- bumby 5y agoI guess the question is really the upside/downside ratio. I think for many the upside is marginal compared to the potential downside.

- rileyphone 5y agoOr maybe our problems and potentials are radically different than they were 200 years ago?
- iratewizard 5y agoSpoken like someone toiling away at something your great-grandpa had a solution for.
- lazyasciiart 5y agoActual grandma tech: keep grandma at home using the oven so the house is warm when you get home.
- klyrs 5y agoNah, my grandma had a life, as I fully intend to when I'm her age.
- sjg007 5y agoI have never found this feature useful. In cold places you tend to leave the heat on to keep things stable. Same when it is hot and humid.
- konschubert 5y agoYou can turn down the heat a few degrees when you’re out of the house and save quite some energy this way.
- sjg007 5y agoNot really, not where I live.
- trompetenaccoun 5y agoThat 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.
- lotsofpulp 5y agoThe “smart” tech is affordable and costs less than renovating or rebuilding a home, a luxury which many people cannot afford.
- labawi 5y agoDid 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.
- Vetch 5y agoA smart system would learn your patterns and eventually be able to predict your arrival, setting a temperature that's further away from ambient and towards some target the more confident it is. Or a tad bit more risky, you could email it.
- wruza 5y agoCurious if that saves any significant energy, if you visit home regularly. The same with summertime AC. I believe that allowing a properly insulated room to get hot/cold and then reheating/recooling it takes the same work, because half a day is barely enough for it to get equilibrium with the environment. For a week probably yes, but then again you don’t want your home to cross a freezing point too often. Am I right or naive here?
- jaclaz 5y agoYou are half-way right (or half-way naive, it depends on points of view). Generally speaking (but it depends greatly on the specific home thermal properties and on the kind of heating or AC you have) it is usually less energy intensive to keep in winter your home at a certain temperature (lower than normal but not too lower) than to switch off completely heating and then when you get home boost to the wanted temperature.
- jaclaz 5y agoMany years ago I knew someone (an electrical engineer by trade) that modified a standard/ubiquitous Panasonic telephone answering machine connecting it to his home thermostat, he used the code to hear messages to switch the heat on. You don't need the internet, nowadays the equivalent would most probably be something like : https://www.ezyswitch.co.nz/ https://www.ezyswitch.co.nz/
