I do not have a home so perhaps I do not fully understand. If it is warm when I go to bed, I turn on the ceiling fan by rotating the knob next to the bed. When I wake up, I turn it off. What kind of automation are you looking for?
Another use-case I have for this is in a house where the mezzanine gets much warmer than below when heating during winter: detect this with a couple of temperature sensors and turn the fan on when needed.
I also really like automatically adjusting the brightness/color temperature of all our lights during the day.
It’s by no means necessary, but I don’t want to go back now.
Also, I've maybe seen a speed control knob for a ceiling fan a few times in my life in the US. Here it's all pullchains, or more recently "smart" bullshit.
