We are working on this. Currently since program settings do not have a concept of ‘stop time’, our work-around is to allow the ‘duration’ to be the time between sunset to sunrise. This should satisfy the immediate need to use OpenSprinkler for switching lights (from sunset to sunrise). The change should be included in the next firmware numbered 2.1.4. Thanks.
Ray, if I understand you correctly, the next update will allow for the ‘duration’ to be the time between sunrise and sunset (or vice versa), but not a specific time of the day? If so, I think I there are many users who would like to have a specific stop time implemented, eg turn lights on at sunset and off at 11:00pm every night. I personally don’t want my backyard lights on all night while sleeping. If this is already the case with the new update then please forgive me for this wasted post.
Thank you as always for your hard work on this project, it is truly enjoyable seeing OpenSprinkler grow and evolve.
