The thing is that I am thinking about having one, but
a) I don't run the MAX! software itself
b) I want to take my own actions when pressing the button, which is not necessarily entering the eco mode for all thermostats (which seems to be the function of the button in the MAX! software).
Perhaps someone can shed some light on this and check?
So what I would like the button to do is....nothing

And also, can more than one button be used?
