Powerwall-Dashboard

Monitoring Dashboard for Tesla Solar and Powerwall systems using Grafana, InfluxDB, Telegraf and pyPowerwall.

Animation Monthly Yearly Powerwall+ FreqVoltage Alerts Weather

Dashboards

The default dashboard.json shown above, pulls in live power data from the local Tesla Energy Gateway or the Tesla Cloud and displays that on the Grafana dashboard. A power flow animation is rendered by the pyPowerwall container using that live data.

A non-animated version of the dashboard is also available using dashboard-no-animation.json

Dashboard

Requirements

The host system will require:

  • docker (install help)
  • docker-compose (works with docker compose (v2) as well)
  • You should not need to run sudo to install this tool. See Docker Errors below for help.
  • TCP ports: 8086 (InfluxDB), 8675 (pyPowerwall), and 9000 (Grafana)

Setup

Clone this repo on the host that will run the dashboard:

    git clone https://github.com/jasonacox/Powerwall-Dashboard.git

Option 1 - Quick Start

Run the interactive setup script that will ask you for your setup details.

  cd Powerwall-Dashboard
  ./setup.sh

The dashboard can be installed in four different configurations.

  Powerwall Dashboard (v4.0.0) - SETUP
  -----------------------------------------
  Select configuration mode:

  1 - Local Access   (Powerwall 1, 2, or + using the Tesla Gateway on LAN) - Default
  2 - Tesla Cloud    (Solar-only systems or Powerwalls without LAN access)
  3 - FleetAPI Cloud (Powerwall systems using Official Telsa API)
  4 - Powerwall 3    (Powerwall 3 using the local Tesla Gateway)

Local Mode

For Powerwall 1, 2 or + owners with a Tesla Energy Gateway accessible on their LAN, select option 1 (Local Access).

Extended Device Vitals Metrics (beta)

With version v4.4.0+, pypowerwall can be set to access the TEDAPI API on the Gateway to pull additional metrics. However, it requires the Gateway Password (often found on the QR sticker on the Powerwall Gateway) and your computer will need network access to the Gateway IP (192.168.91.1). You can have your computer join the Gateway's local WiFi or you can add a network route (examples below). This should be set up before running setup.sh if you want this feature.

# Example - Change 192.168.0.100 to the IP address of Powerwall Gateway on your LAN

# Automatic - Route Script - Detect OS and setup persistent route.
./add_route.sh

# Linux / RPi - Add to netplan, /etc/rc.local or /etc/network/if-up.d/static-route for persistence 
sudo ip route add 192.168.91.1 via 192.168.0.100

# MacOS 
sudo route add -host 192.168.91.1 192.168.0.100 # Temporary 
networksetup -setadditionalroutes Wi-Fi 192.168.91.1 255.255.255.255 192.168.0.100 # Persistent

# Windows - Using persistence flag - Administrator Shell
route -p add 192.168.91.1 mask 255.255.255.255 192.168.0.100

Powerwall 3 Mode (beta)

If you have access to the Powerwall Gateway (see local mode Extended Device Vitals Metrics note above), you can select option 4 to activate Powerwall 3 mode. All data will be pulled from the local Gateway TEDAPI endpoint. If you have problems with your setup for the Powerwall 3, see troubleshooting section below.

Cloud and FleetAPI Mode

For Tesla Solar or Powerwall 3 owners without LAN access, select option 2 (Tesla Owners unofficial Cloud API) or option 3 (Tesla official FleetAPI) and the dashboard will be installed to pull data from the Tesla Cloud API. This mode should work for all systems but will have slightly less details and fidelity than the "Local Access" mode.

Timezone

Next, you will then be asked for your Local timezone, and your Powerwall details or Tesla Cloud login details. To find your timezone, see the second column in this table: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones

Troubleshooting

  • If you experience issues with your Powerwall or Tesla Cloud login details, re-run setup.sh to try again.
  • If you get docker errors during the setup, see the Docker Errors section below.
  • For Windows 11 users, see the Windows 11 Instructions below.

Grafana Setup

Follow the Grafana Setup instructions (see below) to complete the setup.

Option 2 - Manual Install

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

Note: some manual configuration is required if you are running a non-standard docker installation (e.g. rootless). Also, ensure that the conf, env and sql files are readable by the docker services (e.g. chmod 644).

You will want to set your local timezone by editing pypowerwall.env, telegraf.conf, influxdb.sql and dashboard.json or you can use this handy tz.sh update script. A list of timezones is available here: TZ Table.

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

Docker Containers

  • Copy pypowerwall.env.sample to pypowerwall.env and update the following details for your Powerwall:

        PW_EMAIL=email@example.com
    PW_PASSWORD=password
    PW_HOST=192.168.91.1
    PW_TIMEZONE=America/Los_Angeles
    PW_DEBUG=no

  • For Tesla Solar owners or Powerwalls without LAN access, to configure pyPowerwall in Tesla Cloud mode instead of Local Access mode, edit pypowerwall.env and leave the PW_HOST= setting blank. NOTE: Once the docker containers have started, an additional step is then required to login to your Tesla Account by running the command docker exec -it pypowerwall python3 -m pypowerwall setup.

  • Copy compose.env.sample to compose.env. You do not need to edit the other defaults unless you are running a non-standard install such as docker rootless or require custom ports.

  • Copy influxdb.env.sample to influxdb.env. You do not need to edit this file, however if you have a custom setup, environment variables can be added to override the default InfluxDB configuration.

  • Copy telegraf.local.sample to telegraf.local. If you want to monitor custom measurements for your site (most users don't need this), add the required telegraf.conf TOML entries to this file. Once created, this file is not overwritten by upgrades or future runs of setup.sh.

  • Copy grafana.env.sample to grafana.env - you do not need to edit these defaults. However, there are optional settings for alert notifications and HTTPS.

  • Optional: If you want to pull in local weather data, copy weather/weather411.conf.sample to weather/weather411.conf and edit the file to include your location (Latitude and Longitude) and your OpenWeatherMap API Key. To get a Key, you need to set up a free account at openweathermap.org. Make sure you check your email to verify account. API keys can take a few hours to activate.

        [OpenWeatherMap]
    # Register and get APIKEY from OpenWeatherMap.org
    APIKEY = aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
    # Enter your location in latitude and longitude
    LAT = xxx.xxxx
    LON = yyy.yyyy

  • Start the docker containers with the utility docker-compose script

      ./compose-dash.sh 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: It can take a while for InfluxDB to start. Also 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

Create Datasources

  • As of v4.5.0, the setup script will auto provision data sources for you. However, you can manually set them up as well by following these two steps:
  1. From Configuration\Data Sources add InfluxDB database with:
  • Name: InfluxDB
  • URL: http://influxdb:8086
  • Database: powerwall
  • Min time interval: 5s
  • Click "Save & test" button
  1. 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

Import Dashboard

  • From Dashboard\Browse select New/Import, and upload one of the dashboard files below (in dashboards folder):

    1. dashboard.json - Dashboard with the live trend graph, monthly power graphs, an animated power flow diagram and a Powerwall+ section that includes String data, temperature, voltage and frequency graphs. This also includes a "grid status" graph below the animation to identify and track grid outages.
    2. dashboard-no-animation.json - Similar to above but without the animated power flow diagram.
    3. dashboard-simple.json - Similar to above but without the Powerwall+ metrics.
    4. dashboard-solar-only.json - For Tesla Solar Only users, similar to above but without the animated power flow diagram or the Powerwall+ metrics.

Notes

  • The database queries are set to use America/Los_Angeles as the timezone. Remember to edit the database commands influxdb.sql with your own timezone. During import of dashboards into Grafana you'll be prompted to enter your timezone for queries.

Upgrading

  • The included upgrade.sh script will attempt to upgrade your installation to the latest Powerwall-Dashboard version without removing existing data. A backup is still recommended.

Troubleshooting Tips and Tricks

Check the logs of the services using:

  docker logs -f pypowerwall
  docker logs -f telegraf
  docker logs -f influxdb
  docker logs -f grafana
  • Docker terminating with error 139: InfluxDB does not run reliably on older models of Raspberry Pi.
  • Grafana Error: Invalid interval string, expecting a number followed by one of "Mwdhmsy" - This indicates that the Grafana setup for InfluxDB is missing the time unit, "s", in the "Min time interval" field:
    • Min time interval: 5s
  • PyPowerwall Error: If you are getting LoginError: Invalid Powerwall Login errors but have double checked your password and are sure it is correct, try using the last 5 characters of the password written on the Powerwall Gateway.

Missing Powerwalls or String data?

  • String data only shows up for Tesla inverters as part of Powerwall+ systems. Unfortunately, non-Tesla inverter data is not available via the Tesla API. If you find a way to pull this data, please submit an Issue or Pull Request to get it added.
  • The default dashboard and InfluxDB setup supports up to 12 Tesla Powerwalls. Support for more can be added by editing the dashboard.json and influxdb.sql files. Open an Issue and we can help (see #2).

Docker Errors

If you are getting permission errors running docker, or an error that it isn't installed:

  • Ensure docker is installed for your OS (run docker version to test)

  • If you see permission denied, add your user to the docker group and reboot your system:

    # Add your user to docker group
sudo usermod -aG docker $USER

  • If the above step hasn't worked, and you get an error trying to run docker info like permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock:

    # Grant permissions to the docker daemon socket
sudo chmod 666 /var/run/docker.sock

  • If you can't access the dashboard after a reboot, that means that docker was not set to start on reboot. On many OS distributions you can set it to start on boot with:

    # Set docker to start on boot
sudo systemctl enable docker.service
sudo systemctl enable containerd.service

  • See Docker install here for more information.

  • If you have docker installed but get "ERROR: docker-compose is not available or not running" make sure it is in your PATH or if needed, install the docker compose tool:

    # install - for Ubuntu and Debian, run:
sudo apt-get update
sudo apt-get install docker-compose-plugin

# install - for RPM-based distros, run:
sudo yum update
sudo yum install docker-compose-plugin

# test
docker compose version

Savings Errors

The savings estimates are based on a $0.19/kWh (by default) utility cost and net metering credit. You likely have a different value for this and during importing dashboards indicate your average cost per kWh to reflect your actual costs and credits. As of now there's one variable to set both cost and credit per kWh. To help, here are the variables used to calculate the savings:

  • s = kWh from solar (based on time frame selected)
  • fp = kWh from powerwall
  • tp = kWh to powerwall
  • tg = kWh to grid

The equations that are used to compute the estimated savings:

  • powerwall>home = fp * $/kWh [assumes all power to home from PW = savings]
  • solar>home = (s - tp - tg) * $/kWh [assumes all solar not going to PW or grid is going to the home = savings]
  • solar>grid = tg * $/kWh [assumes all power going to grid = savings]

Synology NAS and Rootless Docker

  • If you are having trouble getting this to work on a Synology NAS, view the resolution discovered in Issue #22 thanks to @jaydkay.
  • If you are running docker as a non-privileged (rootless) user, please some setup help here thanks to @BuongiornoTexas.
  • Most of the issues running the Dashboard on Synology NAS are related to user or file permission issues. Ensure that the conf, env and sql files are readable by the docker services (most can be set chmod 644).

Windows 11 Instructions

Installing Powerwall-Dashboard on a Windows 11 host requires some additional setup. Install and Setup using administrator PowerShell or Windows Command Prompt:

If required, see WINDOWS.md for notes on how to upgrade your WSL installation from WSL1 to WSL2, or for an installation without Docker Desktop - only recommended for very advanced users.

  • (optional) install Windows Terminal Windows Terminal
  • Install WSL wsl --install with a Linux distro (recommend Ubuntu - this is the default WSL Linux distro if you install with wsl --install)
  • Install Docker Desktop for Windows Docker Desktop (after install, note sign in is optional, and to ensure the docker engine starts automatically go to Settings and select Start Docker Desktop when you log in)
  • Start your WSL from the shortcut for Ubuntu (or your chosen distro) that will have been set up when you installed WSL or from Windows Terminal
  • Make sure you are in your home directory cd ~
  • Clone repo (git clone https://github.com/jasonacox/Powerwall-Dashboard.git)
  • Run cd Powerwall-Dashboard
  • Run ./setup.sh

Powerwall 3

The new Powerwall 3 does not have the local APIs that were found on the Powerwall 2/+ systems. However, it does provide APIs available via its internal Gateway WiFI access point at 192.168.91.1. If you add your Powerwall 3 to your local network (e.g. ethernet hardwire) or create a WiFi bridge to this access point, you are able to get the extended metrics from the /tedapi API. Additionally, users can use the "Tesla Cloud" mode to generate the basic graph data. It is more limited than the local APIs but does provide the core data points. See details in the Powerwall 3 Support issue: https://github.com/jasonacox/Powerwall-Dashboard/issues/387

Some have reported issues setting up their Powerwall 3 and the local 192.168.91.1 access point. Make sure that this IP address is reachable from the host running the Dashboard (e.g. ping or curl commands).

Since the Powerwall 3 does not have previous generation APIs, you will need to use the full TEDAPI mode. This requires that the PW_EMAIL and PW_PASSWORD environmental variables are empty and that PW_GW_PWD is set to the Powerwall 3 Gateway WiFi password (usually found on the QR code on the Gateway itself).

Example of a working pypowerwall.env file for Powerwall 3:

PW_EMAIL=
PW_PASSWORD=
PW_HOST=192.168.91.1
PW_TIMEZONE=America/Los_Angeles
TZ=America/Los_Angeles
PW_DEBUG=no
PW_STYLE=grafana-dark
PW_GW_PWD=<YOUR_PW3_PASSWORD>

Tips and Tricks

Since pyPowerwall proxy is part of this dashboard stack, you can query it to get raw data (read only) from the Powerwall API. This includes some aggregate functions you might find useful for other projects. I use this for ESP32 driven display for example. Replace localhost with the address of the system running the dashboard:

Since weather411 is part of this dashboard stack (if you set it up) you can query it to get current weather data from its built-in API.

Data Retention and Backups InfluxDB is configured to use an infinite retention policy (see influxdb.sql). It uses continuous queries to downsample Powerwall data and preserve disk space. However, this does not safeguard the data from accidental deletion or corruption. It is recommended that you set up a backup plan to snapshot the data for disaster recovery. See backups for some suggestions.
