Hello, I want to define a period of time (start date and end date) in only one card (easier to modify) like: **periodCard** : - start date: 8h00 - 17/10/18 - end date: 20h00 - 20/10/18 **firstDayPeriodCard** : - If motion sensor started then lights on **lastDayPeriodCard:** - If doorlock is locked, no motion for 3 hours then lights off **+1DayPeriodCard:** - If no motion for 10 hours then start cleaning At this point, I’ve got something like this (with the help of [Maikel](https://community.homey.app/u/Maikel)): ![19](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/6/6f81ae65f8bab4d8ce110cd79f850a95db95c2fc.jpeg) But I don’t know how to trigger things at the end and end +1 of this period ☹ Any ideas for me ? Have a nice evening ! Julien ---

Yes. > [@Julien\_Moors](#): > > I want to define a period of time (start date and end date) in only one card (easier to modify) Unpossible. U can make flows with the trigger “This flow is started”. Then u can make the flow like above and instead of “Enable a flow” u could use “Start a flow” Then u have ur trigger. ---

Hello ! Thank You for feedbak ! Is it possible to calculate thé différence between two dates (in seconds) and use this as a delay to start a flow ? (I don’t know if I’m clear enough) Enjoy your weekend ! Julien ---

3.5 days = 84 hours in seconds still 84 hours delay? What do you want to start delayed with 84h? Pls describe what you want to accomplish for a scenario not the way you thought but didn’t finish. Edit: your Period Card is a condition, either date between or time between, but not date&time between other date&time. if you use both cards it will have impact it wont run any night. If you want to enable / disable something over a long time you need two flows / two triggers each with a date/time one start to enable and one end to disable. or a schedule (2 x an alarm) or one of the 3rd party apps (maybe possible with Homedall? or… I don’t know.). The enable/disable can be a Tag or Virtual Switch. (HouseIsRented = true) Flow 1: Enable When Time (or an Alarm Start) , then HouseIsRented = true Flow 2: Enable When Time (or an Alarm Stop) , then HouseIsRented = False, Other Flow: When Motion detected, and HouseIsRented=True and between xxh - yyh, then Lights On and Start CountDown Light 3h and Start CountDown Cleaning 10h Other Flow: if CountDown Light = 0 and Door is Locked, Lights Out, (? Why 2h59 after locking the door? but Ok.) Other Flow if CountDown Light = 0 and HouseIsRented=False then Start Cleaning (this can trigger more often if there is motion, but add a counter to stop triggering if you want.) This last one will not trigger if there is last motion more than 10 h before end period. but you can fix that… ---

Hey Dijker, I’m searching the easiest way to start flows at the begining of a period, start flows at the end of that period and start flows at the end of the period + 1 day 🙂 thank you, Julien ---

Flows don’t run continuously, they start on an event. That could be a change in a value (fe Temperature, energy, light), an alarm (Motion, fire, a set Alarm Time/Day) or an other state change (Presence) or at a certain time (a date, a time each day, sun up/down, every xx seconds/minutes/hours…) There is no easy way to put your request in one flow at the moment. The only way to trigger from the start of one flow on a 2nd and 3rd time is to start something (fe Countdown) that creates new events (CountDown Timer reaches 0 ) where other flows trigger on. ---

Thank you a lot for information Dijker ! ![07](https://us1.discourse-cdn.com/flex025/uploads/athom/original/2X/3/321082c0c0a2fa9419dcaf63dde69dfa57ecc765.png) I’ve done something like that and I’ve just to change ‘Date check-in’ and ‘Date check-out’ 🙂 Maybe I’ll find a solution to trigger whit iCal directly ! Have a nice weekend, Julien
