ᐅ Is it possible to retrofit a central control system for roller shutters?

Hello everyone,
We have electric shutters throughout the house. Now we are considering whether to have a central control system offered and installed by the electrician right away or to do it ourselves later. The main issue right now is the 2500 EUR the whole thing would cost. This wasn’t budgeted and was actually intended for something else.
The electrician said the installation would be different. But I thought you simply connect timer switches instead of regular ones, and the built-in mechanism then controls my shutters based on the scheduled times. And at the central unit, everything comes together, where I can also control everything from one place, right?
Or am I misunderstanding this? I don’t really have any expertise in this area. We have 15 electric shutters, which should simply be centrally controllable now, but does it really cost 2500 EUR? Sure, there are 15 of them, but the central unit itself is supposed to cost only about 200–300 EUR. I understand the effort for the wiring, but is the installation really that different if the shutters themselves are already electric?
Thanks to all!

A deep electrical box can be quite useful. Additionally, there is sometimes the problem that not all connections are available at the actuator location. For example, with Homematic you need the neutral (“N”), which is not always present. If you go wireless, then do it properly right away and don’t wait one or two years.If you want a Homematic actuator and switch/button for each shutter, a standard deep 68mm (2.7 inches) box alone is not enough. The actuator either has to be installed in a second box or placed inside the shutter casing. This means that, for retrofitting, a conduit between the switch box and the shutter casing is required, as well as power supply including neutral wires provided at a different switch box.

Alternatively, you can use the Rademacher switch, which includes a timer and other functions. Everything can then be centrally controlled with a remote control or, if you use the HomeServer, from a smartphone or PC.
Retrofitting is quite straightforward. For example, using z-Z-Wave:
- 15 flush-mounted actuators at about €45 each.
- A central unit (I estimate €100-300), or alternatively a Raspberry Pi (~€130). You can then use this for all other automation tasks as well, so the cost is not only for the blinds.
This totals roughly €800. An astro function is usually included (I use OpenHab 2 with a Raspberry Pi, which allows control based on astro times directly, without extra costs).
Homematic is in a similar price range, but z-Z-Wave has the advantage of being non-proprietary, especially gaining strong traction in the USA market, with many manufacturers adopting it. Installation is easy.
