For a long time I was looking for a way to display the data I collect with NodeRed from my SmartHome comfortably on the MagicMirror.
\nThanks to the many plugins for the MagicMirror and NodeRed, this was implemented faster than expected. How it works is described in the following article.<\/p>\n

Safety instructions <\/span><\/h2>\r\n

I know the following notes are always kind of annoying and seem unnecessary. Unfortunately, many people who knew "better" have lost eyes, fingers or other things due to carelessness or injured themselves. Data loss is almost negligible in comparison, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Because even the coolest project is not worth injury or other trouble.<\/span>

Requirements<\/h2>\n

Helpful articles:
\n<\/strong>Before you start with the installation you should prepare the RaspberryPi so that it is accessible via the network and controllable via SSH.<\/p>\n

Log into the NodeRed configuration interface<\/h2>\r\n

Before you can edit your NodeRed configuration, you must - if activated - first log into the NodeRed configuration interface.<\/p>\r\n

Creating the data source in NodeRed as JSON<\/h2>\n

In this example, the MagicMirror displays data from the RaspberryPI running NodeRed.
\nNodeRed provides this data as JSON, which the MagicMirror fetches at regular intervals and displays on its screen. You don't need to install any new nodes, because the data source is assembled from the standard nodes.<\/p>\n

To do this, you need to build the following flow.<\/p>\n

It is easier to insert the following node code:<\/p>\n

Now you will be shown the address (but pay attention if you have to prefix it with \"https:\/\/\" or \"http:\/\/\").<\/p>\n
https:\/\/IP_EURER_NODE_RED_INSTALLATION:1880\/daten.json<\/pre>\n
will display a JSON with the data you entered. This can now in turn be displayed by a MagicMirror plugin on it.<\/p>\n
\"\"<\/a>
JSON data as displayed to you in the Firefox browser. This is good for debugging because it also shows errors in the JSON structure.<\/figcaption><\/figure>\n
\n
Installing the module<\/h2>\n
To display the data provided by NodeRed as JSON on the MagicMirror you have to install the module \"MMM-JsonTable\". You can find it under\u00a0https:\/\/github.com\/timdows\/MMM-JsonTable<\/strong><\/em><\/a>.<\/p>\n
Install this on your RaspberryPi. How to install modules is described in the following article:
\nMagicMirror - Install 3rd party modules<\/strong><\/em><\/a><\/p>\n
\n
Configuration of the module<\/h2>\n
The configuration of the module is kept simple, as the structure of the displayed data is given by the JSON.<\/p>\n
sudo nano ~\/MagicMirror\/config\/config.js<\/pre>\n
\"\"<\/a>
So open the configuration file of your MagicMirror and insert the module configuration.<\/figcaption><\/figure>\n
{\r\n   module: 'MMM-JsonTable',\r\n   position: 'top_right',\r\n   header: 'raspi-status',\r\n   config: {\r\n      url: 'https:\/\/IP_EURER_NODE_RED_INSTALLATION:1880\/daten.json', \/\/ Required\r\n      arrayName: 'data', \/\/ Optional\r\n      tryFormatDate: false\r\n   }\r\n}<\/pre>\n
\"\"<\/a>
Of course you have to replace \"IP_EURER_NODE_RED_INSTALLATION\" by the IP address of the RaspberryPi# on which your MagicMirror is running.<\/figcaption><\/figure>\n
\n
Modification of the module for self-signed SSL certificates<\/h2>\n
Unfortunately, there is a problem with the MagicMirror plugin (current: November 2018). This does not allow HTTPS connections if the SSL certificate in question is self-signed.
\nThat is, if you have installed your NodeRed installation as described in the post NodeRed - Encrypt connection<\/a><\/strong> secured with a self-signed SSL certificate, the MagicMirror plugin will not be able to load or display the data from the JSON.<\/p>\n
To solve this problem there is a small workaround that disables this security feature. This means the MagicMirror plugin can accept self-signed SSL certificates and displays the data of your JSON.<\/p>\n
To do this, change to the module folder of the MagicMirror module you just installed.<\/p>\n
cd MagicMirror\/modules\/MMM-JsonTable\/<\/pre>\n
\"\"<\/a><\/p>\n
There you open the file \"node_helper.js\" with the following command:<\/p>\n
sudo nano node_helper.js<\/pre>\n
\"\"<\/a><\/p>\n
In the opened file you should now find the line with the following content:<\/p>\n
request({ url: url, method: 'GET'}, function (error, response, body) {<\/pre>\n
\"\"<\/a>
In the still uncorrected file you have to find the line with \"request({ url: url, method: 'GET'}, function (error, response, body) {\".<\/figcaption><\/figure>\n
In this line you have to insert the command \", rejectUnauthorized: false\" after the \"...method: 'GET'\".
\nThe line should then look like this:<\/p>\n
\u00a0request({ url: url, method: 'GET', rejectUnauthorized: false}, function (error, response, body){<\/pre>\n
\"\"<\/a>
The corrected line then looks like this.<\/figcaption><\/figure>\n
\"\"<\/a>
Afterwards you save the file again by pressing \"CTRL+X\", then confirm with \"J\"...<\/figcaption><\/figure>\n
\"\"<\/a>
...and leave the file with \"Enter\".<\/figcaption><\/figure>\n
Last but not least you have to restart your MagicMirror installation by entering the following command:<\/p>\n
pm2 restart mm<\/pre>\n
After restarting and reloading the MagicMirror view, you will see the data from the JSON \ud83d\ude42 .<\/p>\n

Have fun with the project<\/h2>\r\n
I hope everything worked as described for you. If not or you have questions or suggestions please let me know in the comments. I will then add this to the article if necessary.
Ideas for new projects are always welcome. \ud83d\ude42<\/p>\r\n
PS Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do this because I enjoy it, but if you think it's cool that I share the information with you, I would be happy about a small donation to the coffee fund. \ud83d\ude42<\/strong><\/p>\r\n
