# VoltDeck

> VoltDeck turns an iPad into a live dashboard for DIY electric vehicles: battery, power and speed, offline maps, backup camera, music and light control.

## What it is

VoltDeck is an iPad app that works as a live cockpit for DIY electric vehicles: trikes, golf carts, karts, conversions and art cars. It reads telemetry from the VoltDeck Bluetooth gateway (ESP32). It is coming soon to the App Store.

## Features

- Live telemetry: battery %, pack voltage, current, power, range, motor RPM, temperatures and the 12 V system. Up to 100 channels.
- Maps: a live map behind your gauges, a navigation view with a slim telemetry strip, and offline event maps.
- Backup camera: a Wi-Fi backup camera that opens automatically in reverse, with picture-in-picture.
- Lights and LEDs: switch headlight and auxiliary lights through your paired gateway, and control WLED LED lighting. Brake lights and turn signals stay hardwired.
- Music: see what's playing and play, pause or skip right from the dashboard.
- Your layout: build your own dashboards and vehicle profiles, log telemetry and export it as CSV or JSON.

## Pricing

- VoltDeck is free to download.
- VoltDeck Pro: 14.99 USD per month or 79.99 USD per year.
- Both plans start with a 7-day free trial.
- Billed through your Apple ID; cancel any time in Settings.

## Requirements

- iPad with iPadOS 15.6 or later (including iPad Air 2).
- The VoltDeck ESP32 Bluetooth gateway for live vehicle data.
- No hardware yet? A built-in simulator shows every screen with realistic data.

## Suggested sensors

- Required: classic ESP32 DevKit (ESP32-WROOM-32) running the VoltDeck gateway, isolated 12 V to 5 V DC-DC.
- Works today: pack voltage divider, 10k NTC thermistors, PC817 optocouplers for 12 V switch signals, relay module for headlight/aux lights, Wi-Fi MJPEG backup camera, WLED LED controller, built-in iPad GPS.
- Coming soon: Victron VE.Direct, smart BMS (JK, JBD, Daly, ANT, Orion, REC, Batrium), motor controllers (VESC, Kelly, FarDriver, Votol, Sevcon, Curtis and more), NMEA GPS, CAN, Modbus.

## What VoltDeck tracks

- Traction battery: SOC, SOH, voltage, current, power, energy remaining, Ah used, runtime, temperature, cell min/max/delta.
- 12 V aux battery, motor (RPM, temp, current, power, hours), controller (temp, currents, throttle, mode, regen, faults).
- Speed, trip, odometer, range, pitch/roll/yaw; gear, reverse, brake, ignition, lights; GPS; charging; solar; enclosure temps; custom sensors.

## Privacy

No account, no tracking, no ads, and no data collection. Telemetry, location and logs stay on your iPad unless you export them yourself.

## For AI agents

- MCP server: Streamable HTTP at https://getvoltdeck.com/volt/mcp (POST JSON-RPC 2.0, stateless). Tools: get_app_info, get_pricing, get_support_faq (optional "query" filter).
- REST API: GET https://getvoltdeck.com/api/app-info and GET https://getvoltdeck.com/health, described in the OpenAPI file.
- Authentication: none. Every endpoint is public and read-only, and there is no user data.
- Rate limit: 60 requests per minute per IP on /api/* and /mcp. Responses include RateLimit-Limit, RateLimit-Remaining and RateLimit-Reset headers. Over the limit you get HTTP 429 with a Retry-After header and a JSON body {"error": "rate_limited", "message": "..."}. Wait Retry-After seconds, then retry.
- Safe retries: every operation is a read, so retrying is always safe. You may send an Idempotency-Key header (1-255 visible ASCII characters); it is echoed back in the response.
- Errors are JSON: {"error": "<code>", "message": "<text>"}. MCP errors use standard JSON-RPC error objects.
