@Urknall78, it should not matter if you use Smart-life or Tuya app. Both should working. I use Smart-life myself and @Peter_Kawa has best results with Tuya app. Switching app sometimes helps because people are mixing credentials, the same for restting the passwords.
@Philip_Montgomery, Most important is that you follow the instructions and if you have an error, look at the eror codes and the FAQ in first post, this skill id is described with solution, just read.
