настроил правило:

в общем то все хорошо, калькулятор работает, правило тоже работает (включает и выключает свет и по времени и по восходу / закату, НО…
согласно правила свет выкл. в 23-59, и не должно вкл-я до 07-00, но свет включается в 00-00 и горит, пока не обновятся даты восхода и заката следующего дня… (на скрине обвел)…
вопрос к тем, кто ковырял данный код, где что посмотреть и подправить ??
лампочки пока не вешал, тестирую на диммере…бывает через час, а бывает через два часа данные обновляются и свет тухнет до назначенного времени…
