Hey, because this was todays top result from searching “openhab alarm clock” I would like to post my improved version. It it’s a mix of this and code from the android alarm-clock - version

Add your things to do in line 71 of the rule

items:

Number ALARM1_PERSON1_H    "Wecker Stunde [%s]"
Number ALARM1_PERSON1_M    "Wecker Minute [%s]"  
String ALARM1_PERSON1_D    "Wecker Wochentage"

Sitemap:

Frame label="Wecker" {        
     Selection item=ALARM1_PERSON1_D label="Tage" mappings=[0="  Aus  ", 1="  Mo - Fr  ", 2="  Sa - So  ", 3="  Alle Tage  "]`
     Setpoint item=ALARM1_PERSON1_H label="Stunde" minValue=0 maxValue=23 step=1
     Setpoint item=ALARM1_PERSON1_M label="Minuten" minValue=0 maxValue=55 step=5
}

Rule:

    } 
    val DayOfWeek[] theWorkDays = newArrayList(DayOfWeek.MONDAY,DayOfWeek.TUESDAY,DayOfWeek.WEDNESDAY,DayOfWeek.THURSDAY,DayOfWeek.FRIDAY)
    val DayOfWeek[] weekEndDays = newArrayList(DayOfWeek.SATURDAY,DayOfWeek.SUNDAY)

    var dayIsValid = false

    while (dayIsValid == false) {
        switch(ALARM1_PERSON1_D.state as Number) {
