Got my USB webcam sending an image whenever my PIR is tripped...
Bash script... saved as cam.sh inside dtgbot folder
Code: Select all
#!/bin/bash
fswebcam -r 1280x720 /var/tmp/image.jpg
Domotics LUA script...
Code: Select all
commandArray = {}
if (devicechanged['PIR'] == 'On') then
os.execute('/home/pi/dtgbot/cam.sh')
os.execute('curl -s -X POST "https://api.telegram.org/botTOKEN/sendPhoto" -F chat_id=YOURCHATID -F photo="@/var/tmp/image.jpg"')
end
return commandArray
I will add an alarm switch aswell so as to only capture image when alarm on and motion detected.

Did you see the script I made to send a collage of multiple pictures taken at an interval with Telegram for this purpose?
EDIT: Found it.... just adapt it to your needs. This one can send it to 2 different Telegram ID's:
Code: Select all
#!/bin/sh
token="Put here your BOT token without bot prefix"
SendMsgToPerson1="Telegram id person 1"
SendMsgToPerson2="Telegram id person 2"
pausebetween=1
DomoUrl="127.0.0.1:8080"
SnapFile1="/tmp/1.jpg"
SnapFile2="/tmp/2.jpg"
SnapFile3="/tmp/3.jpg"
# get first Picture
wget -O $SnapFile1 $DomoUrl"/camsnapshot.jpg?idx=3"
FTime1=`/bin/date '+%H:%M:%S'`;
sleep $pausebetween
# get second Picture
wget -O $SnapFile2 $DomoUrl"/camsnapshot.jpg?idx=3"
FTime2=`/bin/date '+%H:%M:%S'`;
sleep $pausebetween
# get second Picture
wget -O $SnapFile3 $DomoUrl"/camsnapshot.jpg?idx=3"
FTime3=`/bin/date '+%H:%M:%S'`;

This was going to be my next step or research. Thanks for this.
This command however does not work with my USB webcam. I have tried several different syntaxes from google search.
wget -O $SnapFile3 $DomoUrl"/camsnapshot.jpg?idx=3"
But luckily I do have a workaround to get the snapshot.

My example script retrieves the snapshot from domoticz, not the cam directly, so it could be you need to change the domoticz url to includes https and/or userid/password.

I read somewhere that other people also did not get the snapshot from a USB camera. Some got all green snapshot.
Also that the image url should display the image inside the browser and not be downloaded. Mine downloads everytime.

I got your script working 100% to one person. Only have one telegram account in the house now.
Code: Select all
#!/bin/sh
token="XXXXXXXXXX:xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
SendMsgToPerson1="xxxxxxxxxx"
pausebetween=1
SnapFile1="/var/tmp1/image1.jpg"
SnapFile2="/var/tmp1/image2.jpg"
SnapFile3="/var/tmp1/image3.jpg"
# get first Picture
fswebcam -r 640x480 /var/tmp1/image1.jpg
sleep $pausebetween
# get second Picture
fswebcam -r 640x480 /var/tmp1/image2.jpg
sleep $pausebetween
# get second Picture
fswebcam -r 640x480 /var/tmp1/image3.jpg
## ---- Telegram -------------------------------------------------------------------------
# Send to Telegram
curl -s \
-X POST "https://api.telegram.org/bot"$token"/sendMediaGroup" \
-F chat_id=$SendMsgToPerson1 \
-F media='[{"type":"photo","media":"attach://photo_1"},{"type":"photo","media":"attach://photo_2"},{"type":"photo","media":"attach://photo_3"}]' \
-F photo_1="@$SnapFile1" \
-F photo_2="@$SnapFile2" \
-F photo_3="@$SnapFile3"
# remove Pictures
rm $SnapFile1
rm $SnapFile2
rm $SnapFile3
Need to convince my wife to get telegram so she can also get snapshot updates.

SO arming my system and sending snapshots whenever the PIR gets triggered worked, but I get snapshots every 10 seconds while the motion continues.
I made these modifications to prevent further sending of snapshots for the next 5 minutes...
Seems to be working fine.
Code: Select all
commandArray = {}
if (devicechanged['PIR TV Room'] == 'On' and (uservariables['Send_Once'] == 'Off')) then
os.execute('/home/pi/dtgbot/cam_collage.sh &')
commandArray['Variable:Send_Once'] = "On"
commandArray['Variable:Send_Once_RESET'] = "Off"
end
if (devicechanged['PIR TV Room'] == 'Off' and (uservariables['Send_Once_RESET'] == 'Off')) then
commandArray['Variable:Send_Once_RESET'] = "On"
commandArray['Variable:Send_Once'] = 'Off AFTER 300'
end
return commandArray
