HowTo: Fritz Box - Find out the AIN of your SmartHome device

SmartHome devices that are compatible with the FRITZ!Box are addressed via an AIN. This AIN is a unique identification number that is assigned to the respective device.

For example, if you use Node Red to measure the temperature of a Fritz DECT radiator thermostat set or one FRITZ!DECT 500 smart home lamp If you want to switch on and off you have to find out the respective AIN.

How you can do this 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!Box Smart Home device

As mentioned above, the AIN is the identification number of the smart home device that you need to control it or read data from it. How you can find this out using the FritzBox configuration interface is described in the following pictures.

To do this, first switch to the configuration view of your FritzBox. Then click on:

  • “Device Management”
  • And then on the pen symbol in the line with the entry of your desired DECT device. (In this example one FRITZ!DECT 500 smart home lamp)

Then you can see and copy the AIN of your SmartHome device in the area marked in red.

You can then paste the copied AIN in the appropriate field of the Node Red code.

Under the following link I have summarized a few of the articles for which you may need the AIN of a FRITZ SmartHome device.

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. 🙂
