HowTo: NodeRed - Control and read out FRITZ DECT 200 socket using NodeRed

The FRITZ!Box is not only a very good router for the home network. Equipped with the right Smart Home accessories, it can also become the Smart Home center of your house or apartment. Everything you need is already installed in the FRITZ!Box. New sensors or actuators are simply wirelessly connected to the FRITZ!Box via the DECT standard.

One possible actor is the FRITZ!DECT 200 socket. After you have connected it to the Fritz Box, you can control it via the Fritz Smart Home App or according to defined rules or times.

If you want a little more and more individual control, you can also control the socket using Node Red.

This article describes what you have to do to integrate a FRITZ!DECT 200 smart home socket into your Node Red environment.

Safety instructions

I know the following tips are always somehow annoying and seem unnecessary. But unfortunately, many people who knew "better" have already lost eyes, fingers or other things or injured themselves due to carelessness. In comparison, a data loss is almost not worth mentioning, 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 an injury or other trouble.

Read out the AIN of your FRITZ!DECT 200 socket and enter it in Node Red

In order for the Node Red code below to work, you must enter the correct AIN in your Node Red configuration. The AIN is the identification number of your FRITZ DECT Smart Home device, which you need to be able to control or read it specifically. How you can find out the AIN using the FritzBox configuration interface is in the article Fritz Box – Find out the AIN of your SmartHome device described.

Install the appropriate FritzBox node

In order for Node Red to be able to communicate with the connected socket, you must use the Node "node-red-contrib-fritzapi" to install. How your node is installed in the article NodeRed - Install new nodes described.

You should also have already installed and configured the dashboard node. This is used to display the retrieved data on the dashboard. You can find information about this in the following article.

• NodeRed - Create a user interface with dashboard nodes

Node Red code for controlling the FRITZ DECT 200 Smart Home socket

With the Node Red code linked below you can control your Fritz DECT 200 socket and retrieve its data. The temperature, measured power and the switching status are displayed on the Node Red Dashboard, but can of course also be processed internally.

In order for the Node Red code to work, the connection between Node Red and your FritzBox should already be configured.

You can find more information about this in the article

• NodeRed/FritzBox – Show caller list in the dashboard .

How you can import the NodeCode linked below into your NodeRed environment is in the article NodeRed - Import and export node code described.

As always, you can find the Node Red code in the Nerdiy Git repository under the following link:

• https://github.com/Nerdiyde/NodeRedSnippets/blob/master/snippets/fritz_box_control_dect_200_socket.json

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 also always welcome 🙂 .

P.S. Many of these projects - especially the hardware projects - cost a lot of time and money. Of course I do it because I enjoy it, but if you think it's cool that I share the info about it with you, I'd appreciate a small donation to the coffee fund 🙂 .
