• 2.0.6-dev: OZW 1.6.962

Here there are 3 different way to start the container and provide data persistence. In all of this solutions remember to:

1. Replace /dev/ttyACM0 with your serial device
2. Add -e TZ=Europe/Stockholm to the docker run command to set the correct timezone in container

docker run --rm -it -p 8091:8091 --device=/dev/ttyACM0 --mount source=zwave2mqtt,target=/usr/src/app/store robertslando/zwave2mqtt:latest

Here we will store our data in the current path ($(pwd)) named store. You can choose the path and the directory name you prefer, a valid alternative (with linux) could be /var/lib/zwave2mqtt

mkdir store
docker run --rm -it -p 8091:8091 --device=/dev/ttyACM0 -v $(pwd)/store:/usr/src/app/store robertslando/zwave2mqtt:latest

To run the app as a service you can use the docker-compose.yml file you find on github repo. Here is the content:

version: "3.7"
services:
  zwave2mqtt:
    container_name: zwave2mqtt
    image: robertslando/zwave2mqtt:latest
    restart: always
    tty: true
    stop_signal: SIGINT
    networks:
      - zwave
    devices:
      - "/dev/ttyACM0:/dev/ttyACM0"
    volumes:
      - ./store:/usr/src/app/store
    ports:
      - "8091:8091"
networks:
  zwave:
# volumes:
#   zwave2mqtt:
#     name: zwave2mqtt

Like the other solutions, remember to replace device /dev/ttyACM0 with the path of your USB stick and choose the solution you prefer for data persistence.

In 1.0.0 version all application data where stored inside the volume. This could cause many problems expectially when upgrading. To prevent this, starting from version 1.1.0 all persistence data have been moved to application store folder. If you have all your data stored inside a volume zwave2mqtt this is how to backup them:

APP=$(docker run --rm -it -d --mount source=zwave2mqtt,target=/usr/src/app robertslando/zwave2mqtt:latest)
docker cp $APP:/usr/src/app ./
docker kill $APP

This will create a directory app with all app data inside. Move all files like OZW_log.txt zwscene.xml zwcfg_<homehex>.xml in app/store folder and use that folder as volume following this section

If you get the error standard_init_linux.go:207: exec user process caused "exec format error" probably it's because you previously installed a wrong architecture version of the package so in that case you must delete the existing volume that contains the old executable:

docker volume rm zwave2mqtt

Check files inside volume

docker run --rm -it --mount source=zwave2mqtt,target=/usr/src/app robertslando/zwave2mqtt:latest find /usr/src/app

Delete Volume

docker volume rm zwave2mqtt

Docker images contains latest stable images of zwave2mqtt repo. If you want to keep your image updated with latest changes you can build it on your local machine. Just select a commit and replace existing commit in Dockerfile here

git clone https://github.com/robertsLando/Zwave2Mqtt-docker.git
cd Zwave2Mqtt-docker
sed -i "s|<actualCommit>|<newCommit>|g" Dockerfile
docker build -t robertslando/zwave2mqtt:latest .

Build just the build container

docker build --target=build -t robertslando/zwave2mqtt_build .

docker run --rm -p 8091:8091 --device=/dev/ttyACM0 -it --mount source=zwave2mqtt,target=/usr/src/app robertslando/zwave2mqtt:latest sh

docker run --rm -p 8091:8091 --device=/dev/ttyACM0 -it --mount source=zwave2mqtt,target=/dist/pkg robertslando/zwave2mqtt_build sh
