I would also like to see a feature that would allow a program to start and end at a time related to sunrise or sunset. Start time is already implemented and works great. I understand that the data structure uses ‘duration’ and not an ‘end time’ per se, but it would truly add great functionality to the system. It would be great if the end time could be specified not only in relation to sunrise/sunset, but also a particular time of the day.
I forked Dan’s python program and wrote a plugin to achieve this functionality, but it is becoming a bear to update my fork and merge with the original. I appreciate your effort it making this a feature in the unified firmware!
