- remote control to turn on/off lights in bed
- Bed sensor to turn on/off lights when heading to the bathroom at night
- define a scene (lights dimmed, shades down, mood lights on) to trigger in an event (Netflix turned on TV at 8pm)
- Remote control of wall AC unit out of the house (shut off while away but turn on before driving home)
- Alerts for when my brother turns on the coffee maker
- Control system to avoid coffee maker and microwave running together long enough and tripping the circuit breaker in your old apartment (haven't done this one)
- Alert to tell you when washing machine is done (or use to estimate how much time is left)
- use color lights as reminders or to signify events
- check to make sure doors are closed and locked at night
- check that door for room (or window in room) with AC is closed when AC is running, otherwise shut AC off
- alerts when someone gets home even if you are out of the house (know kid gets home from school, for example)
Ultimately it is a hobby. I had a raspberry pi 4 I bought and had just sitting around. It feels good to see it in the corner doing something cool.
