Ya, I like that idea. I’ve thought about the possibilities, and have wanted to get one for other things too, but just haven’t had enough time to sink into that kind of project yet.
When I do eventually get around to tinkering with some kind of Raspberry Pi or Arduino or something like that, I will indeed try to incorporate this need into the mix, but in the mean time, I’m focusing on more ready-made solutions.
There are things like the BlueKangaroo devices (LINK1, LINK2)
They’re not available yet (CrowdFunding), and I’m not totally sure if this will be possible with it when it’s ready for the marketplace, but that’s just an example. If there are other similar products, I will be considering them as well as I move forward with this.
Then, there’s also the idea of involving some of the Androids (Bluetooth and WiFi) that are and will be mounted on walls all over my house to run SmartTiles, LANnouncer, etc.
