I want to use a defined time item to trigger a rule. I know that this is possible with OH3. I am looking for a way to simply update this time item via Basic UI. I also found out that this is not possible.
My idea is to have 2 items in Basic UI for hour and minute. Every change will trigger a rule to update a time item in the backend and this timeitem will trigger another rule.
The question is now if I have 2 number items (hour, minute) how can I update a time item with their values?
I have read multiple threads but find no fitting solution.
Thanks for quick response but maybe there is some misunderstanding on my side. I have implemented one test rule:
rule "Wecker Uhrzeit"
when
// Wenn sich Minute oder Stunde ändert
Item virt_wecker_minute changed or
Item virt_wecker_stunde changed
then
val new_time = LocalTime.of(virt_wecker_stunde.state.to_i, virt_wecker_minute.state.to_i)
virt_wecker_uhrzeit.update(new_time.to_zoned_date_time)
end
But then I get the following error in the log after executing:
No resource methods have been found for resource class javax.ws.rs.core.Response
In RulesDSL, as I said, you need to do a circus of type casting. Try this
val hour = (virt_wecker_stunde.state as Number).intValue
val min = (virt_wecker_minute.state as Number).intValue
val new_time = LocalTime.of(hour, min)
val zdt = ZonedDateTime.now.with(new_time)
val datetime = new DateTimeType(zdt)
virt_wecker_uhrzeit.postUpdate(datetime)
rule "Wecker Uhrzeit" do
changed virt_wecker_minute, virt_wecker_stunde
run do
new_time = LocalTime.of(virt_wecker_stunde.state.to_i, virt_wecker_minute.state.to_i)
virt_wecker_uhrzeit.update(new_time.to_zoned_date_time)
end
end
By the way, Since openHAB 4, BasicUI now has an input element that lets you enter a date/time directly into a DateTimeItem
Ok - seems to work. But one thing I missed: my target is an item from “datetime” where hour and minute is updated correctly corresponding my 2 items - thanks.
But now this item is using the date from today with the entered hour+minute so if I try to use this item to fire a rule for a daily thing this won’t work.
Is there an option to have an item just with the time instead of the whole date? I think if the date is still in it I need another process to update it to the next day…
Ok - nice hint. But I am on OH3 at the moment. The last major update from v2 to v3 took several weeks that all of my automatization is running again so I will do this at a later point. Maybe the update from v3 to v4 is easier but last time it was many work for my environment.
Do you want the date to be 1 day from today? This will make it trigger just once, until you change the time again (which will re-set the date to 1 day from that time)
Do you just want to trigger on the time (ignore the date) every day?
Currently for setting the time item this is the rule:
rule "Wecker Pia Uhrzeit"
when
// Wenn sich Minute oder Stunde ändert
Item virt_wecker_pia_minute changed or
Item virt_wecker_pia_stunde changed
then
val hour = (virt_wecker_pia_stunde.state as Number).intValue
val min = (virt_wecker_pia_minute.state as Number).intValue
val new_time = LocalTime.of(hour, min)
val zdt = ZonedDateTime.now.with(new_time)
val datetime = new DateTimeType(zdt)
virt_wecker_pia_uhrzeit .postUpdate(datetime)
end
And then I’d like to use “virt_wecker_pia_uhrzeit” for firing another rule!
