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 two 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)

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

For Tesla Solar owners or Powerwalls without LAN access, select option 2 (Tesla Cloud) and the dashboard will be installed to pull the data available from the Tesla Cloud API. This mode works for Solar Only and Powerwall 3 owners, but will not provide all the details or fidelity that the “Local Access” mode offers.

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

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.

Follow the Grafana Setup instructions provided (or 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
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\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

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 currently provide a customer accessible API on the local network. Work is ongoing to determine if there is a way to get the rich set of data that is available directly from its predecessors (Powerwall 2/+). In the meantime, users can use the “Tesla Cloud” mode to generate the basic graph data. See details in the Powerwall 3 Support issue: https://github.com/jasonacox/Powerwall-Dashboard/issues/387

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:

pyPowerwall stats: http://localhost:8675/stats
Powerwall firmware version and uptime: http://localhost:8675/api/status
Powerwall temperatures: http://localhost:8675/temps
Powerwall device vitals: http://localhost:8675/vitals
Powerwall strings: http://localhost:8675/strings
Powerwall battery level: http://localhost:8675/soe
Key power data in CSV format (grid, home, solar, battery, batterylevel): http://localhost:8675/csv

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.

Current stats of weather411 service: http://localhost:8676/stats
Current conditions: http://localhost:8676/
Current conditions in JSON: http://localhost:8676/json

Data Retention and Backups InfluxDB is configured to use a 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 recommend that you set up a backup plan to snapshot the data for disaster recovery. See backups for some suggestions.
