True false, also a good tip, but in my use case Id like to run one of 8 different “scene” flows for a room.

My attempt did work well the first time, but then I suddenly was not able to set a tag anymore. I did a restart. And now I run into the same problem described here:

The specific error I get is:

```auto
Cannot set value, token is not registered

```

Have you been using `await setTagValue`, and have you had trouble with it?
