Powerwall_Monitor

Monitoring Dashboard for the Tesla Powerwall using Grafana, InfluxDB and Telegraf.

NEW LOCATION

This fork has materially changed from the original and is now hosted in a new location.

Previous

Dashboard Strings

This is based on the great work by mihailescu2m but has been modified to use pypowerwall as a proxy to the Powerwall and includes solar String graphs for Powerwall+ systems.

Requirements

The host system will require:

  • docker
  • docker-compose

Setup

Clone this repo to your local host that will run the dashboard:

    git clone https://github.com/jasonacox/powerwall_monitor.git

Quick Start

Run the interactive setup script that will ask you for your Powerwall details and Time Zone data.

    ./setup.sh

Jump to the Grafana Setup below to complete the setup.

Manual Install

If you prefer, you can perform the same steps that setup.sh performs.

You will want to set your local timezone by editing powerwall.yml, influxdb.sql and dashboard.json or you can use this handy tz.sh update script. A list of timezones is available here.

  # Replace with your timezone
  bash tz.sh "America/Los_Angeles"

Docker Containers

  • Edit powerwall.yml and look for the section under pypowerall and update the following details for your Powerwall:
            PW_PASSWORD: "password"
            PW_EMAIL: "[email protected]"
            PW_HOST: "192.168.91.1"
            PW_TIMEZONE: "America/Los_Angeles"
            PW_DEBUG: "yes"
  • Start the docker containers
    docker-compose -f powerwall.yml up -d

InfluxDB

  • Connect to the Influx database to import setup commands:
    docker exec -it influxdb influx -import -path=/var/lib/influxdb/influxdb.sql

Note: the influxdb.sql file is set to use America/Los_Angeles as timezone. Use the tz.sh script or manually update the database commands above to replace America/Los_Angeles with your own timezone.

Grafana Setup

  • Open up Grafana in a browser at http://<server ip>:9000 and login with admin/admin

  • From Configuration\Data Sources add InfluxDB database with:

    • Name: InfluxDB
    • URL: http://influxdb:8086
    • Database: powerwall
    • Min time interval: 5s
    • Click "Save & test" button

  • From Configuration\Data Sources add Sun and Moon database with:

    • Name: Sun and Moon
    • Enter your latitude and longitude. You can use this web page to find your GPS location if you don't know).
    • Click "Save & test" button

  • From Dashboard\Manage (or Dashboard\Browse), select Import, and upload dashboard.json

Notes

  • The database queries and dashboard are set to use America/Los_Angeles as the timezone. Remember to edit the database commands influxdb.sql, powerwall.yml, and dashboard.json to replace America/Los_Angeles with your own timezone.

  • InfluxDB does not run reliably on older models of Raspberry Pi, resulting in the Docker container terminating with error 139.

Troubleshooting Tips

Check the logs of the services using:

    docker logs -f pypowerwall
    docker logs -f telegraf
    docker logs -f influxdb
    docker logs -f grafana
