Tesla Even G2

See also: G2 development notes – hardware specs, UI system, input handling and practical patterns for Even Realities G2.

Tesla vehicle controls for Even Realities G2 smart glasses.

35+ commands across climate, charging, security, windows and more – all from your glasses. View battery, range, temperatures, charging and sentry status at a glance with a live map showing your car's location.

Fully client-side. The app runs as static HTML + JS in the Even Hub webview and talks directly to the Tessie API.

Your Tessie token is stored in localStorage on your phone and sent directly to api.tessie.com. It never touches any third-party server.

  index.ts         App module registration
  main.ts          Bridge connection + settings UI bootstrap
  app.ts           Thin orchestrator: initApp, refreshState
  state.ts         VehicleState type, app state singleton, bridge holder
  api.ts           Direct Tessie API client: getState, sendCommand, getMap
  actions.ts       Action type system, all 6 categories with 35+ commands
  navigation.ts    Stack-based menu navigation controller
  events.ts        Event normalisation + screen-specific dispatch

  layout.ts        Display dimension constants
  ui.tsx           React settings panel (token input, connection status)

app.ts is the entry point that wires everything together. On startup it fetches vehicle state via api.ts, stores it in the state.ts singleton, and tells renderer.ts to paint the dashboard. User interactions flow through events.ts, which normalises raw SDK events and dispatches them based on the current screen. Menu navigation uses a stack in navigation.ts – pushing levels for categories, action lists and preset sub-menus, popping on back.

Commands are defined declaratively in actions.ts using four action types:

• Toggle – context-aware label and command based on vehicle state (e.g. Lock/Unlock)
• Command – simple one-shot command, optionally with query parameters
• Sub-menu – drills into a list of child actions (e.g. temperature presets)
• Refresh – triggers a state refresh

Actions are grouped into 6 categories: Quick actions (shown on dashboard), Climate, Charging, Security, Windows and Other. The resolveLabel and resolveCommand helpers turn any action into a concrete label and command based on current vehicle state.

The dashboard shows quick actions plus a "More >" entry. Selecting it pushes a category list onto the navigation stack. Selecting a category pushes its action list. Parameterized commands (temperature, charge limit, seat heating, etc.) push a preset sub-menu. Max depth is 3 levels.

Dashboard (quick actions + "More >")
  -> Categories (Climate, Charging, Security, Windows, Other)
     -> Action list
        -> Preset sub-menu (for parameterized commands)

Every non-dashboard screen has "< Back" at index 0. Double-tap always goes back one level.

Requires even-dev (Unified Even Hub Simulator v0.0.2).

cp -r "$(pwd)/g2" /path/to/even-dev/apps/tesla
cd /path/to/even-dev

The dashboard shows battery level, range, lock state and charging status in the header, a scrollable quick-actions list on the left, a live map on the right, and temperature/climate/sentry info in the footer. Menu screens use the full display width.

Quick actions (dashboard) – Lock/Unlock, Climate on/off, Open frunk, Open trunk, Flash lights, Honk, Refresh

Climate – Climate on/off, Defrost on/off, Wheel heater on/off, Set temperature (18/20/22/24/26 C), Seat heating (per-seat, levels 0–3), Seat cooling (per-seat, levels 0–3)

Charging – Charge port open/close, Start/Stop charging, Charge limit (50–100%), Charging amps (8/16/24/32/48 A)

Security – Sentry on/off, Valet on/off, Guest on/off, Keyless driving

Windows – Vent/Close windows, Vent/Close sunroof

Other – HomeLink, Boombox, Bio defense on/off, Wake
