I started with Home Assistant a while ago.

I have a door sensor on the front door and a Button to set a boolean, when I took the meds.

If i go out the door at a certain timespan (getting to Work) I immediately get a loud and annoying notification on my Phone.

Works perfectly, and I can't live without it.

I also have my alarm turning on a light, which helps wonders for getting up in the morning.

And a alarm, if I left a window open because I'm forgetting about that regularly.
