Hello dear forum community,
We are currently at the very beginning of planning the electrical system and are quite undecided about whether a smart home system (KNX, etc.) makes sense or not.
Our requirements are as follows:
- Control of blinds including a timer function
- Lighting control
- Video and intercom system, which should be installed in the basement, living/dining room, and hallway on the upper floor
- It does not necessarily need to be app-controlled, and if it is, it only needs to work when we are at home (the door does not need to be opened remotely via app)
- Motion sensors on stairs and hallways
- Dimmable lighting
Each room will also have a room thermostat. This does not necessarily need to be centrally controlled.
I have recently come across the GIRA System 3000. Does anyone have experience with it? From what I have read, it should cover all of the stated requirements. Have we forgotten anything essential that should definitely be considered?
Thank you very much for your experiences and assessments.
Best regards and have a nice evening

A sensible approach is to combine the season, presence of occupants, sun position, and indoor temperature. This way, you can either provide shading or use the sunlight to warm up the space. However, this is rather difficult to achieve using the internal logic functions of the actuators. Shading also offers many other attractive possibilities. This should be manageable with internal logic. For example, presence can be linked via presence monitoring with a shading lock or similar. Sun exposure and indoor temperature are standard with a weather station plus a roller shutter actuator. I’m not sure what the season would be useful for in this context.

It should work with the actuator. It has the option to control shading based on both outdoor and indoor temperatures to maximize solar gains.
I haven’t set this up myself yet.
I want to base it on outdoor temperature. I consider using indoor temperature less useful in a new building with a slow system like underfloor heating. Thanks for the info, I’ve now looked more closely at the actuator. There are quite a few parameters, for example: shading active when azimuth angle is within a certain range, shading active when solar elevation angle is within a range. The question is whether factory presets are useful here, or if you just have to experiment until it fits reasonably well. Alternatively, one could also develop a more complex logic from scratch. Does anyone here have experience with this?

No logic engine or similar is required for this. Both are standard features of the MDT application.
We also had both briefly activated, but for us it doesn’t really make sense. Outside temperature doesn’t tell you anything about solar radiation. Even at -5°C (23°F), the sun can still overheat your house… Are you using the default settings, or did you have to experiment a lot until it worked?
