Reading unknown patterns/data with the minion

[Hampus Kensing]

I have some radio circuit breakers at home and if I remember correct they run at the same frequency as my minion.

It would be a nice home automation project to have the minion send the switch command to these circuit breakers. I have no idea what signal the remote sends of if it is even possible for the minion to mimic it.

Any idea how I'd go about to eavesdrop on the remote with the minion and print the "raw" data to the serial console?

interesting idea.  so it would be using the minion as a wifi sniffer.  i'd love to be able to do this as well.

This project sound like a solution to your radio sniffing idea

http://jeelabs.net/projects/cafe/wiki/NRfMon_-_nano_Spectrum_Analyzer_with_the_RFM12B

 A software spectrum analyzer for the RFM12B transceiver module running in a JeeNode or an Arduino. Use this program to visualize what the RFM12B transceiver module "hears" in the 433, 868 or 915 MHz bands.

nRf Mon tries to visualize what's happening on the radio waves when transmitting and get an understanding of the physical qualities involved. Based on an idea that initiated in the JeeLab forums, a sample sketch and JeeLib, it provides a basic spectrum analyzer with a waterfall display along with normal frequency and time domain displays of the signals, as they are heard by the very same RFM12B module employed in the board.

This tool is written in the Tool Command Language, TCL, a great scripting language for developing such utilities. It is accompanied by a sketch, which must to be uploaded to the Jeenode or whatever Arduino or compatible board the RFM12B module under test is connected to. The source code can be found here: https://github.com/dzach/nrfmon . This project is also discussed in the JeeLabs forum thread nRfMon - RFM12B forensics .
