Control LED strip by PIR sensor (with timer function?)

[Cheaps]

I'm busy with an ESP easy project in my bathroom. I have a small LED strip (powered by GPIO 5, 3.3 volt from the NodeMCU). I want the following result: If the PIR sensor is positive, I want to have the LED strip lit-up for 1 or 2 minutes. I use a PIR sensor without delay on it (self-delay is 2 seconds frome the PIR sensor itself)

I already tried a lot of things, but it's quite annoying to configure it well!

The current ESP easy configuration:


The current Domoticz configuration:



I already have tried to set the off delay in Domoticz on 120 seconds, but because my ESP easy already gives the off status at the same time as the on status is triggered, the LED is turning into a disco light!

I also tried to control it via a Domoticz event


And it also doesn't really work (becaus I entered the value of 20.000 in the URL to open, there is a quite 'long' delay, but it's not the 40 seconds. The logic of the 'wait' command doesn't really make sense.

I think this should be

Why using Domoticz fot this task?
Simply use rules on your ESPeasy.
It works then without Domoticz.

If PIR sensor triggers, set gpio pin for your LEDs on and set Timer1 to 120sec.
And On Timer1 event set gpio pin for your LEDs off.

Or if your PIR and LEDs are on different ESPEasys, send command directly between this units - again without Domoticz.
Instead PIR trigger in the example above use event trigger from incoming command.
And then you can report state of PIR and LED to Domoticz, if you need it.
Advantage - this way it will work even if Domoticz or your controller computer crashes.

What you actually want in this kind of setup is: When PIR sees movement light up the LED. When it hasn't seen movement for 90 sec, switch the LED off. Right?
I agree, this need to be done in rules, not Domoticz (its actually not possible). Activate rules under the advanced tab. Then write a rule with a timer. Setup the PIR as switch input, named PIR.

a rule for that will look something like that :

Code: Select all

On PIR#switch=1 do 
gpio,5,1
timerset,1,90
Endon

On Rules#Timer=1 do 
gpio,5,0
Endon

Thank you very much for your help! I'm not a hardcore programmer, so it's all quite difficult for me, sorry for that!
I tried to setup the rule with the same rule as you said above, and I see in the logging the following:



I see that the event is triggered, but I don't see the action (set GPIO 5 to 1, or to 1000, I've also tried that...)

Note: the PIR sensor is really quick in the off-state, so after 1 or 2 seconds it already give the status '0' .

I also tried only the above script

Code: Select all

On PIR#switch=1 do 
gpio,5,1
timerset,1,90
Endon

But it also doesn't give any results.


Edit: I finally got it, with the following code.

Code: Select all

On PIR#switch=1 do 
 PWM,5,1000,200
 timerset,1,90
Endon

On Rules#Timer=1 do 
PWM,5,0,200
Endon

The thing I forgot was the 'value' from device, to set it as 'switch' ! See the picture here:


Thanks everyone!

As you see in the log you have named both the device and value "PIR" so your rule should be :

Code: Select all

On PIR#PIR=1 do 
gpio,5,1
timerset,1,90
Endon

The log show all the events that is triggering.

Edit : you beat me to it!
