’re not sure from where you got the version you mentioned: Regarding the error, are you (by any chance) using an old direct-connected project and registering new test devices? The team checked your onboarding config and suggested you download the onboarding_config.json file again: You would get a new SSD like Pool Controll_E40A4b0016lWmmiim5 instead of Pool_Controll_E40A4b0016lWmmiim5 (underscore in the middle of the name) Use that new onboarding file in your device.
