Règles de bave utilisant l'expression de cron?

Question

J'ai une exigence que je veux tirer règle seulement pour les jours de la semaine.J'ai une certaine règle comme la fumée, la température, le mouvement.can vous me suggérez comment je peux faire la règle selon mon exigence.Please me donner un exemple.

Existe-t-il un meilleur moyen de déclencher des règles basées sur l'heure autre que cron?

Answer 1

Vous pouvez tirer la règle sur les jours de la semaine ou les week-ends, la même exigence que j'ai rencontrée, a trouvé une solution. vous venez pas en friche:

Note: Dans la méthode isExlude je mentionne 000000 signifie que la règle se déclenche tous les jours (000000 signifie S, M, T, W, T, F, Sat respectivly) et 0 signifie sur et 1 signifie hors
