@Vauxdvihl openweathermap discontinued their 2.5 api. so the url in the module might be wrong. Check the configuration possibilities for your module and see if you can choose the 3.0 api.

@karsten13 that is exactly what I did. I like having it outside the config.js so the config.js doesn’t grow to be a huge file. And so if I mess up when I add to the compliments.json, I won’t break the entire mirror.

I’m adding a whole lot of birthdays and lots of family specific dates. I like having the remoteFile setting so I can keep this data out of config.js.

Thank you for all you have done! I am a newbie to MagicMirror (two months since I started playing with it and figuring it out) and I have installed several of your modules. I’m learning so much about node.js and javascript by tweaking their configurations and I’m impressed. I just found this note from you saying you were going to move on to new things as life has been changing so much for you.
I found MM and your modules because I was creating change in my life. Good LUCK and may you find interesting challenges and satisfaction whatever you end up doing.

And… Thank you!

p.s. I hope you do lurk from time to time and check in on us. You will be missed for sure.

@Manu85 I do not understand what you wrote. I think you want to change the size of the content you are grabbing from a different website.

MMM-SmartWebDisplay creates an iframe and shows a webpage inside that iframe.

Because you are displaying the contents of your link inside an iframe, you are stuck with whatever is coded in that frame. You can’t change what is in it. The web page you chose contents are set to a fixed size by the html code that creates that page.

The width and height in the config.js only affect the size of the iframe that you created with the module. Those values can not affect what is inside the iframe that are hosted on a different server.

Perhaps you can find a different source for your content? If you found something that isn’t set to a fixed size then it may display relative to the size of the iframe you build locally with the module.

This is by design of the www. It prevents hijacking content. If you want to read about it, it’s called same-domain policy.

@aunrea
What is happening is that npm can’t find config:check in /home/pi/

You have to move into the Magicmirror folder before running
npm run config:check

Sam,

Thank you for this MMM-PythonPrint. More than the sample module this really helped me follow how to wrap my head around how the script.js node_helper and anything else work together. The way you worded the variables and the input and output text really made sense and made it easy to follow what is happening. I am learning a lot. Again, Thank you.

Kelly

@sdetweil your explanations helped a lot. I debugged using a timer in the node_helper to fake detecting different types of button press and my module will send magic mirror notifications. (So, if I can detect the actual physical events I’m pretty sure my script will work.

I think it’s the node package I’m trying to use that is the problem.

I even got so far as to figure out that a dependency of the package I want to used wasn’t compiled for Node version 16. which i what I’ve got running on my Mirror pi. I figured out it is c++ and even figured out how to recompile it with node-gyp and make. so now I do not get any errors in the pm2 error log. but now instead of a black screen electron, I don’t get electron opening a window at all. I check the PM2 logs. There are no errors in the mm-error log. It is blank.
However, the pm2 mm-out log is being added to over and over, so electron and MagicMirror are running. and the error keeps being repeated in the mm-out log.

The error which i’ve googled and gotten no working result for is:

ERROR Error: Cannot find module 'bindings'. 

Yet there is a bindings folder in the node_helper folder.
Is there a way to find out what path is being used to try to find “bindings”.

Or maybe the package I’m trying to use just is too much of a mess to keep screwing with. It sure seems like it would be super useful. I wanted to add a few physcial intermittant buttons and be able to assign multiple uses to them. Funny thing is… it works great when I run the test script in the command line using node.

By the way, this learning nodejs and module development is not all that easy.

@Manu85 Youtube allows you to form the url requesting the video in a way that tells YouTube what size you want the YouTube player to be. The YouTube developers do that purposely as they make money from ads they show you.

Unfortunately the isstracker.spaceflight.esa.int website doesn’t allow you to do that.

Every website developer makes choices for their own website. We may not like what they choose.

@JohnGalt
I see you got your module choice working.
jclarke0000 is the one I’m using.

This is my first working module. I wanted to make one button do more than one thing. This module uses a python script to poll the button state. The button can be pressed and released or it can be held down for a long period of approx 4 seconds.

I am currently using MMM-OneButton with the MMM-Pages module to PAGE_INCREMENT the pages upon a button press.
And to ARTICLE_NEXT for the default news module when the button is held.

I have to give Sam kudo for all his examples he has posted on this forum. He’s really helped me a lot.

I plan on making it even more useful by adding in the obligatory screen on/off. reboot pi, etc. But I am excited that I’m finally figuring this stuff out enough to actually make a working module.

@KristjanESPERANTO abd @sdetweil

for MagicMirror purposes, is there a preferred style to be used for modules?

@sdetweil AHHHH!!! AHA moment here. That graphic really helps me understand.

Not everyone runs a single mirror on it’s own computer like I do. Some use the MM like digital signage. One beefy server doing the heavy lifting and then a bunch of lightweight microcomputers just displaying the MM front end.

The Kid node_helper is running on the server! While the MotherModules are only in their own browsers on whatever weenie machine is displaying the front end of MM. (might not be weenie but might be.)

so I see how I would have to be really careful about unique id’s in an environment where I run the MagicMirror on a server and have a bunch of displays all connected to it. May not want the KidModule blasting the same info out to every single display. Unique ID’s mean info would only go to the display it’s intended for.

Though I supposed it’s possible that one would want the same info to go out to every display.

I was thinking of setting up a few displays showing golf tournament scores and in that situation, I’d want every single mirror to show the same info. So in this use case, I wouldn’t want the unique id at all.

I think we have five ways to use when sending notifications around in MM. I’d like to know if I finally have a grasp on how it works. Can someone confirm if I’ve got this right?

In my mental analogy I kind of imagine a node_helper is like a child of the mother module which spawned it.

So when I need to send information around inside MagicMirror this is how I think it works:

1. my MotherModule can send info to it's own kid node_helper with sendSocketNotification
2. my MotherModule can send info to the MM in this [edited: browser instance] with sendNotification
3. my node_helper kid can send to it's MotherModule with this.sendSocketNotification
4. my node_helper kid to all it's cloned MotherModule instances, but no module outside the immediate family with sendSocketNotification
	(ie maybe I have four instances of the same module just using diff header names and setup with four diff config variables to kickstart them. I better be careful and keep track of which Mom send what info that the kid is replying to, or all the Mom's in the family will know the kid's secrets.)

5. can my kid node_helper sned info to the whole system? not directly possible.  The  kid node_helper has to send info to the MotherModule and then MotherModule will be able send it to the [edited: browser instance] .

“this.” makes it a private conversation between the specific instance of the Mother Module and the node_helper . Not having “this.” make it more public. In the case of the node_helper, it send to every instance of the Mother Module if there is more than one in use; and, in the case of the MotherModule, it blasts the info out into the entire MagicMirror.

I’m looking at a lot of modules while trying to roll my own and see a lot of differences in syntax style, I wonder if one way of creating a function is better or more efficient than the other.

init: function () and init()

I see both ways done in node_helper.js in different modules.

module.exports = NodeHelper.create({
    init: function () {
      console.log ("init module helper ");  
    }
})

and

module.exports = NodeHelper.create({
    init () {
      console.log ("init module helper ");  
      }
});

@Vauxdvihl openweathermap discontinued their 2.5 api. so the url in the module might be wrong. Check the configuration possibilities for your module and see if you can choose the 3.0 api.

@TDMPro2K great workaround!

@Lipax try dialing down the sensitivity, it’s probably picking up dust or something small you can’t see.

@sdetweil
what was happening is that no matter if i used the full path or just the folder name like this
-b /home/pi/MMbackup2
-b MMbackup2
the script always used it’s own folder name of MM_backup.

when i tried to run from your repository,
Illegal option '- ’

I tried a local copy pulled a fresh copy from your GitHub and tried again
using -s MagicMirror
and -b MMbackup3

bash -c ./mm_backup.sh -p -b MMbackup3 -r MMbackup2 -u Kayakbabe -e user@email.com -m "second backup after build finished "

the backup folder was still created MM_backup and not MMbackup3.

Then I tried removing the -p option and I get this
bash -c “$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror-backup-restore/main/mm_backup.sh)” -b MMbackup2 -r MMbackup2 -u Kayakbabe -e email@mydomain.com -m “first backup after build finished (or whatever)”
environment: line 155: [: too many arguments
checking for backup folder MMbackup2
folder doesn’t exist, creating backup folder /home/kelly/MMbackup2
backup folder is /home/kelly/MMbackup2
username specified with -u temp doesn’t match the user in the github repo MMbackup2, aborting

Note i used my correct email, just don’t want it out here to get scraped. And the name and email DO match my github.
I run git remote-v in the folder it created (MM_backup) and there is no git .

I have to tell you that I am awed! And really considering making a round MM now. It is fabulous!

@sdetweil

I’ll put this in my own words to see if I’m understanding what I am to do.

Depending on how I create my repository on github will determine my next step.

1. Create respository on GitHub (private is most preferable since I might have private info in my magic mirror config file and I don’t want that public via GitHub).

Note: This process is easier if you create an empty GitHub Repository.

2. If I created an empty GitHub Repsitory:
   2.a.Run the backupscript using the flags on the backup script for repository name, source folder, backup destination folder, github userid, etc.
   2.b. from the backup desitnation folder run the command
   git push

3. if I created GitHub repository with a readme:
   then I’ve made a big mess and shouldn’t have done that. So delete the local folder and github repository and start over.

Results
I ran this

bash -c ./mm_backup.sh -s /home/pi/MagicMirror -b /home/pi/MMbackup2 -r https://github.com/Kayakbabe/MMbackup2.git -u Kayakbabe -e email@mydomain.com -m 5thTry 

And got this:
folder created with name /home/MM_backup
files created inside /home/MM_backup
no folder named MMbackup2

I also tried with -b /home/pi/MMbackup2
and still get home/pi/MM_backup created

i don’t have a folder named MMbackup2 on my pi at all.

I then manually created /home/pi/MMbackup2
ran my command again and still no files were placed in MMbackup2. i tried both =b /home/pi/MMbackup2 and -b MMbackup2 to no avail.

I noticed .git was created in the MM_backup folder along with the files the script created.

I ran git remote -v and get no output. (Just to make sure, i went to a diff local git folder and ran git remote -v and it shows the origins for fetch and pull.) so I think the .git being created in the MM_backup folder isn’t correct.

My questions are:

What is wrong with my flags that my backup folder isn’t being create with the folder name I chose?

Was the backup script supposed to do all the git stuff for me, like the git remote add origin and add files and set the branch and message?
So that, all I am supposed to have to run git push?

Or, am i supposed to now do all the following stuff?

git remote add origin https://github.com/<USER>/<repo>.git
git branch -M main
git push -u origin main
