ᐅ Which home automation or smart home system is recommended?

Hello everyone,

We recently purchased a single-family house and are currently renovating it extensively. As part of this, the entire home electrical system needs to be replaced, which we plan to do ourselves and then have inspected. When setting up a new system, the idea of networking several parts of the house naturally comes up.

Which system or systems would you recommend based on the following requirements:
At the moment, I’m mainly considering Homematic, but that might be more suitable for retrofitting apartments. Other systems like KNX might be better, especially if the walls are already open 😉

Controlling roller shutters:

• Raise and lower via smartphone remotely. For example, raising four skylight shutters in case of hail.
• Lower all shutters in the house with one click on the phone (eight shutters).
• Automatically lower shutters at sunset and raise them at sunrise.

Controlling lights:

• Turn on the porch light in the evening, for example, even while on vacation.
• Turn bathroom and hallway lights on at half brightness during the night, but with the option to switch to full brightness if needed.
• Detect if a person is present in a room and automatically turn the light on and keep it on while they are there.

• Possibly even a linked mode between lights and shutters as a “shortcut”: Cinema mode — lights off and shutters down simultaneously.

Heating:

• Heat the living room only in the evenings on weekdays. This mode should be overridable on days off.
• Heat bathroom and kitchen only in the mornings and evenings.

Irrigation:

• Automatic, regular watering of vegetable beds in summer.

Alarm system / doorbell:

• Doorbell with automatic video feed to smartphone.
• Door and window sensors.
• Surveillance camera with cloud storage for footage.

Maybe some of these wishes are not practical or are actually quite simple to implement? Or do you have other suggestions for useful integrations that don’t require much effort?

Is it possible to estimate the costs for each item? Of course, the cheaper the better. I know that avoiding these features altogether is the cheapest option 😉 That’s why I’d like to prioritize if possible when estimating prices.

Thank you very much!

Best regards,
