HAOS add-on listen mode

[TimTechToo]

I have the rtlamr2mqtt add-on installed in my HOAS RPi 4 with the nooelec dongle and I am having a hard time understanding the "I don't know my meters ID, what can I do?" section of the GitHub page. Since I'm not running docker, the stated instructions do not work for me. How do I retrieve all the meter IDs broadcasting in my general area? I don't understand the Instructions "run the container in DEBUG mode". Researching DEBUG MODE leads to a lot of other issues trying to get it to run in HAOS. All I have done so far is install and run the add-on. Pasting <docker run --rm -ti -e LISTEN_ONLY=yes -e RTL_MSGTYPE="all" --device=/dev/bus/usb:/dev/bus/usb allangood/rtlamr2mqtt> into Terminal results in "bash: docker: command not found". Can someone please guide me to obtaining my smart meter IDs?

I went to HomeAssistant settings, Addons, rtlamr2mqtt, configuration and changed the "listen_only: false" to true. Then I went to http://homeassistant.local:8123/config/mqtt and put "rtlmar/debug" into the "listen to a topic" section and "start listening".
I now see entries showing up every few seconds.
I see my water meter s/n in the output.
Message 21 received on rtlamr/debug at 1:35 PM:
{"Time": "2024-07-28T13:35:48.350594265-04:00", "Offset": 0, "Length": 0, "Type": "R900", "Message": {"ID": 1577759290, "Unkn1": 163, "NoUse": 37, "BackFlow": 0, "Consumption": 13584, "Unkn3": 0, "Leak": 0, "LeakNow": 0}}
QoS: 0 - Retain: false
Now to grab the associated data and get it to feed into the energy dashboard.
I put this in my rtlamr2mqtt config:

• id: 1577759290
  protocol: scm+
  name: meter_water
  format: "####.###"
  unit_of_measurement: gal
  icon: mdi:water
  device_class: water
  state_class: total_increasing

However, trying to "add water source" to my energy dashboard gives me a "No matching statistics found"

I'm making progress but I'm stuck again. I would appreciate any insight.

Hi TimTechToo - you wrote " I now see entries showing up every few seconds."

Where do you see these entries?

[TimTechToo]

After you "start listening", scroll down and you’ll see the listen output. I kind of missed it until I scrolled the page down.

[TimTechToo]

I changed the protocol to r900 and the format to #####.# and the "add water source" recognized the meter data. The USD/gal entry had to be changed to 10 times my actual cost. I think this is because the USD/gal multiplier multiples the raw consumption data instead of the payload data sent to MQTT.
My Energy dashboard is working now but I am keeping an eye on it and see if it needs massaging. I have a lot of old erroneous data that is polluting my graphs. I am trying to find a way to purge the old data and start fresh.
