I finally got the my RPI RFM12 module to receive. Sadly my problem turned out to be a poorly soldiered connection on the module. Ooops.
I am now receiving data, but I am confused about the format of the incoming data. I can tell the first number if the node ID, but what is the rest? It doesn't look like my emonTx data since the numbers aren't even close. I can tell the node 15 entries are the time, but what is the rest? I am using minicom on the Raspberry pi to look at the data.

Re: Data from RPI RFM12B
Can't find any documentation about the format.
Look around here for the decoding part.
Re: Data from RPI RFM12B
The first byte is the Node ID of the sender, followed by a series of integers (2 byte); the meaning of these values depends on the sending node, i.e. could be temperature, light level, humidity, voltage, etc etc etc;
Check for the multinode concept here http://openenergymonitor.org/emon/emonBase/NanodeRF
The RFM2Pi is simply a gateway, it doesn't understand the relayed data; it simply passes it on to emoncms, where you are expected to know what you are processing.
