Manual install (FreeBSD)

This document provides the necessary steps for installation of TeslaMate in a FreeBSD jail. The recommended and most straightforward installation approach is through the use of Docker, however this walkthrough provides the necessary steps for manual installation in a FreeBSD 13.0 environment. It assumes that pre-requisites are met and only basic instructions are provided and should also work in FreeBSD before 13.0.

Requirements

Click on the following items to view detailed installation steps.

bash & jq
pkg install bash jq
bash

For simplicity reasons, follow the rest of the tutorial in bash rather the csh.

git
pkg install git
Erlang (v21+)
pkg install erlang
Elixir (v1.12+)
```bash pkg install elixir ```
Postgres (v14+)
pkg install postgresql14-server
pkg install postgresql14-contrib
echo postgres_enable="yes" >> /etc/rc.conf
Grafana (v8.3.4+) & Plugins

The latest Grafana from ports/pkg has a startup issue with the rc script, starting via rc.local is the workaround.

pkg install grafana8
echo grafana_enable="yes" >> /etc/rc.conf
# Only needed if grafana fails to start via rc.conf
echo "cd /tmp && /usr/local/etc/rc.d/grafana onestart" >> /etc/rc.local
An MQTT Broker (e.g. Mosquitto)
pkg install mosquitto
echo mosquitto_enable="yes" >> /etc/rc.conf
Node.js (v16+)
pkg install node
pkg install npm-node

Clone TeslaMate git repository

The following command will clone the source files for the TeslaMate project. This should be run in an appropriate directory within which you would like to install TeslaMate. You should also record this path and provide them to the startup scripts proposed at the end of this guide.

cd /usr/local/src

git clone https://github.com/adriankumpf/teslamate.git
cd teslamate

git checkout $(git describe --tags `git rev-list --tags --max-count=1`) # Checkout the latest stable version

Create PostgreSQL database

The following commands will create a database called teslamate on the PostgreSQL database server, and a user called teslamate. When creating the teslamate user, you will be prompted to enter a password for the user interactively. This password should be recorded and provided as an environment variable in the startup script at the end of this guide. Use 'su - postgres' if unable to enter psql console from current user.

psql
postgres=# create database teslamate;
postgres=# create user teslamate with encrypted password 'your_secure_password_here';
postgres=# grant all privileges on database teslamate to teslamate;
postgres=# ALTER USER teslamate WITH SUPERUSER;
postgres=# \q

Note: The superuser privileges can be revoked after running the initial database migrations.

Compile Elixir Project

mix local.hex --force; mix local.rebar --force

mix deps.get --only prod
npm install --prefix ./assets && npm run deploy --prefix ./assets

export MIX_ENV=prod
mix do phx.digest, release --overwrite

Starting TeslaMate at boot time

Create FreeBSD service definition /usr/local/etc/rc.d/teslamate

Update /etc/rc.conf

echo teslamate_disable_mqtt="true" >> /etc/rc.conf
echo teslamate_timezone="<TZ Database>" >> /etc/rc.conf #i.e. Europe/Berlin, America/Los_Angeles

Start service

chmod +x /usr/local/etc/rc.d/teslamate
service teslamate start

Import Grafana Dashboards

  1. Visit localhost:3000 and log in. The default credentials are: admin:admin.

  2. Create a data source with the name "TeslaMate":

    Type: PostgreSQL
    Default: YES
    Name: TeslaMate
    Host: localhost
    Database: teslamate
    User: teslamate Password: your_secure_password_here
    SSL-Mode: disable
    Version: 10
  3. Manually import the dashboard files or use the dashboards.sh script:

    $ ./grafana/dashboards.sh restore

    URL: http://localhost:3000
    LOGIN: admin:admin
    DASHBOARDS_DIRECTORY: ./grafana/dashboards

    RESTORED locations.json
    RESTORED drive-stats.json
    RESTORED updates.json
    RESTORED drive-details.json
    RESTORED charge-details.json
    RESTORED states.json
    RESTORED overview.json
    RESTORED vampire-drain.json
    RESTORED visited.json
    RESTORED drives.json
    RESTORED projected-range.json
    RESTORED charge-level.json
    RESTORED charging-stats.json
    RESTORED mileage.json
    RESTORED charges.json
    RESTORED efficiency.json
    tip

    To use credentials other than the default, set the LOGIN variable:

    LOGIN=user:password ./grafana/dashboards.sh restore
