Run script once on door sensor

[jon205]

I have a script that sends a snapshot of my IP-camera to my phone through telegram. I've placed a door sensor in my letterbox and linked the script to the sensor in Domoticz. This works fine, but... The script should only run once when the letterbox is being opened. In stead of donig that, it starts the script again, the entire duration of the 'door' being open. So I get like 3 or 4 pictures on every 'opening'. What can I do to let it run the script only once?

Thanks, Jon.

First of all, publish your script (between code tags). It's a wild guess what is happening now and what to do to prevent this behaviour

I use this script for my doorbell as well. When the doorbell is being rung, it runs this script once. I think it's not the script, but the script is being triggered more than once.
I'll have to look up the script when I'm at home.

Code: Select all

SnapFile="web.jpg"

# Get snapshot via Domoticz server
sudo wget $SnapFile "192.168.*.*/cgi-bin/getsnapshot.cgi"
sudo cp getsnapshot.cgi web.jpg
# Send Telegram message with image
curl -s -X POST "https://api.telegram.org/bot***:AAH-6AvLY2HnubxTujFVs**/sendMessage?chat_id=***/sendMessage?chat_id=***&text=Post!"
curl -s -X POST "https://api.telegram.org/bot****:AAH-6AvLY2HnubxTujFVsS**/sendPhoto" -F chat_id=*** -F photo="@$SnapFile"
# Remove Image
sudo rm $SnapFile
sudo rm getsnapshot.cgi

This is it.

Assuming your script is triggered multiple times because domoticz receives multiple open signals you can prevent the snapshots from being send shortly after each other by pasting the script-snippet below, before the body of your script.

Code: Select all

#!/bin/bash

 minimumTimeBetweenSnapshots=30             # seconds
 thisFile="$( cd "$(dirname "$0")" ; pwd -P )"/${0##*/}     
 thisFileWithoutExtension=${thisFile%.*}
 lastTimeStartedLog=$thisFileWithoutExtension"_lastTimeStarted.data"
 
 #-- begin debugLines
 echo thisFile                :  $thisFile
 echo thisFileWithoutExtension:  $thisFileWithoutExtension
 echo lastTimeStartedLog      :  $lastTimeStartedLog
#-- end debugLines
 
 now=$(date "+%s") 
 if [  -f $lastTimeStartedLog ] ; then
     lastTime=$(cat $lastTimeStartedLog)
     secondsAgo=$(($now - $lastTime))
	 # echo $secondsAgo
	 if [[ $secondsAgo -lt $minimumTimeBetweenSnapshots ]] ; then
		# Too soon after previous execution exiting now
		exit 1
	fi	
 fi
 echo $now > $lastTimeStartedLog
 
 
 #
 # Body of your script to follow below

I'll try this when spare time > 0
Thanks for sharing.
