Re: I already have an IoT standard
Look out of your windows and generally you'll be able to get a good idea of what the days weather will be.
But not so good for forecasting how the weather will be in the coming days, and sometimes not even the afternoon.
Technology does have its uses, betters poking one's head out the cave and waggling a finger in the air.
As for smart thermostats and the like; I don't see the point. I set my thermostats and tweaked my radiator valves a decade ago and have never changed them.
