Help - Alarm System and Rules

[iz8mbw]

Hi all.
I'm thinking to create a house Alarm System with ESPEasy.
For now I have a PIR sensor connected to GPIO-12 as "Switch input - Switch" and it works as expected, so when motion is detected the GPIO-12 is High and I also send the detection via MQTT, all ok it works.

I would like to trigger an alarm siren when motion is detected, so I'm thinking to use another GPIO (GPIO-16) to use as signal to send to the alarm siren.

So my idea is:
When motion is detected (so GPIO-12 High) set to High the GPIO-16 for 30 seconds also if in these 30 seconds the motion is not more detected (so also if GPIO-12 go to Low). In other words I want to hear to the siren for 30 seconds when motion is detected and also if the detection is for only 3 seconds.
Then, when motion is not more detected (so GPIO-12 Low), stop the alarm siren (so GPIO-16 got to Low).
If, after 30 seconds or more, another motion is detected (or detection is still in progress) the alarm siren should still make sound.
Use this behavior forever.


I have created this Rule:

Code: Select all

on motion#Detection=1 do
  GPIO,16,1
  TimerSet,1,20
Endon

On Rules#Timer=1 do
   GPIO,16,0
  endif
 endon

this Rule works well but only if the detection time is less than 30 seconds.

Many thanks for help.

Code: Select all

On Rules#Timer=1 do
   GPIO,16,0
  endif
 endon
 

There is only an "endif", not an "if".

Also, what platform are you using? ESP32 or ESP8266?
If it is ESP32, please use another GPIO for the PIR sensor as GPIO-12 on ESP32 is a big no-no to use as input which might be in a specific state during boot as it determines the voltage of the flash chip.

Using ESP32.
Ok, I'll go to change GPIO.
Sorry I wrong to copy/paste the Rule, this is the Rule I set:

Code: Select all

on motion#Detection=1 do
  GPIO,16,1
  TimerSet,1,30
Endon

On Rules#Timer=1 do  //When Timer1 expires, do
   GPIO,16,0
   Endon

Thanks.

Code: Select all

on motion#Detection do
  if %eventvalue1%=1
    GPIO,16,1
    if [int#1]=0
      TimerSet,1,20
      let,1,1
    endif
  endif
Endon

On Rules#Timer=1 do
   GPIO,16,0
   let,1,0
endon

Thanks!!!
Will got to test.

Hi.
The Rule you created works but the as you can see from this log (MQTT), the alarm siren (GPIO-16) starts just after the detection (and it's correct) but at 15:00:49 it stop also if at 2023-04-14 15:00:44 there was another detection.
The detection that started at 15:00:44 ended at 15:00:58 but the alarm siren stop at 15:00:49 (so before the end of detection).

Code: Select all

[2023-04-14 15:00:19] espeasy/motion/Detection 1
[2023-04-14 15:00:19] espeasy/control/Alarm 1
[2023-04-14 15:00:27] espeasy/motion/Detection 0
[2023-04-14 15:00:44] espeasy/motion/Detection 1
[2023-04-14 15:00:49] espeasy/control/Alarm 0
[2023-04-14 15:00:58] espeasy/motion/Detection 0

So it looks like the Alarm start for 30 seconds and it's not able to see the detection status during its alarm (so during the "TimerSet").

Looks like that can be solved by restarting the timer when a new detection is triggered:

Code: Select all

on motion#Detection do
  if %eventvalue1%=1
    GPIO,16,1
    if [int#1]=0
      let,1,1
    endif
    TimerSet,1,20
  endif
Endon
