Re: ... IoT devices generally have no real world advantage over their dumb counterparts ...
I've been thinking the same. I came up with some very niche luxuries, but nothing life-changing.
- Preemptive heating: Check the weather forecast and act accordingly.
- The 'house is empty' button. Press to turn off all lights, sound systems, games consoles and TVs, and reduce heating. Checks with the front door too - if the door doesn't confirm proper closure within one minute, texts you to remind you to close it.
