How To: Node Red / FritzBox – View Caller List in Dashboard

In addition to the caller ID, you can also view the caller log of the Fritzbox in NodeRed.

How to do this is explained in the following article.

Hints for our lovely english readers: Basically, many of the articles on Nerdiy.de are translations from the original german articles. Therefore, it may happen here and there that some illustrations are not available in english and that some translations are weird/strange/full of mistakes or generally totaly wrong. So if you find some obvious (or also not obvious) mistakes don't hesitate to leave us a hint about that in the comment section. 
Also please don't get confused, that instead of a "dot" often a "comma" is used as decimal separator. 🙂

Safety instructions

I know the following hints are always a bit annoying and seem unnecessary. But unfortunately, many people who knew it "better" from carelessness lost their eyes, fingers or other things or hurt themselves. In comparison, a loss of data is almost not worth mentioning, but even these can be really annoying. Therefore, please take five minutes to read the safety instructions. Even the coolest project is worth no injury or other annoyance. https://www.nerdiy.de/en/sicherheitshinweise/

Requirements

Helpful Articles:
Of course NodeRed should already be installed so that you can take over this configuration.
How to prepare a RaspberryPi and then install NodeRed on it is described in the following articles.

The following articles describe what to do to prepare the RaspberryPi:

• RaspberryPi – Setting up for Nerdiys!
• RaspberryPi – The first configuration
• RaspberryPi – Controlling the RaspberryPi via SSH
• NodeRed – Installing NodeRed on the RaspberryPi
• NodeRed – Install New Nodes
• NodeRed – Import and Export Node Code
• NodeRed – Creating a User Interface with Dashboard Nodes

Required material:

In the following list you will find all the parts you need to go thorugh this article.

---

Log in to the NodeRed configuration interface

Before you can edit your NodeRed configuration you must - if activated - first log in to the NodeRed configuration interface.

---

Install FritzBox-Node

So that NodeRed can communicate with your FritzBox you have to install the node “node-red-contrib-fritz”. How to install Nodes is described in the article NodeRed – Install New Nodes.

---

Enter FritzBox node configuration

So that the just installed FritzBox node can communicate with your FritzBox, you have to specify your FritzBox login data in the configuration of the node.

Node code to display the caller list in the dashboard

For this example, you need the dashboard node in addition to the FritzBox node. The dashboard will then display a table of recent calls. After inserting the node code listed below, do not forget to position the dashboard element correctly on the dashboard.

For more information on handling dashboard nodes, see NodeRed – Creating a User Interface with Dashboard Nodes

The code below is the code from the function node of the listed node configuration. In it you can change the table output and, for example, also change how many of the last entries are shown.
Change the “10” in the line “for (var i = 0; i <10; i ++)” to the desired value.

var IO=[];
var Datum=[];
var Nummer=[];

    for (var i = 0; i<10; i++) { if(msg.payload.Call[i].Type==1) { //Eingehender Angenommener Anruf IO[i]=">";
            Datum[i]=msg.payload.Call[i].Date;
            Nummer[i]=msg.payload.Call[i].Caller;
        } else if(msg.payload.Call[i].Type==2)
        {
            //Eingehender Nicht-Angenommener Anruf
            IO[i]=">>";
            Datum[i]=msg.payload.Call[i].Date;
            Nummer[i]=msg.payload.Call[i].Caller;
        } else if(msg.payload.Call[i].Type==3)
        {
            //Ausgehender Nicht-Angenommener Anruf
            IO[i]="<<";
            Datum[i]=msg.payload.Call[i].Date;
            Nummer[i]=msg.payload.Call[i].Called;
        }
    }
msg.payload.IO=IO;
msg.payload.Datum=Datum;
msg.payload.Nummer=Nummer;
return msg;

Unfortunately, I could not insert the NodeCode directly here because the HTML code contained in it somewhat “confuses” the look of the website.

You can find the NodeCode here in the Nerdiy-Git:

• https://github.com/Nerdiyde/NodeRedSnippets/blob/master/FritzBoxCalllist.txt

Alternative version

Here is a slightly improved version of the flow shown above.

This allows the accepted, missed and made calls to be displayed in separate tables.

Have fun with the project

I hope everything worked as described. If not or you have any other questions or suggestions, please let me know in the comments. Also, ideas for new projects are always welcome. 🙂

P.S. 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 appreciate it that I share these information with you, I would be happy about a small donation to the coffee box. 🙂
