Switch module for remote RS3

[Calf 1]

Dear All,

 

I'm retrofitting some rollers and my constraint is that there is no cabling between the rollers and the wall switches. This means that the wall switches will use the Z-Wave network to communicate to the RS3 on the rollers (which have no wires on their Sx input). 

 

Additionally, since all switches/plugs in the apartment are from Feller, and in order to respect the look-n-feel, I don't want to install some 3rd party Z-Wave switches that would look differently. As such, I'm going to install Feller Roller buttons on the wall, such as those:

The question I have is: what Fibaro module should I install behind those Feller switches? Should I also install RS3 behind them (which means that for the 2-rollers Feller 7594.AV.FMI.61, I'd need to find a way to pack TWO RS3 in the wall, each communicating with their remote RS3 counterparts outside on the rollers). Or should I use another (cheaper?) Fibaro module?

 

Lastly, Feller proposes two different versions of their Roller Switch: one only lets the current flow only while we press on a button (conact) while the other let the current flows once the button has been pressed (interrupt), i.e.

I'd love your input on those two points. Thanks in advance.

Just to close the loop on this one. I ended up installing Fibaro RS3 behind the switches (which means 2xRS3 when I had a double Feller switch). This means that the RS3 behind the switches had no load wired, only the switches, and the remote RS3, the ones attached to the blinds, were not wired to any switches, they were only wired to the load (i.e. the motor). Obviously, you can only calibrate the RS3 attached to the motors, the other RS3 (behind the switches) couldn't be calibrated, but that's fine. I ended up setting a value for the up/down course that was about the one that the RS3 got calibrated to, but with a slight 5-10s buffer (higher is ok, lower might not be, I didn't try playing with that). The original firmware wasn't great, so it had all kind of kirks on how to stop the blinds once they were going in a given direction, but the newer version improves this behavior. So it is a bit costly (2xRS3 for each endpoint), but it works smoothly.
