Itron 500G stopped working

[m0sia]

Hi,

I have a Itron 500G gas meter and it was working fine for more than a year. Suddenly at 2am in the morning of November 2, 2023 I stopped receiving any reading from it as well as any of the neighbors' readings.

At first I was blaming the SDR dongle and even bought a new one, but it did not help. Does anyone have an idea what happen? I haven't changed anything with my setup.

what was your setup for reading it? I wonder if it got switch to only broadcast on demand?

Frankly nothing unique.

I have RTL2832U + R820T2 USB dongle. Initially I started with rtlamr on my MacBook figuring out what I can receive and then I had it running with rtl_433 docker container dumping sensor readings into MQTT/HA.

After it stopped working I tried the following:

• Bought a brand new SDR dongle
• Tried both latest rtlamr and rtl_433 both on Linux and MacOS in different locations across the house
• Tried running both on different central frequencies with 1MHz step from 902MHz to 928MHz
• Checked spectrum analyzer if there is any interference and there is none
• Checked spectrum analyzer and I can see some signals in 900MHz band that are not decoded. Not sure if they are from the gas(Itron 500G), electricity(Itron I-210+C) or water(Badger Read-o-Matic) meter
