Hello Mastermind1, thank you very much for your feedback.
Unfortunately no, although the boxes are 7.5 cm deep, there are so many cables in almost all the boxes that there is no space for the actuator, and I cannot or do not want to deepen the boxes, as I would certainly have to move quite a few cables aside.
The effort with the roller shutter box is unfortunately also very high.
As of today, I will approach it this way, meaning that Lupus is a pure alarm system and I use Homematic flush-mounted actuators as "smart home". I will test this next weekend, i.e. the actual control will be replaced by the actuator :-)
I myself have retrofitted flush-mounted actuators for roller shutters/blinds in tight boxes. Even in shallow hollow wall boxes, it is doable with a bit of order. In deep boxes like yours, it is more than doable. Additionally, good new Wago connectors (which have become significantly flatter) – and then the wiring works well.
For me, it became the wireless protocol Z-Wave with various Fibaro actuators. These are the flattest Z-Wave actuators on the market. Z-Wave uses mesh technology to improve range within the house. That means the actuators themselves act as repeaters for radio signals to other actuators when needed.
I program with IP-Symcon. Software that supports everything currently available on the market (wireless systems, wired bus systems, and much more).
Homematic also has its justification for existence. Unfortunately only one manufacturer. I would have concerns about that. Although the manufacturer (eq3) has been around for a long time. In the meantime, eq3, in my opinion, produces for too many fields (Miele/Bosch?/Telekom/RWE/.....). But Homematic itself enjoys great popularity.
Z-Wave, on the other hand, comes from numerous manufacturers. The selection is constantly growing. Off the top of my head, I can name:
Fibaro
Qubino
Popp
Dlink
Heatit
Philio
Logihome
and more.
The selection is now much larger than Homematic. Whereas Homematic is quite sufficient for the basic things.
But also, if you look for a high-quality multi-button switch with good tactile feedback, illumination, and no battery operation, you won’t find anything decent with Homematic.
Google zhc5002 (conversion kit for a Gira 6-button multi-switch).
That way, you get 6 switching options in a 55 standard frame ;-)
Z-Wave can be programmed with different solutions. Ready-made boxes with simple setup assistants. Or software solutions for the tinkering fun.
As I said, I use IP-Symcon because I was able to combine different systems with it (Z-Wave, Zigbee, 1-wire, Modbus from my photovoltaic system, weather station from Oregon Scientific, and much more).
I am critical of manufacturer-specific solutions that are not based on any standard.
