Dockerized dbus playback + mqtt service

Use this docker to run an mqtt broker that serves recorded dbus data. Main use case would be to run this instead of having a real Venus GX device or VenusOs running in a raspberry pi, making local development work much easier but also more realistic. The container can run different configurations (different sets of devices connected to it) of the VenusGX by running different sets of recordings with a simple commandline api.

Usage

  • Install Docker
  • Create container with ./build.sh
  • Run the container as an interactive shell with ./run.sh
    • run ./start_services.sh within the container to start the mqtt and other services.
    • run ./simulate.sh <simulation> to start playback.
  • Run the container in the background with a simulation with ./run.sh -s <simulation_name>
    • to kill the container (and to remove it because of the --rm option) use docker kill <container id>
    • get the container id from the output of the run script or with docker ps
    • multiple can be run in parallel in which case the ports are incremented and printed by the script
  • For more info run ./run.sh -h

Additional arguments

Additional arguments you can pass to simulate.sh or run.sh include:

  • --with-solarcharger: Add a solarcharger to the simulation
  • --with-pvinverter: Add a pvinverter to the simulation
  • --with-tanks: Add tank sensors to the simulation

Working inside the container

You can see what data is available in the mqtt by using mosquitto_sub -t N/# or use an mqtt spy application. To change values manually use mosquitto_pub, but these values are likely to be overridden by an active recording quite quickly.

Modifying recordings

Recordings can be modified with the following steps:

  1. Get the recording desired as a tsv file: ./get_recording_tsv.sh <simulation>. Simulation must be a simulation in ./simulations/X/<simulation>.dat
  2. Edit acquired tsv
  3. Recompile the simulation and replace local simulation file with ./recompile_and_replace_simulation.sh <edited_simulation>.tsv <simulation> where <simulation> must be the same simulation file as in step 1

Systems (simulations)

Battery selection should always be on auto; unless specified differently.

A) Absolut Navetta 68 installation

2 x Skylla-i chargers 2 x VE.Bus Phoenix Inverter 24/3000 (230V and 120V for USA) 1 x BMV-700

And a few more devices, but they won't be connected to Venus:

1 x Phoenix charger 24/25 (for engines) 1 x BlueSmart 12/30 IP22 (for generators) Which electrical parameters can be monitored with these machines? (device by device) Is it possible to set alarms or change device functions via the interface with Garmin?" AC Input 1 & 2 settings are (probably) to be configured as not available; we'll find out once we start working on the gui-overview for this.

Using venus-docker with a real Venus device

  • On the Venus device, edit your /etc/ssh/sshd_config to allow remote connections to forwarded ports:

    GatewayPorts clientspecified

  • Restart openssh to make the above take effect:

    svc -t /service/openssh

  • On the venus device, stop mosquitto:

    svc -d /service/mosquitto

  • On the machine that hosts the venus-docker setup, start a venus-docker simulation as you normally would.

  • Forward the port to the venus device using ssh. Note the leading ::

    ssh -R :9001:localhost:9001 root@192.168.22.75

  • Browse to the web application: http://192.168.22.75/app

Building dbus-spy

A binary copy of dbus-spy is already included in this repo, but should you need to rebuild it, these are the steps:

git clone git@github.com:victronenergy/dbus-spy.git
cd dbus-spy
git submodule update --init
cd ..
docker build -f dockerfile.dbus-spy . -t dbus-spy

Then copy dbus-spy out of a throwaway container by first starting a container:

docker run -it --rm dbus-spy

Then copy dbus-spy to bin:

docker cp <container>:/usr/local/bin/dbus-spy bin/dbus-spy
