@noxx Yes you have to change the code from homeduino, but thats not very easy. Its easier to use a second arduino and create your own sketch which has 2 digital ins that you control with homeduino.
thats not what i want to hear
i thought its easier. i´m not a programmer.
is there a change to add this in homematic by one
of the programmer? i mean a official release with motor shield support!
