Custom Time schedule in Sitemap

Hello Community,

is it possible to create custom time schedules within a Sitemap?

I want to implement my watering system (exist out of Shelly Unis) into Openhab and want to schedule a timeframe for the watering.


  • Start Time
  • End Time


  • Start Time
  • Watering Time (in Minutes)

The Shelly integration is no Problem, but I’m not sure if I can implement time schedules within a Sitemap.

Thank you very much!

Short answer: No.

Long answer: Yes. But… :wink:

There is no direct option to do, because there aren’t any Widgets to set time via Sitemap. Create some Items (start_hour, start_minute, stop_hour, stop_minute…) to set hours and minutes, then create a rule to calculate the command to send to the shelly. There are tons of rules here to do this.

But some general thoughts about: Do you need to set exact minute and hour? Maybe ten minute steps would be sufficient. Or maybe it would even suffice to set time in a more simple way, e.g. “time 1”, “time 2” and “time 3” (chose from a list of possible values).

Another option would be to use a calendar.

Or don’t do it by time at all, but by sun, rain, humidity and temperature (and weather forecast).

Hello Udo,

thank you for your quick answer.

For “normal” watering it is sufficient to have a rule for a scheduled time, thats right. I only asked because it would be more individual if i can set the start-time within the app directly.

I think i will implement then switches for start-times (hard coded within the rule), but it would be very nice if we have a extra field (or calendar) to set custom time schedules in future.

i solved my problem with String items and defined it within the sitemap as “selection”.

In the picture you can see the “selection” named as “Startzeit” and “Minuten”, as i need to configure the start-hour and start-minutes.

Rules for program start:

  • The rule checks if the program was already run today (item bew_timer_triggered)
  • The rule calculate out of the choosen hour and minutes and the actual time if the time passed to activate the program
  • the rule checks the rule checks if i want to run the program today and have a look if the “bew_timer_day” value is ON (how i calculate if the item is switched ON or OFF you can see above in the other rules)
  • the program start and checks for each watering-system, if i switched it ON and how long i want to have it ON.
