What does this consist of? Is it an open source project? I would love to set up something like this, but I constantly find myself not having the time.

- throwaway2016a 10y agoHome grown. Node.js running on a server in my basement. I do plan to open source it someday. It was a lot of work. Some devices I had to reverse engineer.[1] [1] A little more detail on that because I'm sure they might find it interesting: - If there is a phone, Linux, or Mac app I use Charles to try to intercept the traffic - If that fails I use Wireshark - If that fails I decompile their app - If none of those work, I have to ditch the hardware and try new hardware.

They're generally dual band, operating at WiFi frequencies for local interaction and with more power at a lower frequency for the networked traffic. While the protocols are not intended to be WiFi compatible, the already-proven-hackable devices are just a patch away from unexpected functionality. The local link is intended for things like telling your air conditioner not to run part of the time when the grid supply doesn't have much excess capacity. What other data is sitting around? How about raster images of whatever your "copier" printer fax has handled? Even if you're using USB, if there's WiFi capability in there, assume it can be awakened. A link that's not compatible with your sniffer is a possibility too. Drag out a spectrum analyzer and directional antenna. While you're at it, check those new LED streetlights for bursts of r.f. too.
