HowTo: Node Red - Read out the temperature of the FRITZ! DECT Repeater 100

The FRITZ! I recently bought a DECT repeater to improve the range of my DECT phones.

Unfortunately, my Fritz Box has to be in the basement because that's the only place where a suitable connection to the Internet is possible. Actually no problem. However, the quality and range of the DECT connection between the telephone handset and FritzBox suffers as a result.

So I have the FRITZ! DECT Repeater 100 installed and connected to my FritzBox. The range of my DECT phones is now much better. At the same time, the repeater also extends the range of my Fritz Smart Home devices.

But now I was curious whether I could integrate the repeater into my smart home in some way. Unfortunately, you cannot switch the existing socket, as the socket in the housing is only intended to prevent the socket from being permanently blocked.

What can be used or read, however, is the temperature of the FRITZ! DECT Repeater 100. This has an internal temperature sensor, the temperature of which can also be displayed via the FritzBox interface. Practically, you can also use this temperature value Node Red read out.

How you can proceed to read the temperature using Node Red is described in the following article.


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.

Read out the AIN of your FRITZ!DECT 100 and enter it in NodeRed

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 100 repeater, which you need to be able to specifically control or read it. 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.


Log into the NodeRed configuration interface

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

View of the login dialog. Here you have to enter the login data that you specified during the configuration of the login. You can find information about this in the article NodeRed - set up user login.

Install the appropriate FritzBox node

In order for Node Red to communicate with the connected repeaters, you must set the node “node-red-contrib-fritzapi" install. How to install your node is described 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 measured temperature on the dashboard. You can find information about this in the following article.


Node Red code for retrieving the temperature of a FRITZ!DECT 100 repeater

You can use the Node Red code linked below to check the temperature of your Fritz DECT repeater. The temperature is displayed on the Node Red Dashboard, but can of course also be further processed internally.

View of the flow in the Node Red configuration view.

View of the controls in the Node Red dashboard view.

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

For this purpose, the login information for your FritzBox should be entered in the red marked area.

You can find more information about this in the article

In order to be able to use the Node Red code, you still have to enter the AIN of your Fritz DECT Repeater.

The AIN is the identification number via which the repeater is addressed. How you can find out this AIN is in the article Fritz Box – Find out the AIN of your SmartHome device described.

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:


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. 🙂
