Can't attach static image from webcam to telegram using Dlink DCS-935L

Configuration
1

Hi,

I got lucky today at my local Staples and snagged two Dlink DCS-935L IP Cameras. I have them up and running, and I can see them in HA with a static image that is changed every 10 seconds using the generic MJPEG stream. I am now trying to add Telegram in, as one of the webcams I have in my porch and would like it to send a message/picture when my doorbell is pressed. I have the automation working, and can successfully send a text only notification with Telegram and syncs to my devices. But, when I try to add the photo, I get this error in my HA log:

16-09-10 19:35:23 homeassistant.core: BusHandler:Exception doing job

This is my lines in automation.yaml

- alias: 'Back Door Notify'
  trigger:
      platform: state
      entity_id: binary_sensor.2_door_chime_sensor_2_1
      state: 'on'
  action:
    service: notify.webcam_telegram
    data:
      message: "Someone is at the back door!"
      title: "Home Assistant"
      data:
        photo:
          - url: http://192.168.86.130/image/jpeg.cgi
            username: xxxxxx
            password: xxxxxx

Does anyone have any idea what I am doing wrong, or canā€™t I parse the URL to get the snapshot?

Thanks,

Finally Iā€™m able to help somebody! I made this yesterday. I doesnā€™t win any prizes, but it does the job. The next thing I want to do is create 5 pics, 1 second apart and telegram it. Should be easy with copy/paste but that not very elegant.

cfg/shell_commands.yaml
take_pic: curl -o /home/hass/snapshot.jpg -A cgi http://admin:[email protected]/image/jpeg.cgi

cfg/automation/test_telegram.yaml:

  • alias: ā€˜Test Telegramā€™
    trigger:
    • platform: state
      entity_id: input_boolean.test_telegram
      to: ā€˜onā€™
      action:
    • service: shell_command.take_pic
    • delay 00:00:10
    • service: notify.telegram
      data:
      title: Send
      message: Send Image
      data:
      photo:
      - file: /home/hass/snapshot.jpg

Hi @jilsx

Thank you for your help. I was able to get it to work wonderfully with my camera. I ended up for ease of use placing the shell_command right into my configuration.yaml file for now, but it works. Telegram seems to be sending me the message about 10 minutes later for some reason though; iā€™ll have to look into that.

I was able to get the automation to work with with this:

- alias: 'Back Door'
  trigger:
      platform: state
      entity_id: binary_sensor.2_door_chime_sensor_2_1
      state: 'on'
  action:
    - service: shell_command.take_pic_porch
    - delay: 0:02
    - service: notify.webcam_telegram
      data:
        title: Home Assistant
        message: Someone is at the back door!
        data:
          photo:
            - file: /home/hass/.homeassistant/snapshots/snapshot_porch.jpg
              caption: Back Porch Doorcam

Did you ever get your consecutive telegramā€™ed pictures working? I was thinking of doing the same thing and linking it to a motion sensor and automation rule.

Iā€™ve ended up with the following:

  • Send 1 pic via telegram
  • Send 10 pics (on second apart) via mail. I found this a little more elegant (to use my prior words). Probably can do it with Telegram and HASS alone, but Iā€™m already spending way to much time figuring out how that would work. Still getting used to the syntax.

The shell command Iā€™m using is:

#!/bin/bash

month=$(date +"%m")
day=$(date +"%d")

hour=$(date +"%H")
minute=$(date +"%M")
second=$(date +"%S")

folder=/mnt/sda/hass/camera1/$day$month-$hour$minute$second

mkdir -p ā€œ$folderā€

for num in {1ā€¦10}
do
curl -o $folder/$num.jpeg -A cgi http://admin:[email protected]/image/jpeg.cgi
sleep 1
done

mutt -s ā€œMotion Detectedā€ [email protected] -a $folder/*.jpeg < /tmp/mailmessage.txt

Just an update. Still havenā€™t figured out why there is such a huge delay between when the doorbell is pressed and the picture is taken and when I get the message. One thing I did do though that seems to ā€œspeedā€ up the process a bit is I have my automation set to send me a text notification of someone at the door, and then a second one for the picture. The text one comes in instantly and the photo about a minute later.
