A Home Assistant automation that watches your bedroom temperature all night and adjusts the ceiling fan speed automatically — so you never have to touch it again.

Once you've set up an automation to turn lights on and off, you'll find that sometimes that's not what you want.  You may prefer to have the lights simply stay on.  Here is an easy way to do that without interacting with the dashboard or using voice prompts.

So you've installed Home Assistant and it's working.  Great, but it doesn't do very much yet.  You probably don't have a lot of smart home devices lying around.  Or do you?
