1) By ‘dynamic’ I didn’t mean user-triggered dynamic events. I mean the scheduler works by dynamically arrange all programs / stations as they are encountered. It cannot be easily implemented as a static schedule like other controllers. As an example: OpenSprinkler allows multiple zones to run at the same time. Have you seen other sprinkler controllers that allow this? As one program runs, other programs / stations can start as well, and the scheduler will automatically handle them according to the sequential group flag. So what runs at the current moment is the result of a ‘dynamic’ set of programs / stations that started in the past.
With other controllers, since no two programs can run at the same time, it just scans through all programs, finds which one overlaps the current moment, and starts the program from there. It’s a lot simpler to implement. But this is not how OpenSprinkler works. Additionally, as I said, how far back do you have to start the scan? You could have a program that runs over multiple days. Is the firmware supposed to look back 7 days and check all programs that may start that far back and figure out maybe one of them would have run to the current moment?
Have you seen any other sprinkler controller that uses the concept of sequential group? Sure you may say you don’t run multiple zones at the same time, but many other users do. You may also say you don’t have programs that run over multiple days, but some other users do. If we implement a feature, we can’t do it in a way that work in some situations but not other situations. That would be an incomplete feature.
2) OpenSprinkler has a +5V terminal port, it can be used to power the controller. Find a 5V mini UPS and connect it between 5V and GND and that will keep it running. But it sounds like from your description that you must reboot the controller manually from time to time. I don’t know why, but if you have to do that, this solution won’t help you since it won’t prevent you from rebooting the controller manually.
3) Your example of the moon is super far fetched. If it was your application, you would need to find a NASA-approved equipment. Obviously OpenSprinkler is not NASA-approved, nor FDA-approved either. I can’t help if you need something so mission critical. That’s not our focus. I can’t help if your setup entails multiple reboots / power breaks on a daily basis. This is not our focus.
4) I will say this again: you are asking for something that we don’t have and don’t offer. So either implement it yourself, or find another product that works for you and move on. Spending time here complaining and being angry doesn’t help. It’s like you go to a restaurant and complain that the way they cooked lasagna is wrong. Well, you know that, that’s how they do it. If you don’t like it, go somewhere else and move on.
