I use sunrise time value to control morning lights along with outdoor Lux. I thought I took the value from the OpenWeatherMap driver. In truth, I actually had to review a couple rules to find out where I was pulling it from and found I was taking it from the Hub
I was up early this AM (for me on a weekend day anyways) and my dashboard said Sunrise was at 6:11a but the rules didn't trigger. I started to look at the logs and bang they triggered. 2 minutes later.
In my Hub settings, the Sunrise value is/was 6:13a.
I checked the google and verified from 2 sources that sunrise was at 6:11 (technically 6:10:10a). Tomorrows sunrise is 2 minutes earlier. Yesterdays Sunrise was 2 minutes later.
I suspect there is a time related issue with the Sunrise value reflecting the previous days sunrise time or not updating itself at a time when it is most useful.
My solve was to fix my rules to use the OWM value. In the end, I actually just dumped the 2 rules in favor of just pure lux. No doubt a nitpick, but this could be important to others in the HE world to be checked out.
Here's a snap of one rule (you can see (6:13a):
And my dashboard with OWM:
