+# Telemetry Dashboard
+
+This Dash + Plotly application renders real-time telemetry from the tank fleet. It subscribes to the Redis `tank_status` stream (via the control broker) and visualizes:
+
+- Environment readings (temperature/humidity)
+- GPS trail and speed
+- Basic connection metadata (satellites, HDOP, timestamps)
+
+## Configuration
+
+Environment variables:
+
+| Variable | Default | Description |
+| --- | --- | --- |
+| `REDIS_URL` | `redis://localhost:6379/0` | Connection string for the telemetry Redis instance |
+| `REDIS_STATUS_STREAM` | `tank_status` | Redis stream containing incoming telemetry payloads |
+| `HISTORY_LIMIT` | `500` | Maximum number of samples kept in memory per process |
+| `REFRESH_INTERVAL_MS` | `3000` | Polling interval for the Dash client |
+
+## Development
+
+```bash
+cd telemetry_dashboard
+python -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+python app.py
+```
+
+Visit http://127.0.0.1:8050/ to view the dashboard.
+
+## Deployment
+
+Deploy like the other Elastic Beanstalk services:
+
+```bash
+zip -r telemetry-dashboard.zip .
+aws elasticbeanstalk create-application-version ... # etc.
+```
+
+The provided `Dockerfile` and `Procfile` mirror the other services in this repository for compatibility with the existing pipeline.
