to counter point this post and your assumption that I am not smart - I use of home automation and smart devices extensively. I use Alexa, smarthings, z-wave switches, and various things.
1) "Alexa, turn on kitchen". Turns on the various light switches that are collectively the kitchen.
2) all things turn off at 11PM during the weekdays. Make sure that the various lights that were on get turned off.
3) When turning on the basement light switch it automatically turns on the lights in the utility room where the laundry is.
4) When turning on the basement playroom light switch, in turns on "all the lights in that room", because that's the common use case.
5) outside lights come on and turn off automatically
6) Christmas tree lights outside come on and off on a regular basis.
7) Inside christmas lights come on and off
8) Front door opens automatically and locks automatically based on kids schedule.
9) Custom key codes for the front door for contractors
10) "Alexa, announce dinner". Announces dinner everywhere in the house. really useful.
11) Nest goes to eco mode when no-one is in the house.
12) Lights turn on automatically in the kitchen when you get home.
etc etc etc. It all works and doesn't require much work. The mobile based alerts are the weakest link in the system as they don't always work.
