That would be a dumb home then. A smart home would be properly insulated and a lot more passive, it wouldn't leak as much heat and wouldn't be cold when you get home. All without "smart" tech or burning extra fossil fuel.

The “smart” tech is affordable and costs less than renovating or rebuilding a home, a luxury which many people cannot afford.

Did you run the numbers on savings with insulation vs using "smart" tech?

Usually, it's only a matter of time before insulation pays for itself, the time being roughly a decade. Still, people would rather limp along rather than fix it up.
