LOCAL DATA. OPEN POSSIBILITIES.

Stop reverse engineering.
Start building.

Connect to Nova on your local network and receive shot data as JSON. Use the documented TCP or WebSocket API to build the golf experience you want.

  1. Discover Nova with mDNS.
  2. Receive shots as they happen.
  3. Use the data in your own applications.

03INTEGRATION

Home Assistant Integration

Bring Nova shot and device data into your smart home. Build dashboards, log sessions, or trigger automations around your hitting bay.

Automate your setup
04DRAFT 2 / RFC

Common Golf Protocol

A proposed communication framework for launch monitors, swing radars, control boxes, and simulator software. Run the examples and contribute.

A protocol in development. The specification is provisional.

HOME ASSISTANT / BUILT WITH NOVA

Make Nova part of your smart home.

Your hitting bay can do more than record a shot. Bring Nova shot and device data into Home Assistant as sensors, then build automations around your setup.

  • Set the scene with lights and music in your hitting bay.
  • Trigger a celebration when a shot hits your ball speed target.
  • Log shot data to your own dashboard or database.
