wmbusmeters/docker

wmbusmeters

The program receives and decodes C1,T1 or S1 telegrams (using the wireless mbus protocol) to acquire utility meter readings. The readings can then be published using MQTT, curled to a REST api, inserted into a database or stored in a log file.

Running the wmbusmeters container

Pre-requisite

Before running the command that creates the wmbusmeters docker container, you must add udev rules to create usb device symlink in order to have persistent link to device across host restarts and reconnect usb device:

cat <<EOF > /etc/udev/rules.d/99-wmbus-usb-serial.rules
SUBSYSTEM=="tty", ATTRS{idVendor}=="10c4", ATTRS{idProduct}=="ea60", SYMLINK+="im871a", MODE="0660", GROUP="docker"
SUBSYSTEM=="tty", ATTRS{idVendor}=="0403", ATTRS{idProduct}=="6001", SYMLINK+="amb8465", MODE="0660", GROUP="docker"
SUBSYSTEM=="usb", ATTRS{idVendor}=="2047", ATTRS{idProduct}=="0863", SYMLINK+="rfmrx2", MODE="0660", GROUP="docker"
EOF

For RTLSDR symlink passing to docker image is not working due to fact that rtl_ binaries are looking for full usb bus path in system to identify device. Full usb bus path should be passed to docker --device=/dev/bus/usb/002/117 for example and in wmbusmeters config file device=auto should be changed to device=rtlwmbus

Command line container download and run

docker run -d \
    --name=wmbusmeters \
    --restart=always \
    -v /etc/localtime:/etc/localtime:ro \
    -v /opt/wmbusmeters:/wmbusmeters_data \
    --device=/dev/im871a \
    weetmuts/wmbusmeters 

Command line Options

Parameter	Description
--name=wmbusmeters	Names the container "wmbusmeters".
--restart=always	Start the container when Docker starts (i.e. on boot/reboot).
-v /etc/localtime:/etc/localtime:ro	Ensure the container has the correct local time.
-v /opt/wmbusmeters:/wmbusmeters_data	Bind mount /opt/wmbusmeters (or the directory of your choice) into the container for persistent storage that will contain configuration and log files.
--device=/dev/im871a	Pass the device at ttyUSB0 into the container for use by wmbusmeters (you may need to change path to your device ).

Specify device in configuration file if wmbusmeters does not find device by changeing device=auto to device=/dev/im871a for example.

If you are using docker-compose.yml file you may also copy/paste the following into your existing docker-compose.yml, modifying the options as required (omit the version and services lines as your docker-compose.yml will already contain these).

version: "2"
services:
  wmbusmeters:
    image: weetmuts/wmbusmeters
    container_name: wmbusmeters
    restart: always
    volumes:
      - /opt/wmbusmeters:/wmbusmeters_data
      - /etc/localtime:/etc/localtime:ro
    devices:
      - /dev/im871a

Then, you can do docker-compose pull to pull the latest weetmuts/wmbusmeters image, docker-compose up -d to start the wmbusmeters container service, and docker-compose down to stop the wmbusmeters service and delete the container. Note that these commands will also pull, start, and stop any other services defined in docker-compose.yml.
