I absolutely refuse to bother with some sort of "Home" setup which depends upon WiFi and one or more devices to control things. I am perfectly capable of getting up out of a chair and manually turning on a light or adjusting the thermostat to my liking without grabbing my iPhone!
I agree that having to use for phone for certain tasks is a PITA.
But I have a whole-home lighting control system (Lutron) and I rarely have to even touch switches.
All outdoor lights are timed. They come on at Dusk and off at 1AM.
Indoors I used a variety of timers with conditionals and occupancy sensors to turn on/off 90% of the lights.
For example, beside the garage there is a Keypad and the bottom button Is labeled AWAY. The last person to leave the house presses this button which tells the lighting control system to NOT turn on the Indoor timed lights. But as soon as the garage door is opened, that cancels the command and if it is past Dusk, the Living Room lights come on so we can walk into a lit house.
Another example is my wife stays up later than me so she has a GOODNIGHT button on a keypad in the Living Room. When she presses is a few things happen: all lights in public areas go OFF except the Living room lamps. They stay on for 2 more minutes. The light in the bathroom comes on at 15% so she can find her way in without it being pitch black. She then turns those off with a nightstand keypad.
One other example is we have a hot water circulation pump. Turn on any of the bathroom lights or kitchen lights and the pump circulates for 5 minutes to make sure there is hot water as soon as you turn on the tap.
I wouldn't want to live without it.
As for Thermostats, I use a Nest, but rarely touch it. It is programmed to do what we want and does well 98% of the time.
