HowTo: Node Red / FritzBox – Show call notification

If you have a FritzBox in your home in addition to a RaspberryPi with NodeRed, the following article could be of interest to you.

This explains how you can react to potential calls via NodeRed. As an example, a message is displayed on the dashboard as soon as a call is received on the FritzBox.

Safety instructions

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.

Requirements

Helpful articles:
To be able to use this configuration, NodeRed should of course already be installed.
How to prepare a RaspberryPi and then install NodeRed on it is described in the following articles.

The following articles describe what has to be done to prepare the RaspberryPi so far:
RaspberryPi – setup for nerdiys!
RaspberryPi – The first configuration!
RaspberryPi – Control the RaspberryPi via SSH
NodeRed – Installing NodeRed on the RaspberryPi
NodeRed – Install new nodes

Required material:

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

Log into the NodeRed configuration interface

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

Install FritzBox node

Enter FritzBox node configuration

So that the FritzBox node you have just installed can also communicate with your FritzBox, you must enter your FritzBox login data in the node configuration.

Node code for caller notification

You can respond to the call on your FritzBox with all sorts of actions. For example, you could also have a lamp turn on when a call comes in. In this example, when a call is made, a pop-up is displayed on the dashboard with the caller number and the time of the call.

To do this, copy the node code below and import it into your NodeRed installation.

Node code:

[{"id":"13066853.acf578","type":"function","z":"5ebf035f.49459c","name":"","func":"
if (msg.payload.type=="INBOUND")
{
    var output="";
    output+="Anrufer: "+msg.payload.caller+" am "+msg.payload.timestamp;
    msg.payload=output;
    return msg;
}
","outputs":1,"noerr":0,"x":510,"y":300,"wires":[["c49fb24f.fdfa9"]]},{"id":"c49fb24f.fdfa9","type":"ui_toast","z":"5ebf035f.49459c","position":"dialog","displayTime":"25","highlight":"","outputs":1,"ok":"OK","cancel":"","topic":"Aktueller Anruf","name":"Aktueller Anruf","x":700,"y":300,"wires":[[]]},{"id":"2d4a3414.8a1a4c","type":"comment","z":"5ebf035f.49459c","name":"Aktuellen Anruf anzeigen","info":"","x":270,"y":260,"wires":[]},{"id":"7665017.2302b","type":"fritzbox-callmonitor","z":"5ebf035f.49459c","device":"b6df4765.5508a8","name":"","topic":"","x":300,"y":300,"wires":[["13066853.acf578"]]},{"id":"b6df4765.5508a8","type":"fritzbox-config","z":"5ebf035f.49459c","name":"FasbFritzBox","host":"fritz.box","port":"49000","ssl":false}]

Have fun with the project

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. 🙂

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. 🙂
