when Item Lum_Sensor changed AND “get.timeofday > 18”

No that would not work. Rule triggers are event based, not state based so it makes no sense to use AND in a rule trigger. Those two events will never occur at the same time (note the event for “get.timeofday > 18” would only occur one second after 17:59).

See this posting for how I handle this.

Automation/Orchestration Design Patterns

RLK back with another Design Pattern to add to the list. Time Of Day Triggers The Problem: Many of us have rules that we want to only execute or behave differently during certain time periods of the day. As our rules grow there is the potential that more and more parts of the system will need to have this capability (e.g. lighting, HVAC, blinds, etc). Sometimes the times that define a period are fixed (e.g. 11pm) and others they are based on celestial events (e.g. sunset). This can result in …

The tl;dr of it is I have a String Item that gets set to a string representing the current time of day (Morning, Day, Evening, Night) and rules that change this Item based on times and/or Astro events. For example, Evening starts 90 minutes before sunset as calculated by Astro and ends at 11:00 pm.

In the rest of my rules, when I need to do something at the time of day change I trigger on updates to my TimeOfDay Item. In other rules that care about what the time of day is to determine behavior (e.g. you only want to run your logic during one period of day) I check to see if the TimeOfDay is currently set to the right time.

So, assuming you implemented my rule like this your rule would become:

rule "LivingLightOnWhenDark"
when
    Item Lum_Sensor changed
then
    if(TimeOfDay.state.toString == "Evening") {
        if(Lum_Sensor.state < 500 && Lum_Sensor.state > 300){
            logInfo("Staanlamp", "Auto On") 
            sendCommand(Staanlamp, 50)
        }
    }
end

If you think your system will eventually grow into needing other rules that care about the time of day I highly recommend this approach. However, if you think you will only ever care about evening in this one rule, your rule would look like this (assuming your evening starts at 7:00 pm and ends at 10:00 pm:

rule "LivingLightOnWhenDark"
when
    Item Lum_Sensor changed
then
    val eveningStart = now.withTimeAtStartOfDay.plusHours(19).millis
    val eveningEnd = now.withTimeAtStartOfDay.plusHours(22).millis
    if(now.millis > eveningStart && now.millis < eveningEnd) {
        if(Lum_Sensor.state < 500 && Lum_Sensor.state > 300){
            logInfo("Staanlamp", "Auto On") 
            sendCommand(Staanlamp, 50)
        }
    }
end
