There was quite a flurry of threads here regarding smartmeters recently,
so people might be interested in my recent tinkering with them ...

As someone who works on this sort of thing there is no way you ever encrypt
stuff that is transmitted between components on the same board (or from
mother to sister board). This just isn't a "normal" risk case.

The data being snooped has been received from the electricity meter over
868MHz by the daughter board, I am working on the assumption that the
daughter card just receives "packets" and slings them to the main board
for processing. Out of the box there is a pairing process between meter
and display, so it's possible that stores a key in the PIC's EEPROM.

Ah 868, I was wondering which of the many bands the RF chip could
operate on was working. Thats within the coverage of DVB-T USB stick
receiver, if we ever get a smart meter I might snoop the RF like I
may do with the various 433 MHz stuff I have here.

You might find a USB TV receiver dongle useful for that, by using it as
an SDR (software defined radio). Lookup SDRSharp.
