Windows Installation Details for WSL1 to WSL2 and No Docker Desktop

Upgrading WSL1 to WSL2

If you have previously tried out Windows Subsystem for Linux (WSL) on Windows 10, you may have the original WSL1 version installed.

For many reasons, you probably want to upgrade from WSL1 to WSL2.

To upgrade, you need to be running at least version 1093 of Windows 10 - you can check by running winver

If you happen to have installed WSL to play around, and have an old version around, you might want to update the version of that installed distro (but, then again, it might be an old distro, so that might not be the best idea; if it doesn't have anything useful, you might be better of starting with a brand new, up to date Ubuntu distro).

In any case, the best way to get the core WSL2 components installed, and updated is

  wsl.exe --install
  wsl.exe --update

To then check if you have any WSL 1 distros installed, you can run the wsl -l -v command that will show you the version of any distros

NAME      STATE           VERSION
* Ubuntu    Running         2

If any are running version 1, you can upgrade them to version 1 with wsl --set-version <distro-name> 2, for example wsl --set-version Ubuntu 2

Running without Docker Desktop

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 Powerwall details and Local timezone. To find your timezone, see the second column in this table: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones.

  cd Powerwall-Dashboard
  ./setup.sh

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

  • Copy compose.env.sample to compose.env - you do not need to edit these defaults unless you are running a non-standard install such as docker rootless.

  • 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.

Notes

  • The database queries are set to use America/Los_Angeles as the timezone. Remember to edit the database commands influxdb.sql and powerwall.yml 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 cli tool: 
    # install
sudo pip3 install docker-compose

# 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).
