#!/bin/bash

# Set default values for environment variables
: "${HTTP_URL:=https://webcam.connect.prusa3d.com/c/snapshot}"
: "${DELAY_SECONDS:=10}"
: "${LONG_DELAY_SECONDS:=60}"

FINGERPRINT="xxx"
TOKEN="xxx"
SNAPSHOTURL="http://127.0.0.1:8080/?action=snapshot"

while true; do
    # grab from octopi
    curl -s "$SNAPSHOTURL" --output /tmp/output.jpg

    # If no error, upload it.
    if [ $? -eq 0 ]; then
        # POST the image to the HTTP URL using curl
        curl -X PUT "$HTTP_URL" \
            -H "accept: */*" \
            -H "content-type: image/jpg" \
            -H "fingerprint: $FINGERPRINT" \
            -H "token: $TOKEN" \
            --data-binary "@/tmp/output.jpg" \
            --compressed

        # Reset delay to the normal value
        DELAY=$DELAY_SECONDS
    else
        echo "Octopi snapshot returned an error. Retrying after ${LONG_DELAY_SECONDS}s..."

        # Set delay to the longer value
        DELAY=$LONG_DELAY_SECONDS
    fi

    sleep "$DELAY"
done

And make it executable:

1

chmod +x /usr/local/bin/prusaconnect_upload_cam.sh

You can test it by running the script manually:

1

/usr/local/bin/prusaconnect_upload_cam.sh

You should see the camera image being uploaded to Prusa Connect.

Once done, you can move forward and run it in the background, create /etc/systemd/system/prusaconnect_upload_cam.service:

[Service]
ExecStart=/usr/local/bin/prusaconnect_upload_cam.sh

[Install]
WantedBy=multi-user.target

and then start and enable it:

1

systemctl enable --now prusaconnect_upload_cam.service

That’s it! You should now see your OctoPrint camera feed in Prusa Connect.
