Hi ..
I have been developing my own home controller for heating .
But now i must make my system bigger ..
Then i had thoughts of how to communicate between these units should work .
Is XIN and Xout between units a good way of doing it ??
Or should i chose serin and serout for this ...
I am planning to make one "master unit" and one in-module and some
out-modules.
Does anyone have some advice ??
