But since we have a few more details now than in the original post, I might try two three things:
- Just open the Basic Rule you created and hit Done to re-initalize things (note that this will cancel the wait--i.e., it won't turn off at 10 PM until it starts over again, which looks like sunset-30 for you, so maybe wait until sometime that isn't between these two times if you want to test the 10 PM thing).
- Check the App Status (gear icon) page, particularly the "Event Subscriptions" and "Scheduled Jobs" sectoion. In your case, it looks like you should see a scheduled job for either sunset-30 or 10 PM, depending on when you look.
- Make sure your time and location (which are used to calculate sun times) are correct in Settings > Hub Details.
