Sunrise And sunset

I just got a smartthings hub 14 days ago.

Do I have set a location for my hub to get sunset and sunrise rules to work appropriately?

I get to the “edit name” page of an automation rule in the smart lighting app and the rule fails to save if the rule is based on sunrise/sunset. If I use a specific time of day, the rule saves fine.


Yes, we don’t know what time the sun sets/rises if you don’t.

My location is configured and was working for months. Within the last couple of days all routines that are triggered by sunrise or sunset have not worked. Is this a known problem? If not, any idea of what I need to do to fix it?
