I’m trying to follow steps here Tuya - Home Assistant but i end up with error “API产品开通失败” when I try to ADD IOT Core API. If I dig in chrome network traffic I find this error “errorCode”:“API_PROJECT_OPEN_FAILED”
I am pretty new at ha so sorry not sure about the error, but i can confirm it is working fine for me.
did you end up fixing this? im having the same issue
