I live in a bungalow.
I can see the 'east wing' (or Mini-Me Mk 1s bedroom as it's otherwise known) from the hallway, much like I can see every other room in the house from the hallway. if I look out of any of the windows into the back garden I can check for the shed, office, garage, and workshop to see if they have any lights left on.
I don't need a smart meter, I simply need a small amount of mobility to check on things.
Clearly you are not a moron.
