So… thanks to this my dad had one place left from all the searched places to look for his keys: The area. And keys are back with my dad. Laundry voilà What’s next? This tool is not a stuff-locator-tool, there’s a lot of things that could be done with all this data of my house being logged and this is where the next part begins: applying techniques to try to predict what is going to happen next in my house so it decides on it’s own what’s best to do without being programmed to do it, like learning to turn on a light when walking in a dark aisle. Artificial Intelligence I’ll keep you updated. Cheers.
