Why my meters aren't sending any data?

[reypm]

I’ve installed the latest version of rtlamr2mqtt and configured the add-on as shown below:

general
sleep_for: 60
verbosity: debug
device_id: "0"
rtltcp_host: 127.0.0.1:1234
tickle_rtl_tcp: false

mqtt:

ha_autodiscovery_topic: homeassistant
ha_status_topic: hass/status
base_topic: rtlamr
user: mqtt_user
password: <redacted>
ha_autodiscovery: true
tls_enabled: false

custom_parameters:
rtltcp: ""
rtlamr: ""

meters:
- id: 79263328
  protocol: scm
  name: electricity_meter
  unit_of_measurement: kWh
  icon: mdi:meter-electric-outline
  device_class: energy

  protocol: r900
  name: water_meter
  unit_of_measurement: gal
  icon: mdi:meter-water
  device_class: water
  state_class: total_increasing

The add-on starts successfully, and the logs indicate it’s connecting to the MQTT broker and publishing configurations (see below). However, no meter readings appear in the logs. Is this expected behavior? What could I be missing?

I've started having this issue after updating to Debian 12. Worked great on 11 then stopped on 12. I hoped with the new version it would work, but still doesn't I'm using another addon canned Acurite to Home Assistant that uses another rtl dongle and it still works. Other RTL based addons work, but this one previously was the best as far as what I needed and I hoped to stick with it.

[allangood]

I don't see any meter reading on your output.

[reypm]

well, in a test I made for you here there was reading, not sure why it does not work now, but I guess it's related to the frequency: Tuned to 100000000 Hz.

[allangood]

I can't see what is the output for the RTLAMR. The frequency is set by it.
This is a sample output:

After the 2025.6.1 update, my logs now look like this:

The Tuned to 100000000 Hz. line just repeats and my meters never update.

I have the same problem. It worked before 2025.6.1

Same issue here. I made the necessary config adjustments to device ID the replacing the mqtt address 127.0.0.1 to get it talking again, but it just idles on 'Tuned to 100000000 Hz.' Tried loading the CenterFreq and other variables into the rtlamr parameter in config to see if it could see my meter again, but didn't seem to have an effect. Wound up rolling back to 2.3.4

[allangood]

After bringing my laptop to my old neighborhood, I could reproduce the problem.

I am tracking the issue here:
#277

[reypm]

@allangood is this fixed in the latest release? I am still unable to get any data from my meters. Here are the logs:

[gitdanny20]

Hey @allangood, I am facing the same issue and I believe my configuration is correct (I was previously able to read data from this meter in older versions). Is it possible that bug #277 did not fully resolve the issue?

For additional context, I am attempting to connect to a Neptune R900+ water meter using this adapter.

I have installed the latest version of the HA Add-On.
