A short list of items on timer at the house:
a) Dehumidifier. For some reason, it tends to cycle on/off a lot when it's near the target humidity. Annoying during the workday in the basement office. I called the manufacturer - no way to adjust the hysteresis. So I picked up a heavy duty timer to keep it off during the day, when it switches on at night (when electricity is less in demand, anyway) it runs longer but less annoying cycling.
b) Fan in yoga room. Switches off mid-morning before the day gets hot, stays off all day (preserving the cooler night air in the house) and switches back on in teh early evening.
c) Front porch - I have a programmable switch that turns the porch light on and off automatically.
One of these days I'll pick up a whole house controller, and really geek it out. But not today....
