> There's a reason why you won't find any useful smart coffee machine on the market. Sure! It's expensive to shove a bunch of smart technology into every single device, especially given that everyone wants something a little different so your interface would need to be feature-rich to support those use cases. Note that we don't really care about having a smart coffee machine in the outlined scenario; we need a coffee machine that can be preheated, which doesn't have to be any more complicated than a switch on the power supply on the right dumb machine. > And your house knowing where your keys are is either so specific a scenario that it's useless or contents of fantasy science fiction. With off-the-shelf software it's a mix between the two. The hard bit wouldn't be the location of simple objects like keys (throw a few sensors around the house, customize the final layer on a pre-trained model, and pick your favorite approximate inverse-3d mapper to get a rough location in space of the object); it would be the location of complicated objects (house, where's my Lang's Algebra?), cases where you don't have enough information but would hope that the house might figure it out (e.g., boxes of things), and the humanistic output (rather than saying they're on the bedside table, you might have to resort to a screen that can show locations of things on a heatmap). > You will probably need to assemble your own lamps That was a communication error on my part.

I'd be tempted to hook into Google Calendar or something for upcoming trips since they've already implemented models to find that kind of thing, at least starting out, but otherwise I see no reason you'd want to use proprietary software in a project like that.
