Hello everyone,
we are currently building our single-family house with a general contractor. Our quote includes electronic roller shutters and venetian blinds. The offer also includes one switch planned for each roller shutter or venetian blind. However, we are not entirely satisfied because there is no option to lower all the roller shutters and venetian blinds at once. Currently, I see the following solutions:
1) One central switch per floor (basement, ground floor, upper floor) that lowers all the roller shutters/venetian blinds on that level. According to the electrician, this is complicated to implement and quite expensive (about 1000 euros per switch plus wiring).
2) Each roller shutter/venetian blind is equipped with an actuator (is that the correct term?), which we can control wirelessly. In other words, everything operates with switches, but I have the option to send a wireless signal to all roller shutters so they go down or up together.
3) Electric wireless drives are used (e.g., Somfy Rs 100 io). Then no wired switches would be needed for the drives. However, I would have wireless switches stuck to the whole wall. Is that really practical?
I’m sure there are clever solutions I haven’t thought of… Can you help me?

You have a Tahoma box and those are wireless switchesI'm really confused.
According to the delivery note, I have item no. 1811272, which is the "Central switch Smoove Origin IB (for wired roller shutter motors)."
However, I have also noticed that I still have 3 out of 4 unused "Radio socket module Animeo RTS 1860105" here (which are no longer available under this item number from Somfy).
What is going wrong here?

Besides the Tahoma Box, do you have another control unit or possibly Somfy switches (Smoove UNO IB+) directly connected to the blinds? It seems to me that your central switch only sends a signal to the individual blind switches, meaning you would need to program the blinds at the blind switches themselves. I’m not very familiar with the Somfy system, so this is just a guess.

I’m not very familiar with the Somfy system, so this is just a guess.I have this "central switch" as a push button in every room—don’t ask me why it’s called a central switch.
I can program the blinds at the push button regarding this "my position," meaning that pressing "my" moves the blind to a previously saved position.
My problem, however, is that when I access the Tahoma box’s web interface via browser, I don’t find any blinds listed in the menu. There are only tabs for io or RTS, but no ib, see below 🙁

AllThumbs16 Apr 2021 13:51The main issue seems to be that the Tahoma Box only supports wireless protocols, while you have a bus-based, wired system.
The operation is actually illustrated quite well in the two images below. Each switch for an individual roller shutter initially controls only that specific shutter. The individual switches are connected via the bus line to the central switch. This allows the central switch to command the switch to operate the roller shutter without manual activation.
I haven’t quickly found any external system that can be connected to the IB bus. This seems to me to be a very niche solution from Somfy?
