Looking for a sanity check

[scoobydrvr]

After getting everything set up with this application and some fumbled starts, I think I've gotten everything running but I haven't received any messages from my meters after ~3 days of logging. Can someone please make sure I'm not missing them and they just aren't being decoded?

General setup:
Raspberry Pi 4b with Nooelec RTL-SDR v5; collapsible antenna measured to 0.329 m (full-wavelength at 912 MHz); all hardware is on the other side of the wall from electric and gas meters in garage.
rtl_tcp is running in one window using sudo rtl_tcp with output matching the gifs in the setup docs
rtlamr is running in another window using sudo ~/go/bin/rtlamr -msgtype=scm,scm+,idm | tee -a output.txt (the pipe into tee is just so I can see things are still being received/decoded while putting them into a file to search later).

Meters:
Gas - Itron 100G DLS; FCC ID: EWQ100GDLAS (found on lines 57 and 65 of "ERT Modules" compatibility sheet)
Electric - Aclara I-210+c; FCC ID: OWS-NIC511-06 (not found in sheet but "-3" is for the same company in a different region)
Water - Sensus FlexNet 2W; unable to find FCC ID (searching leads me to believe this is encrypted and can't be decoded)

While I'm receiving a lot of traffic from a handful of meters in my vicinity, I don't seem to be capturing anything with the IDs printed on the labels of my meters. The utilities here are monopolized, so everyone gets services from one company for each - this leads me to believe everyone has the same hardware and I should be able to get messages from my own meters but, as stated, their IDs aren't present in what I've captured.

Any ideas what might be going on here and have I set up everything correctly?

Following up on this for future posterity - I have been receiving receiving messages from 65 different gas meters in my area. My personal meter ended up being an SCM+ meter and the ID matched what is printed on the label; I'm not sure how I missed it...

I still haven't received readings from my electric or water meters. My electric reading resets on the 15th of the month so I'm hoping it's a situation where it wakes up and transmits. From what little I can find, it appears the water meter is encrypted - not sure there's much of anything I can do about that...
