I am not saying there isn’t an issue with sunrise and sunset scheduling, I’m just indicating it isn’t related to hub firmware or the hub itself. It may feel like an unnecessary detail but location, timezone, and Weather Station (which schedules sunrise/sunset) are cloud based and separate from the physical Hub.
If you look at the automations that aren’t triggering in the IDE, do Job History and Scheduled Jobs look correct? You should see a Scheduled Job matching the next sunset event.
Edit: We found the issue and it should resolve the automation executions for most if not all of you in this thread.
