Power Dash

🚧 Work in Progress 🚧

This project is currently in Early Alpha. Features may change, and bugs are to be expected.

Power Dash is a modern, self-hosted dashboard and automation platform for the Tesla Powerwall. It acts as a high-performance bridge to your local gateway, collecting high-frequency data and presenting it in a beautiful, responsive interface.

✨ Features

• ⚡ Real-Time Monitoring: Live visualization of power flow (Grid, Home, Solar, Battery) with sub-second updates.
• 🔋 Comprehensive Data: Tracks Battery SoE, String Voltages, Inverter Health, and Grid Frequency/Voltage.
• 💾 Embedded Storage: Built-in, high-performance time-series database (Prometheus TSDB). No external database required.
• 🚀 Modern UI: Fast, responsive frontend built with React, Mantine, and uPlot for smooth zooming and panning.
• 🔌 API Proxy: Securely proxies requests to the Powerwall API, handling authentication and session management.
• 📥 Historical Import: Migration tools to import your existing data from InfluxDB (from Powerwall-Dashboard).

🛠️ Tech Stack

• Backend: Go 1.25+ (Gin, Cobra, Viper, Zap)
• Frontend: React 19, Mantine UI, Vite
• Database: Embedded Prometheus TSDB

🚀 Getting Started

Self-Hosting Options

Method 1: Docker (Recommended)

docker run -d \
  --name power-dash \
  -p 8080:8080 \
  -v ./data:/data \
  -e POWER_DASH_PASSWORD="YOUR_GATEWAY_PASSWORD" \
  ygelfand/power-dash:latest

Method 2: Docker Compose

A docker-compose.yml is included in the repository:

POWER_DASH_PASSWORD=YOUR_GATEWAY_PASSWORD \
POWER_DASH_ENDPOINT=https://192.168.91.1/ \
docker-compose up -d

Or set the values directly in docker-compose.yml and run docker-compose up -d.

Method 3: Standalone Binary

Download the appropriate binary for your operating system from the Releases page.

chmod +x power-dash
./power-dash run --password "YOUR_GATEWAY_PASSWORD"

Configuration

Power Dash can be configured via command-line flags, environment variables (POWER_DASH_*), or a power-dash.yaml file (searched in ./, ~/., and /etc/power-dash/).

Option	Flag	Env Variable	Default
Endpoint	--endpoint	POWER_DASH_ENDPOINT	https://192.168.91.1/
Password	--password	POWER_DASH_PASSWORD	(required)
Listen address	--listen	POWER_DASH_LISTEN	:8080
Connection mode	--connection-mode	POWER_DASH_CONNECTION_MODE	wifi
RSA key path	--key-path	POWER_DASH_KEY_PATH	tedapi_rsa_private.pem
Gateway DIN	--din	POWER_DASH_DIN	(auto-detected)
Collection interval	--collection-interval	POWER_DASH_COLLECTION_INTERVAL	30 (seconds)
Log level	--log-level	POWER_DASH_LOG_LEVEL	info
Storage path	--storage-path	POWER_DASH_STORAGE_PATH	/data
Storage retention	--storage-retention	POWER_DASH_STORAGE_RETENTION	0s (infinite)

🔌 Connection Modes

Power Dash supports two ways to connect to your Powerwall gateway.

WiFi Mode (Default)

Connect over your local network using the gateway's IP and installer password. This is the simplest setup and works for most users, but requires a device with 2 network connections:

• WiFi connected to the powerwall/gateway's internal wifi
• Wifi/LAN connected to your local network

# power-dash.yaml
endpoint: "https://192.168.91.1/"
password: "YOUR_INSTALLER_PASSWORD"
connection-mode: wifi

The installer password is printed on the QR sticker inside your gateway enclosure.

LAN Mode

LAN mode uses RSA-signed requests directly to the gateway's TEDAPI endpoint.

This requires a one-time setup using a Tesla developer account.

Prerequisites

• A Tesla Developer app with energy_device_data and energy_cmds scopes

Step 1: Download the binary

Download the appropriate binary for your OS from the Releases page and make it executable:

chmod +x power-dash

Step 2: OAuth Login

Run the interactive auth flow. This opens a browser for Tesla OAuth, starts a localtunnel for the callback, and registers your app with the Fleet API.

power-dash connect auth \
  --client-id YOUR_TESLA_CLIENT_ID \
  --client-secret YOUR_TESLA_CLIENT_SECRET

Tokens are saved to fleet_tokens.json.

Step 3: Register your RSA Key

This generates an RSA-4096 key pair (if one doesn't exist), registers it with your Powerwall via the Fleet API, and walks you through physical confirmation via a breaker toggle.

power-dash connect keys add

At the end of the command, you'll see a config snippet like:

┌─ Add to your config ──────────────────┐
│ connection-mode: lan                  │
│ key-path: tedapi_rsa_private.pem      │
│ din: 1234567-00-A--AA0000000000AA     │
└───────────────────────────────────────┘

Step 4: Update your config

Copy config/power-dash-lan.example.yaml to power-dash.yaml and fill in your values:

endpoint: https://192.168.91.1/
password: YOUR_INSTALLER_PASSWORD
connection-mode: lan
key-path: tedapi_rsa_private.pem
din: 1234567-00-A--AA0000000000AA # from 'keys add' output

Key Management

# List registered keys and their verification state
power-dash connect keys list

# Remove a key by its base64-encoded public key
power-dash connect keys remove <PUBLIC_KEY>

🧑‍💻 Development

git clone https://github.com/ygelfand/power-dash.git
cd power-dash

# Start backend + frontend in dev mode
make run-dev
# Backend:  http://localhost:8080
# Frontend: http://localhost:8000

# Build standalone binary with embedded UI
make all
./bin/power-dash run --help
