I added a script to this topic that should see you covered:

https://forum.magicmirror.builders/topic/361/how-to-update/12?page=2

@dam4 It is likely that two things are wrong.

First the script needs to be executable so please run:

$ chmod u+x update.sh

this will add execute permissions for the file owner to the file. Have a look at man chmod for more detail.

The next thing is to make sure that Linux knows where to look for it. This can be quite a complicated subject involving descriptions of the $PATH environment variable and all sorts. But the easy way to do it is to add a relative or absolute path to the start of the command. So from the command prompt in the folder where the script exists try:

$ ./update.sh

where the . means “this folder”. For the cron tab through you might want to use the full path something like:

0 2 * * * /full/path/to/file/update.sh

Hope at least some of that is meaningful for you.

@mortenbirkelund just a note if you put a console.log() in the node_helper, then it apears on the command line output (or PM2 out.log if you are using PM2)

@mortenbirkelund these console.log() statements are not crated in the node application, but in the browser. Open the mirror in a main stream browser (IE or chrome or something) and hit F12 which will bring up the dev tools look in the console there for your message.

I use this script, which comes with no guarantee:

 #!/usr/bin/env bash

cd /home/pi/MagicMirror
echo "######### CHECKING MAGIC MIRROR ##########"
git fetch
if [ $(git rev-parse HEAD) != $(git rev-parse @{u}) ]
then
    echo "######### UPGRADING MAGIC MIRROR #########"
    git pull
    npm install
else
    echo "######## NO UPGRADE REQUIRED #########"
fi
echo ""

cd modules

for directory in *; do
    if [[ -d ${directory} && ${directory} != "node_modules" && ${directory} != "default" ]]; then
        echo "######### CHECKING ${directory} ##########"
        cd ${directory}
        git fetch
        if [ $(git rev-parse HEAD) != $(git rev-parse @{u}) ]; then
            echo "######### UPGRADING ${directory} #########"
            git pull
            if [[ -e "package.json" && -f "package.json" ]]; then
                npm install
            fi
        else
            echo "######## NO UPGRADE REQUIRED #########"
        fi
        echo ""
        cd ..
    fi
done

The simple answer is no not really.

I have done some experimentation and if I run the mirror in chrome from the server machine and then cast that page then a still snapshot of the mirror appears on my cast device.

@Mykle1 lve your enthusiasm

Have emailed you with some instructions, but check:

@izanbard Of course if you already have a webpage with exactly the right stuff on it, then you could use the iframe module.

@Richard238

serving it up via Apache/MySQL/PHP.

I can help modify the scrip that servers up the data for viewing and instead of returning HTML it could easily return JSON. That would be step one. To help I would need to see your php files and know what url you are using to access the PHP page. either PM them to me, or point me at a repo.

Step two would be writing a MM module that gets the JSON and displays it right. I may be able help here too.
