Is there a solution for a Somfy interface?
Somfy has a similar solution to EnOcean (Smoove UNO io + SKK potential isolation relays - potential-free
contacts which are wirelessly controlled by the I/O Homecontrol), but this is not a bidirectional solution. The
MACO E-Hardware can thus only be controlled, but cannot provide feedback on its position. However, such a
positional feedback can be implemented using the MACO mTronic.
If we use KNX or LON for control, but do not have an Aumüller ventilation station available, can we then
connect to our interface? Does our circuit diagram then work?
In this case, the connection is done with an additional power supply. A potential-free actuator must be used,
which switches the MACO e-hardware according to the circuit diagram. Again, this is not a bidirectional
solution. The e-hardware can only be controlled, but cannot give a notification on its position.
Generally, the following drive positions can be reported
(but only with an Aumüller control panel and KNX connection):
Window was tilted by motor,
Window was closed by motor,
where applicable, window was moved to turn position by hand.
In no case is there a notification on where the window is actually positioned – whether it has been tilted
or closed by hand. This is due to the fact that the drive always returns to the zero position and there are
no magnets over the entire hardware and thus no position recording. Only the last position actuated by
the drive can be reported.
