So after a year of climbing the steep hill that is called ´learning how to use OpenHAB´, I finally am confident enough to share a piece of my smarthome with you. Disclaimer; I have/had no prior programming skills whatsoever, so if you have feedback as to how this rule can be improved code-wise that would be greatly appreciated! I tried to give as much info as needed, maybe overkilling it, but for me, info-rich threads really helped me to get the hang of OpenHAB. Hopefully this thread will do the same for other newcommers.
The rule below is used in my bedroom where the light is turned on when someone enters the room under certain conditions. The rule ´knows´ whom is entering, and turns on different lights depending in that person. Furthermore, if you only left the room for a midnight snack or toilet visit, OpenHab won´t turn on the light when you get back. For more side-information, read the Off topic part of this thread.
Off topic:
I live with my parents and am spending a lot of time in my bedroom, studying etc. When I come home, I want OpenHAB to ´know´ it is me that enters the bedroom so it can turn on the mood lighting. However, if my parents enter the room (bringing laundry etc.) and I am not home, they want a good amount of light, hence I turn on different lights depending on the one entering the bedroom.
At nights I put my phone in airplane mode. Via the Network binding, OpenHAB ´thinks´ I left the house which is not true. Thus, when I go to the toilet, OpenHAB turns on the ceiling light when I get back in my room, blinding me. Thanks to the second rule, the system ´knows´ I only left the room for a toilet visit (for example) and won´t turn on the ceiling light when I get back.
On-topic:
So this is the rule I have written with the help of a lot of people here on the forum:
var Timer motionTimer = null
var Number ToiletVisit = 0
rule "Bedroom Motionsensor"
when
Item MotionSensor changed to ON //Start the rule when motion is detected.
then
if(Sun.state != OFF) return; //As long as the sun is up, don´t execute.
if(User_Home.state == ON && Mood_Light.state == OFF) { //If you are home and the mood light is off
Mood_Light.sendCommand(ON) //Turn on the mood light.
} else if (User_Home.state == OFF && Mood_Light.state == OFF && Door.state == ON && ToiletVisit == 0) { //if you are from home, mood light is off the door opens and no one is visiting the toilet
if(motionTimer === null) { //execute al long as the timer is not set or running
Ceiling_Light.sendCommand(ON) //Turn on the ceiling light
Ceiling_Light_Bri.sendCommand(75) //Turn the brightness to 75
logInfo("Motiontimer", "started") //Notify that the timer has started
motionTimer = createTimer(now.plusSeconds(60), [ | //Create a timer for 60 seconds
var Home_Status = User_Home.state.toString //After 60 seconds, copy the state of User_Home to Home_status. If from home, it´s off. If home, it´s on.
Ceiling_Light.sendCommand(Home_Status) //Send the Home_status to the ceiling light.
motionTimer = null //change the timer to null so the rule can get triggered again if needed.
logInfo("Motiontimer", "done") //Notify that the timer is done.
])
} else { //If motion is detected while the timer was running
motionTimer.reschedule(now.plusSeconds(60)) //Drop the current timer and create a new one for another 60 seconds
logInfo("Motiontimer", "rescheduled") //notify about te rescheduled timer
}
}
rule "ToiletVisit value switch"
when
Item Door changed //if the door is opened or closed
then
if(Sun.state != OFF || MotionSensor.state != ON) return; //if the sun is up and/or there is no motion, don´t execute.
ToiletVisit = if(Door.state == ON) 1 else 0 // if above is true, change the value of ToiletVisit.
end
Hardware I used:
- Raspberry Pi 3B+
- Hue Motion Sensor
- Hue light bulbs
- Xiaomi Aqara door switch
- Bitron Funkstick
Bindings I used:
- Zigbee binding
- Network binding
- Astro binding
Hopefully this rule is something you could use.
Kind regards,

Edit: Spelling, removed reference to sleepwalking and improved the rule, according to feedback below.
