In the official setup instructions I see the steps for esp8266. But when I perform the said steps I'm running into some issues. I see a few people have [built some devices](https://community.smartthings.com/t/esp8266-cannot-be-added-in-smartthings-app-device-not-supported/188637) with esp8266 and SmartThings direct connected devices. In wayback machine also I see this was a different repository https://web.archive.org/web/20220322012941/https://github.com/SmartThingsCommunity/st-device-sdk-c-ref Why was this repository purged?
