Bash script for sending snapshots using Telegram [Solved]

[MeneerKlaas]

Hi all,

Unfortunately there is not yet a function available in dzVents for sending a camera snapshot using Telegram.
I made some minor changes to a Bash scripts found in topic Motion detector with ESP8266 and HC-SR501.

Code: Select all

#!/bin/sh
# $1 = Chat ID
# $2 = Caption
# $3 = Disable Notification (true or false)
TelegramToken="12345678:AABBCCDDEEFFasdfjasdhfkashdf"
SnapFile="/var/tmp/camsnapshot.jpg"
# Get snapshot via Domoticz server
wget -O $SnapFile "http://192.168.123.100:8080/camsnapshot.jpg?idx=1"
# Send Telegram message with image
curl -s -X POST "https://api.telegram.org/bot$TelegramToken/sendPhoto" -F chat_id=$1 -F caption="$2" -F disable_notification=$3 -F photo="@$SnapFile"
# Remove SnapFile
/bin/rm $SnapFile

I have called the Bash file "telegram_snapshot.sh" and placed it in the /home/pi/domoticz/scripts/ directory.

Parameters:
1. Chat ID
2. Caption (Text shown under the snapshot send)
3. Disabled Notification (when true, the notification is silent)

In my dzVents script I added the line:

Code: Select all

os.execute('bash /home/pi/domoticz/scripts/telegram_snapshot.sh "-12345678" "Camera Snapshot" false  &>/dev/null &')

The addition of ''&>/dev/null &' will make sure the script is run in the background. Initially you may remove this part for trouble shooting.
