Hello,
many of uf first of later will try to implement a PIR based light for his home.
With openhab 3 enviromet rule engine is quite simple…
you decide the triggers elements, the conditions of trigghering and a very little script like the following to execute:
I would use expire binding on a textual item in OH2 and is included in OH 3 as a metadata variable
something like
expire=“200ms,command=OFF”
on an OH2 item
add as metadata in OH3 - click Add Metadata - choose expiration timer
This way once the time is up it will do the command eg off. If it is triggered again it starts the timer again.
This also gets round the numbers of timers you can have (2 in OH2 - no idea about in 3).
Timers have their uses but expire is better here.
Hello,
Ok, but is also possible to expire with timer only after certain hour of the day?
Maybe did not understand well the feature. If I add metadata expire to a switch it will switch off after some time right?
I know what you mean. I used this feature very often in OH2. I had a special switch for this. Example: Kids wake up in the night. Then I make ligth on for 30 minutes, all go to bed. OH will switch it off. But on the evening I don’t want it.
Exactly
Proliferation of “dummy switches” is not smart and efficient at all as rule management in my opinion.
I hope OH staff take in consider these big laks and will implement something in next release… My rule now is not the same as before without global and timer variable…
I’m trying from days to run a one with these method… no luck
I adapt getHourofDay to getHour but no luck and other adaptation/migration stuff find in the forum but the rule with globals var does not trigger at all
It is basically an energy monitor for may fotovoltaic + normal energy system.
timers it to prevent alexa trigget continously the High consumption warning.
//Global Varibles
var Timer Timer_Pow = null
rule "Energymonitor"
when
Item MQTTEnergymonitor_EnelPotenzaReale received update or
Item MQTTEnergymonitor_PannelliPotenzaReale received update
then
if (MQTTEnergymonitor_EnelPotenzaReale.state > 0 && MQTTEnergymonitor_PannelliPotenzaReale.state > 0)
{

if (MQTTEnergymonitor_EnelPotenzaReale.state >= 5000 && (now.getHour() >= 8 && now.getHour() < 24) && Timer_Pow === null) {
Timer_Pow = createTimer(now.plusSeconds(20)) [|
Alexa_Speak.sendCommand("WARNING . CONSUMPTION TO HIGH.")
Timer_Pow.cancel
Timer_Pow = null
]
}
end
if copy paste, nether the first data update part, before alexa speack if, is executed
after many and many try on spare script I found what do not work.
I dont know why but sometimes the item.state value must decleared as Number.
here the first modified rule that seems to working.
I’m looking at the PIR exaple to fix it
//Global Varibles

end
Edit:
here the PIR exaple working for OH3
// Global Variables
var Timer Timer_PIR = null
rule "PIR Soggiorno"
when
Item MQTTESP_PirSoggiorno changed from OFF to ON or
Item MQTTESP_PirCucina changed from OFF to ON
then
if ((now.getHour > 20 || now.getHour < 7) && Timer_PIR === null && Scenario.state == 0 && MQTTESP_LuminositaSoggiorno.state < 5 && (Lifx_Brightness.state < 5 || LifxSoggiorno_Online.state == OFF) && (RGBWStrip_Power.state == OFF || RGBWStripCucina_Online.state == OFF) && (MQTTSonoff_LuceCucina.state == OFF || SonoffCucina_Online.state == OFF) && (MQTTSonoff_LuceSalotto.state == OFF || SonoffSoggiorno_Online.state == OFF))
{
sendCommand(RGBWStrip_Power, ON)
Timer_PIR = createTimer(now.plusSeconds(1)) [|
if (now.getHour > 20 && now.getHour < 23)
{
RGBWStrip_Color.sendCommand("200,30,90")
sendCommand(Lifx_Brightness, 25)
}
else if (now.getHour > 23 && now.getHour < 1)
{
RGBWStrip_Color.sendCommand("50,30,50")
sendCommand(Lifx_Brightness, 15)
}
else if (now.getHour > 1 && now.getHour < 7)
{
RGBWStrip_Color.sendCommand("50,30,20")
sendCommand(Lifx_Brightness, 10)
}
]
Timer_PIR = createTimer(now.plusSeconds(180)) [|
Timer_PIR.cancel
Timer_PIR = null
sendCommand(Lifx_Brightness, OFF)
sendCommand(RGBWStrip_Power, OFF)
]
}
else if (Timer_PIR !== null) {
Timer_PIR.reschedule(now.plusSeconds(300))
}
end
OH3 has an “expiration timer” metadata element in the items. You can set the timeout for your light there. Everytime the item is send the ON command from the PIR or motion sensor, the timer will reset.
I had a scenario, where I want to be able to switch the lights on without triggering the timer. So I created a virtual on/off switch item with the timer. My motion sensor triggers this virtual switch instead.
I have then created rules, that tell my light to be switched on (and off), when my virtual switch is switched on (and off).
Hi all,
we would like to share with community our solution for HC-SR501 PIR sensor to control light for OpenHAB 3. It is usable with any other PIR sensors. You can activate/deactivate light controlling with button and also change a timer as you want. Rescheduling works as expected. In case of Away Home we get a motion notification from each zone by email or telegram push.
