We aren't too far in. Wife has an Echo Show 15 mounted to the wall in the kitchen to watch TV or listen to music while cooking. Has also been used to tell Alexa to add things to our shopping list or look up recipes, start a timer, ingredient substitutions, or ask Google facts just to prove me wrong.
Then we have Echo dots in the den, living room, bathroom, and bedroom. There is a Nest thermostat for the furnace. Smart bulbs in two lamps in the living room, one floor lamp in the sitting room, and lamps in all three bedrooms. Can set programs to turn lights on and off when we aren't home. My wife can tell the furnace to heat up while we are still driving home. I use Alexa to dim the lights when watching TV. Wife has a set up that turns off all of the lights and turns down the thermostat five degrees when we say, "Goodnight Alexa."
What I just added last week is a Smart wifi timer switch to the wall heater in the bathroom. I can sit in my recliner and start to feel the urge to go make a transaction. I can tell Alexa to turn the heater on for 10 minutes and have a nice warm throne when I go.

I like it so much, I am looking at installing another heater in in our other 1/2 bath. It's the one I use in the mornings we go to work.
I think next will be a few outside cameras.
