Group:Switch gPresent "Present group" <present>
is also not triggering the rule. I wonder if the following is required
Group:Switch:OR(ON,OFF) gPresent "Present group" <present>
Group:Switch gPresent "Present group" <present>
is also not triggering the rule. I wonder if the following is required
Group:Switch:OR(ON,OFF) gPresent "Present group" <present>
I have updated the above code that I payed above which you can find here:
My understanding is adding a type to the group should be sufficient to get update events on the Group but since I use gPresent’s state elsewhere I’ve always had a function.
I noticed that there is no ReentrantLock in the new code. Is that not required anymore?
That is correct. The ReentrantLock is no longer needed. I’ve been running this code for many months now and I honestly don’t remember why there ReentrantLock lock was in there in the first place.
I have a DateTime associated to each Sensor as Rich Koshak as explained in another post.
i want to display the max of all those dates
How can i proceed ?
Group:DateTime:MAX SensorUpdates
Something like that should work.
If not you will need a Rule and a Proxy Item.
@rlkoshak Thanks i will try but i have seen another issue
The Sensor_lastUpdate is update at each reboot or restart service
Rule:
rule "ZWaveNode2_DoorWindowSensor"
when
Item ZWaveNode2_DoorWindowSensor changed
then
ZWaveNode2_DoorWindowSensor_LastUpdate.postUpdate(new DateTimeType())
end
log at the boot
018-06-06 10:06:42.821 [vent.ItemStateChangedEvent] - ZWaveNode2_DoorWindowSensor_LastUpdate changed from NULL to 2018-06-06T09:41:32.001+0300
influxdb.persist:
Strategies{
everyMinute : "0 * * * * ?"
every5Minutes : "0 */5 * * * ?"
everyHour : "0 0 * * * ?"
everyDay : "0 0 0 * * ?"
default = everyChange
}
Items{
* : strategy = everyChange, everyDay, restoreOnStartup
}
i have tried to check if the value is not NULL in my rule (boot time) but it do not work
rule "ZWaveNode2_DoorWindowSensor"
when
Item ZWaveNode2_DoorWindowSensor changed
then
if (ZWaveNode2_DoorWindowSensor.previousState().state.toString!==NULL){
ZWaveNode2_DoorWindowSensor_LastUpdate.postUpdate(new DateTimeType())
}
end
it do not work
Could you advise?
Try that.
Don’t forget the ;
after return
rule "ZWaveNode2_DoorWindowSensor"
when
Item ZWaveNode2_DoorWindowSensor changed
then
if (previousState === null) return; # Don't run the rule if the previous state is null
ZWaveNode2_DoorWindowSensor_LastUpdate.postUpdate(new DateTimeType())
end
Use
if(previousState != NULL) {
.previousState will give you the most recent value in the database. So what is probably happening is the changed state (i.e. the change that triggered the Rule) is already saved in the DB before the Rule executes giving you the current state of the Item when you call previousState. This is why the implicit variable previousState exists.
Also, only use !== or === when on of the operands is null
which is not the same thing as NULL
.
THanks a lot
Thanks
The return is like an "Exit rule " or “exit if”?
Exit rule
Hi Rich
In your pattern you have an item Garage_status_LastUpdate which shows when the garage was opened, it records a value like so:
smarthome:status Garage_status_LastUpdate
2019-02-24T20:09:00.539+1100

Am I right in saying a Transform map could somehow conver this rather unusable string to something more like minutes or seconds that the door has been open for use in an TTS Alexa rule?
Regards
No. That item is a DateTime so it records an instant in time, not a duration.
You need a Number Item and a Rule to periodically increment the value while the door is open. Then you need a JS transform to convert the number, let’s say minutes, to hh:mm
Hello,
Where can I learn how to have my openHab raspberry PI home hub detect when a remote raspberry PI that detects my cell phone via Bluetooth for presence detection?
Mike
https://github.com/rkoshak/sensor Reporter is one way.
Integrating reelyActive on a Raspberry Pi 3 with openHAB over MQTT is another.
Thank you, I’ll dig in!
Mike
