temporally store image, for sending notification telegram [Solved]

[hoeby]

I want to send a camera snapshot by telegram.
The link for the camera snapshot is http://XXX.XXX.XXX.XXX/jpg/1/image.jpg
Unfortunally i can't get this type of camera added in domoticz. Therefor i was hoping to get 1 scripts for DZvents.

What i have is this. But i got stuck how i can temporally save a snapshot by dzvents.
Googled some and found some, but those scripts are way over my head to get the idea how they exactly work

Code: Select all

local camera1 = http://XXX.XXX.XXX.XXX/jpg/1/image.jpg

return {
    on = { 
       devices = {'Backlight Dashboard'},
    },

    execute = function(domoticz, device)
        if(device.state == 'On') then
          --os.execute('/home/pi/domoticz/scripts/snapshot.sh')
	   domoticz.log('Foto gemaakt en verstuurd', domoticz.LOG_INFO)
	   domoticz.notify('snapshot', camera1, domoticz.PRIORITY_HIGH)
        end
end
}

I have this script, which works.
But was hoping everything could be run by dzvents and not 2 scripts

Code: Select all

#!/bin/sh
SnapFile="/var/tmp/camsnapshot.jpg"
# Krijg snapshot van camera.
# Voer IP-adres in op XXX.XXX.XXX.XXX (houd rekening met user/password, dat script ook snapshot kan maken)
wget -O $SnapFile "http://XXX.XXX.XXX.XXX/jpg/1/image.jpg"
# Send Telegram message with image
curl -s -X POST "https://api.telegram.org/bot"DEZE TEKST VERVANGEN VOOR TELEGRAM API SLEUTEL"/sendPhoto" -F chat_id=DEZE TEKST VERVANGEN VOOR CHAT_ID -F photo="@$SnapFile"
# Remove Image
/bin/rm $SnapFile

Thanks Emme,
I got it working. Changed a few thinks and tested it in steps to see what happens (with domoticz.log)
And yes, it works.

Only need to test if it overwrites the made .jpg file. Or i need to delete the made .jpg file.
That's for later to test.

This is what i finished with

Code: Select all

return {
    on = { 
       devices = {'Backlight Dashboard'},
    },

    execute = function(domoticz, device)
        if(device.state == 'On') then
            local teleTok   = 'xxxxxxxxxxxxxxxxxxxxxx'
            local chatId    = 'xxxxxxxxxxxxxxxxxxxxxx'
            local snapFile  = '/home/pi/domoticz/scripts/camera_'
            local domoReq   = 'http://xxx.xxx.xxx.xxx/jpg/1/image.jpg'
            local camName   = 'Voordeur'
            os.execute('wget -O "'..snapFile..camName..'.jpg" "'..domoReq..'"')
            os.execute('curl -s -X POST "https://api.telegram.org/bot'..teleTok..'/sendPhoto?chat_id='..chatId..'" -F photo="@'..snapFile..camName..'.jpg"')
        end
    end
}

Added this code undernead the 2 other os.execute rows.
Be sure to add it undernead, otherwise the .jpg is deleted before it is sended with telegram

Code: Select all

os.execute("rm " ..snapFile..camName..'.jpg')

This removes the .jpg file. So i am sure that there are no problems with overwrite permisions.

Hi, can You explain how to set user/ and password.
I get the error 401 connection refused. Looks like it is used and password related.

Works perfectly, also with a username/password protected camera.

For some reason it keeps sending two same pictures

Can you switch on scriptlevel debug logging? It might reveal what is happening. Could it be that the script is triggered twice?

this script still works ?

Here is my way to send fotos from cams on motion detect.

But i'm on windows, so some code may not work.

Code: Select all

execute = function(domoticz, device)

	local tBot = '<your bot number>'
	local tChatId = '<your chat id>'
	    
	    local current_date_time = os.date("%Y-%m-%d_%H-%M-%S")

        local camera_url1 = '"http://<user>:<password>@192.168.0.36/webcapture.jpg?command=snap&amp;channel=1"' -- adress of camera snapshot
        
        local image_path1 = '"C:/Domoticz/screensfromcams/cam2floor/'.. current_date_time ..'.jpeg"' -- path to store snapshot
        
        local command1 = 'curl ' .. camera_url1 .. ' > ' ..image_path1  -- команда для выполнения 1
            
              
                os.execute(command1) -- saving snapshot to disk
                    
                --getting the name of last image in folder:
                local command1 = "dir /B /O-D /A:-D C:\\Domoticz\\screensfromcams\\cam2floor\\"
                local f = io.popen(command1)
                local last_file1 = string.sub( f:read("*a"):gsub("\n", ""), 1, 24)
                -- end
                
                -- sending image to telegram:
                domoticz.executeShellCommand('curl -s -X POST "https://api.telegram.org/bot'.. tBot  ..'/sendPhoto" -F chat_id='.. tChatId  ..' -F photo="@C:/Domoticz/screensfromcams/cam2floor/'..last_file1..'" -F disable_notification=false -F caption="Motion 2 floor"')
