Here’s another small KNX project 🫠
This time it’s quite manageable, using a 16-channel switching actuator for lighting, power outlets, and roof window drives in a museum. The new exhibition extension is to be controlled from the reception desk. For this purpose, a KNX touch panel with display is a great fit, as it allows everything to be easily operated by category.
It's on the roof and connected.
Of course, this won’t just be left like that. It will be properly mounted.
Time to show the progress, since the project has been completed since last Friday.
The 12 spots each have their own small power supply, which I had to fit into the cabinet.

A new small KNX project.
Glass canopy above the balcony with an awning, 12 spotlights, and switchable sockets. This box needs to go on the flat roof.
Later, a KNX server will be added to the distribution cabinet in the basement. This time in a proper DIN rail enclosure.
The visualization server this time is basically just a Raspberry Pi in a metal case.
The advantage is that I can easily install a different system on it if it doesn’t perform well. 
As previously mentioned, the distribution system was installed today.
In the first picture, you can see how it looked before. Only a few preparations were made, such as removing the side covers and drilling holes for wall mounting.
In the second picture, the distribution cabinet has been installed next to it. I took the photo around midday, and the wiring was essentially completed. The existing wiring was replaced with new wiring leading to the #KNX cabinet.
Since most of the programming was already done, I just had to add the labels during testing.
Tomorrow, the work continues with fine-tuning. I already set the runtime for the awnings today. Tomorrow, I’ll need to reconfigure the dimmers with an adjusted dimming curve for each lamp.
Alright, time to share something new again. This time, a bistro is getting retrofitted with #KNX. Since the electrical installation is only a year old and all the wiring runs through terminal blocks to the distribution cabinet, it’s quite straightforward to implement. A slim distribution cabinet will be added, containing the actuators, binary inputs, and the visualization server.
I already programmed the system last Thursday and configured the server as much as possible. Installation and switchover will take place on Monday and Tuesday.
Due to a power failure, the room temperature controllers have forgotten the setpoint value. As a result, they could not be set sufficiently.
I have reinstalled the program on all the temperature controllers. Next year I will look at why this happened and install new firmware.
