It appears everyone in the area has a 100G DLS I setup RTL AMR and listend for quiet some time and had no messages. I'm assuming that must mean it's encrypted and it won't pick anything up. I tuned my tuner in and watched and there is a bunch of chatter unfortunately it lines up with z-wave and I have many z-wave devices.

Any ideas on if picking up usage from encryption is even viable?

so I analyzed and found data on frequency 926.41 at 2359300 Hz just going to turn gas on and watch to see for changes. The pulses over a couple minute period were very repetitive.

Found a few meters but in 30 hour period I haven't gotten a duplicate of the same ID. If I scan the frequency I get pretty consistent tags in RTL_433. Sensitivity issue?

It sounds like you don't have any ERT-compatible meters in your area. It's common to see some spurious messages over the span of a few hours, eventually random noise will look like a valid packet.

There are two likely reasons you won't hear from your meter: it's configured for wake-up instead of bubble-up, meaning it doesn't regularly transmit unless asked to; and second, it doesn't have an ERT-compatible transceiver despite being a meter that usually has one.

I was able to get a packet one time from my meter in a 30 hour period. It matched my consumption displayed on the physical meter but that was the only time I got it. I'm assuming this must mean it is setup for wake-up. Anyway to ping it now that I know the address to poll?
