I wrote drivers to read the US NOAA weather--so I get colored lights for rain/snow/storm&tornado watches/warnings. Plus some announcements for tornado warnings.
When I unlock my doors, they recognize the person by the code and greet the person. And, turn on the lights, unlock the desired inside doors.
When I go to bed, one button turns off all the lights, arms the alarm, locks all the doors.
When I open the bedroom door to go to the restroom at night--it brings the lights up to dim. When I then shut it, they slowly go off after a minute.
I can set "alarms" that start by slowly brightening the lights--then every 10 minutes, start making different sounds once a minute (clicks, ding-dongs, then "get your butt out of bed"
).
When I leave, I tap a button that opens the garage door. When I shut the garage door, it arms the system & turns off all the lights.
When I open outside doors, the outside lights get brighter (at night).
My outside lights come on at sunset/off at sunrise. Inside lights rather randomly come on and go off to mimic when I'm home.
I have a virtual "vacation mode" switch. When on, the HVAC uses warmer/colder temps to save money. The water heater is turned off. When the alarm is enabled, the water valve is shut off
In addition to the weather colors, during holidays, the outside lights show special colors.
If I want to chill on the patio with a fire in the firepit, I tap a button on the way out the door and it dims the lights so they are perfect for that.
I have a tic-tac-toe game (I wrote the driver for that, too) on my chimney. Anybody with a link to the dashboard can play it.
I have a special dashboard for my emergency contacts. They can type a message and it will blast across my speakers. For emergencies when I'm sleeping and my phone is off (of course, my doofus friend blasted my butt out of bed early one morning for s&gs-- I was PISSED).
And more.
