I recently had that DECT radiator thermostats for the FritzBox tested and integrated into my NodeRed installation.
That's why I was naturally curious about how the FRITZ! DECT 500 RGB LED lamp works with the FritzBox and whether it can be controlled from NodeRed just as easily as the radiator thermostat.
As usual with FRITZ products, installation and commissioning was super easy. Thanks to the included and very simple step-by-step instructions, learning it took less than two minutes.
In the app, the interface of the FritzBox and (very practical) also on a connected FritzFon! You can then set all sorts of options for the FRITZ!DECT 500 Smart Home.
This means that the lamp can not only be switched on and off. The color, light temperature, saturation and brightness can also be adjusted. The lamp can be used both as powerful room lighting and as a dimmed lamp for a movie night.
With the example flow presented here in the article, you can easily configure the basic functions of the lamp via the NodeRed dashboard.
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.

So that you can install new nodes, 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 three articles describe what needs to be done to prepare the RaspberryPi:
RaspberryPi – setup for nerdiys!
RaspberryPi – The first configuration!
RaspberryPi – Control the RaspberryPi via SSH
NodeRed – Installing NodeRed on the RaspberryPi
NodeRed - import and export node code
In the following list you will find all the parts you need to implement this article.
|USB power supply / USB power supply
|SD card / SD card
|Housing / housing
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 the appropriate FritzBox node
In order for NodeRed to communicate with the connected radiator thermostats, you have to 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. You can find information about this in the following article.
NodeCode for controlling a FRITZ!DECT 500 Smart Home lamp
The following section contains the NodeCode with which you can set the basic functions of the FRITZ!DECT 500. Of course, the connection between NodeRed and your FritzBox must already be configured. How you can do this is in the article NodeRed/FritzBox – Show caller list in the dashboard described.
The current status of the NodeCode is my first draft of a control. I will definitely continue to work on it. That's why you're welcome to ask for updates if you're missing features or if this post hasn't been updated for a while.
In the current version you can adjust the color, brightness, saturation and color temperature. You will also be shown the online status - i.e. whether the lamp is connected to the FritzBox or not. Of course, the lamp can also be switched on and off via the dashboard.
Below is a view of the configuration and the actual NodeCode.
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 NodeCode in the Nerdiy Git repository under the following link:
Read out the AIN of your FRITZ!DECT 500 Smart Home lamp and enter it in NodeRed
In order for the NodeCode above to work, you now have to enter the correct AIN in your NodeRed configuration. The AIN is the identification number of your FRITZ!DECT 500 Smart Home lamp, which you need to control it specifically. How you can find 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 click on the pen symbol in the line with the entry for your FRITZ!DECT 500 Smart Home lamp
Then you can see and copy the AIN of your FRITZ!DECT 500 Smart Home lamp in the area marked red.
In order to insert the copied AIN into the NodeCode you have to do the following:
Open the “Set Lamp AIN” node and enter the AIN of your FRITZ!DECT 500 Smart Home lamp in the user data field.
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. 🙂
