About fans, wipers and blinds

A common experience in summer is to switch the fan on and go to sleep in the night. As the night gets colder, the fan wind turns from comfort to discomfort of chill.

Similar discomfort happens when it starts raining and you start the wiper at certain speed – and then at a traffic light, you stop. The wiper gives screeching sound.

How many times did we keep blinds at certain position in the noon and then switched lights on too early in the evening?

While there are air conditioners and smart windshield wipers for those ready to spend a fortune, I think there should be cheaper way – through a simple feedback loop.

Apart from increasing comfort, such controls can save power very significantly by running a fan slower, wipers slower and opening blinds depending on the day light.
