For gr-smart_meters itself, and the RECESSIM Gr-smart_meters_Setup_Guide.
My base system is Debian testing (Bookworm) gnuradio 3.10.4.0 and gr-osmosdr 0.2.3.
Maybe a little bleeding-edge at the moment, but it (or something very similar) should go mainstream in a matter of months.
The setup instructions are based on gnuradio 3.8 or 3.9, and don't work as-is on 3.10.
As discussed in https://lists.gnu.org/archive/html/discuss-gnuradio/2022-12/msg00074.html I needed to
apt-get install --no-install-recommends libsndfile1-dev
before starting to build the OOT gnuradio modules.
Skipping over gr-osmosdr (because there's a Debian package),
- gr-pdu_utils
- gr-sandia_utils
- gr-timing_utils
- gr-fhss_utils
all need to have their maint-3.10 branch checked out, and get built and installed in the above order.
I got some compile-time build warnings; logs available on request.
I needed to
add apt-get install -y gobject-introspection gir1.2-gtk-3.0
before gnuradio-companion will start up, otherwise it complained about "Namespace Gtk not available".
I suppose most people wouldn't notice, if they have some default Ubuntu desktop loaded. I personally find such X environments unusable. :-(
About gr-smart_meters proper, and examples/GridStream_RTLSDR_NoGUI.grc in particular:
- It self-identifies as
id: GridStream_HackRF_NoGUI. This leads to it confusingly generating GridStream_HackRF_NoGUI.py when you press gnuradio-companion's Generate button. - Running it crashed with an invalid FFT size. I changed fft_size value: int(2000) to int(1024), and that let it run.
All of this is possibly a waste of my time. I looked more closely at my electric meter.
I have a California PG&E Landis+Gyr FOCUS AXRe-SD, and the sticker at its top says ITRON, FCC ID: OWS-NIC511-06; no mention of GridStream.
Thanks! While the GridStream block might not be helpful in decoding your smart meter the whole flow graph may be. If you look at messages output with a Message Debug block prior to the PDU Align block you'll see any transmissions in the ISM band.
You can then determine which messages might be from your meter and set a custom PDU Align value to target them.
As for the other information on installation I have been meaning to update for GR 3.10. The latest dev branch has quite a few changes as well. I also like Conda for installing and managing the environment.
I'll update the wiki soon to make it clearer, thanks a lot for taking the time to document your process.
Updated the Wiki Instructions, will have to test with a fresh install of Ubuntu to verify.
Dev branch addresses the example flowgraph issues you pointed out. Will push that to main soon, again appreciate your detailed feedback.
