Hello

I want to upgrade my home with a smart home system.
Which smart home system would be best suited for this?

The following points should be covered:
- If possible, everything should be controllable via one app
- It should be possible to create rules
- All solutions should allow either replacing or continuing to use the existing switches (surface-mounted or flush-mounted)
- Everything should also be manually operable without a phone and without internet

- Control electric roller shutters: for example, I want to set the shutters to close automatically at sunset (so the time adjusts automatically each day).
We have a sliding door that lifts and slides. If it is open or ajar but not fully closed, the shutters at the door should not close and lock me out 🙂

- Control underfloor heating: all rooms have underfloor heating with individual thermostats. I want to set the temperature once, for example living room 21°C (70°F) and bedroom 18°C (64°F), and the system should then regulate everything else to maintain the temperature.

Later, I want to add the following:

Light switches: I want to control all light switches via the app (on/off), but they should also remain manually operable.

Window sensors: to check if any window is still open or to notify me if it is raining and a window is open.

I will also install a Hörmann sectional garage door later, which I would like to integrate (but it wouldn’t be a big issue if it needs to run separately).

Googling "BEG" or "Federal Funding for Efficient Buildings" is very helpful. There were quite a few changes in January. In general, it’s about funding everything related to energy saving and the integration of the trades involved. This has nothing to do with the KfW loan. However, if your developer clearly has no knowledge about the topic itself, I find it quite questionable if they are supposed to provide you with eligible offers. For that, one would need to 1. understand what is possible in the field of building automation and 2. know which parts and combinations are eligible for funding. I’m pretty pessimistic in your case.

There are already other threads about funding here, where you can get an idea of what is covered.

Which forums are those? With so many terms, protocols, and providers, I feel completely lost...

They are usually very manufacturer-specific. Unfortunately, referring to other forums is generally not allowed here or, if it happens, it is usually very cryptic.
What are your requirements?

I'm still gathering those... :-) But I would like to get an overview and understand everything in this whole jungle.

It depends on what exactly you want. All the retrofit options available tend to be standalone solutions. In other words, they usually cover one or two aspects well, but never everything, which often results in a patchwork mix of several products that "somehow" work together.
