ᐅ Bus system / Home installation, seeking advice and cost planning

Hello

I am interested in a bus system for our new single-family house.

What should I consider during the planning phase?
How much does such a system typically cost?
Where can I find information about installation and related details?

Thanks for many answers

For the size of your house, the cost will likely be in the range of EUR 20,000 to 25,000 (around USD 22,000 to 27,000) – possibly more depending on the scope.

Your electrician should be able to provide you with a quote and may also recommend a service technician from the preferred system or supplier for further explanations. I have just organized such a presentation for one of my clients with a Siemens technician. Nowadays, the technology – in this specific case an EIB/KNX system – is becoming increasingly complex, so it makes sense to have a professional explain everything in detail.

If you are interested in home automation, in my opinion it also makes sense to integrate an alarm system or at least prepare the installation for it.

Kind regards

How much exactly? Wow. Considering how "simple" these systems are designed, that price is outrageous.
Just to be clear, a bus system means something like: automatically controlling the heating, automatic blinds, lighting control, webcams, networking the house, all controllable via tablet or web?
Or am I mistaken? Is there more to it?

By the way, if you are planning to equip your house with Miele@Home products: stay away. They are no good. We have them in use at the university in a smart home test lab. From an IT standpoint, they do what they are supposed to, but unfortunately, they are hardly useful for cooking.

hi,

so I was also very interested in EIB.
the initial estimates were around 20,000 euros.

but once you implement the basic functions—the ones I can also achieve with a conventional installation—we ended up with a total of about 9,000 euros.

already significantly less than the initial estimates, but still too expensive for us.

I think it can be done more cheaply or differently.
Ask for a quote on the cost if the wiring for the lights is installed individually and continuously back to the distribution panel. The switches as well.
Have them install impulse relays there.
Also, run the sockets on a multi-core (wires) cable that leads to the distribution panel.

Additionally, install an empty conduit through each room (DIY), so you are prepared for the future.
With this setup, you can gradually upgrade the electrical installation to a BUS system.

I will soon start renovating a house and will also install a BUS system (I am an electrical master technician). For me, the complete electrical installation (material only) for a 155 m² (1670 sq ft) house including the BUS system, switches, socket materials, distribution panel, and wiring will cost around 7,000 to 8,000 euros. Installation will be done by myself. I will be using the HomeMatic system.

How much, please? Wow. Considering how "simple" these systems actually are, the price is outrageous.

Or am I completely off base here? Is there more to it?

It’s like in life: the smaller the sales volume, the higher the unit cost.

The problem here isn’t (just) the material cost of the components, but the incredible fees the electrician demands for planning and configuring the installed components...

They act as if it’s extremely complicated, while with some technical understanding you can learn it yourself in a short time...

And the worst part is that every time you want to make a change, you have to call the electrician again, who then charges €200 (about $215) just to tweak one byte... -.-

My advice: buy the ETS software yourself (costs around €1000 or about $1075) and do the configuration on your own... that way you can make changes anytime yourself when you want to add new sensors or fix something in the old program...
