ᐅ Smart Home for Older Homes, Wireless-Based, Seeking Broad Compatibility

Hello everyone,

I have a question about smart homes.
I will soon be partially renovating / fully refurbishing my childhood home
- 10x10m (33x33 feet)
- 2.5 stories
- Fully renovated / refurbished in 1980

Partial/full renovation means some structural changes,
a new staircase, removing some walls and installing beams, new floors,
new ceilings, and new walls.

I want a smart home system that primarily controls topics such as
- Intelligent lighting control (motion sensors, people counters, etc.) and shading
- Efficient heating
- Control of air conditioning and decentralized ventilation units
- Garage door
- Integration of photovoltaic system with energy storage
- Charging stations
- And a few other small features

I would prefer a wireless solution because it’s not yet clear if the electrical wiring will be updated everywhere. Also, I want to be able to easily add future expansions.
My main requirement for my smart home is that once it is set up, it is smart because I don’t have to constantly turn lights on manually via an app; everything should be as automated as possible (in my opinion, using an app is not smart—smart means not having to actively manage daily tasks). 🙂
Also, having a broad, open platform is important to me; fully closed systems with severely limited actuators/sensors are basically out of the question.

I’m fine with openHAB or similar platforms—I think you can’t avoid them if you want flexibility (different technologies), right?
Now I came across “homee” combined with EnOcean, which sounds promising in principle.

Where I’m stuck and what my question is:

Would you go directly with a Raspberry Pi running openHAB or similar software and connecting different technologies, or would you use something else as the central controller?

Thanks for your brainstorming feedback, best regards
