Help in the roller shutter control jungle

I wrote that for 1600€ ADDITIONAL COSTS he gets KNX for the WHOLE house I did not write that he gets KNX for the house for 1600€ !!!!!!!

He did write that he spends 1,600 euros ONLY for rolling shutters down in the evening and up in the morning !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Well, is the OP or his brother really capable of setting up their own interface with the PI?

The software still has to be purchased and someone also has to do the programming. If you can do it yourself, all the better, otherwise the costs will be added.

It's just a bit more expensive and complicated than described. ;-)

If the OP only wants to control the blinds, there are certainly other systems that are cheaper and easier.

Pi is an option, otherwise just the USB interface. And the demo is free. It is limited to 5 devices per project. 4 actuators and 10 switches, so that makes 3 projects. Otherwise, the ETS Light can do 20 devices per project and costs €200.

But honestly, before I spend €1600 just for the blinds to go up in the morning and down in the evening, I’ll look at KNX. And the note that his brother is an electrician suggests that he does some of his own electrical work. Which again speaks in favor of KNX. And anyone who claims KNX is difficult or complicated hasn’t really looked at it yet. I assert that ANYONE who can handle Excel can also manage it with ETS.

I was recently at a friend’s who has KNX in his house (since 1994). Over the past years he kept having the electrician change things. I sat down with him for an hour and showed him what ‘HIS’ electrician had done for him over the years... He was almost stunned. Since then, he has activated a lot of ‘NEW’ functions in his house. He just said if he had known earlier what all is possible as standard and how simple it actually is... (And no, he is not a computer scientist)

I don’t want to push anyone’s opinion here but it just annoys me that everyone claims KNX IS EXPENSIVE and KNX is COMPLICATED.

KNX is simply different. And especially when comfort functions come into play, unbeatable in flexibility and in that case also no more expensive than doing it classically. Just the fact alone that I no longer have a mess of switches on the wall. If there is heating, lighting, and 3 blinds in the room, classically I already have at least 5 switch boxes!!! With KNX you only need one. And I don’t have to run 5 NYM cables there (1x light, 1x heating, 3x blind) but only one bus cable.

@Neill: it would be nice if you could say what is easier and cheaper.

: sorry for the ! but you apparently helped.

Just as info how it is with me.
Roller shutter functions:
Central
Up in the morning, down in the evening, central down/up (36 roller shutters).
Ground floor up/down, upper floor up/down

Zones
(Shading) South, East, West, North.
Dining/Cooking/Living/Sleeping

Scenes.
Watching TV in the evening different roller shutters than at midday (living room windows in the south and west).

Control roller shutters by room,
Control individual roller shutters.

If one or more of the terrace doors are open these roller shutters stay up until the door is closed (even if central down or automatic evening roller shutter down). When the door is closed the roller shutters go down.
Ventilation function. If window is tilted and roller shutter is down the roller shutter is raised to 90% (slats open).

What I invested for this. Atom PC with 64gb SSD and logic/visualization Edomi (150€) 4 actuators from BMS (1200 Euro) 5 8-channel glass push buttons from MDT (650€) which are also used for scenes and lighting. Window contacts (25€/window) which BMS has digital inputs that can be used for the window contacts.

The wiring is also simpler because you only have to lead the NYM cables from the roller shutter to the distributor. (For me 18 cables on the ground floor and 18 cables on the upper floor). Alternatively you can run with a NYM cable from roller shutter to roller shutter but then the BUS cable must also be looped through and you install the actuators decentrally. You have the terminal point next to the roller shutter anyway.

The bus cable can have any topology which means it can be pulled crisscross through the house. Everything except ring is allowed. That also makes it easier to retrofit something later.

Maybe someone can write what they paid for a classic roller shutter control. Surely there are some who have electrified roller shutters.

You have drifted quite far by now...so please back to topic
