1. An automation system for automating an adjustable shading device on a window in a room, said automation system including:
a. first temperature-determining means to determine a first temperature closer to the temperature of said room than to the temperature of said window;
b. second temperature-determining means to determine a second temperature closer to the temperature of said window than to the temperature of said room;
c. first processing means to produce a difference signal which varies with said second temperature minus said first temperature;
d. second processing means to produce an integral signal which varies with the time-integral, over an interval, of said difference signal; and
e. a controller to adjust said shading device to a shading setting which depends on said integral signal.
