some automations / scenes I have
when leaving - "hey Siri, goodbye" - turns off all the lights, TVs, and stops music playing
or "goodnight" turns off all the lights, TV, closes the shades, turns on the bedroom ceiling fan and air filter.
at sunset, if I'm not home, turns on some light for the cat.
when I get home and open the door - starts music, turns on lights and opens the shades (different lights/shades depending on if it's night or day) music is also different later at night.
have a ceiling fan in the bedroom, made a "dummy thermostat" for it, it will adjust the fan speed based on room temp.
under cabinet lights in the kitchen trigger on a motion sensor, but only if everything is off, so it gives you light to see. and different levels depending on day or night.
Adjust AC thermostat depending on if I'm home or not.
And have an automation/shortcut that triggers when I leave work, it checks the temperature at home, and if it's over 78, it asks if I want to turn on the AC.
have a thru-wall AC (like a window unit). When the TV turns on, it sets the AC fan to low
button by the bed, short press will turn on enough light to see to get to the bathroom and kitchen. Long press turns off all the lights.
notification if the front door opens and I'm not home.
My mom passed last year, house was unoccupied for about year while we dealt with everything. got a couple door sensors, lamp modules, cameras, and a HomePod mini, Was nice to get door notifications, see inside the house, and turn lights on/off so it looked occupied. All from 1500 miles away.
