Frequently Asked Questions

Do I need a smartphone to use HypeRate Web Bluetooth?

No. HypeRate Web Bluetooth works entirely in your desktop Chrome browser. No smartphone, no companion app, and no USB cable is needed. Just open Chrome, click Connect Device, and you are live in under 20 seconds.

Which browsers support Web Bluetooth?

Google Chrome is required as it fully supports the Web Bluetooth API. Chromium-based browsers such as Microsoft Edge and Brave may also work. Firefox and Safari do not currently support Web Bluetooth.

How do I add my heart rate overlay to OBS?

After connecting your heart rate monitor, click "Copy URL for OBS." In OBS Studio, add a new Browser Source and paste the copied URL. Set width and height to match your desired overlay dimensions. Your live BPM will appear in your stream scene immediately.

What is the HypeRate ID?

Your HypeRate ID is a unique 7-character alphanumeric identifier that links your browser session to your HypeRate streaming widget. It is stored locally in your browser's localStorage and persists between sessions. You can generate a new ID at any time — this will change your widget URL.

Is HypeRate Web Bluetooth free?

Yes. HypeRate Web Bluetooth is completely free to use. No account registration or subscription is required for the core streaming functionality.

Does it work with Twitch, YouTube, and other platforms?

Yes. The OBS Browser Source widget works with any streaming platform, including Twitch, YouTube, Facebook Gaming, Kick, and more. Any service that accepts OBS as a streaming source supports the HypeRate heart rate overlay.

Why does my battery level show "--"?

Not all BLE heart rate monitors expose the battery_service GATT profile. If your device doesn't support it, the battery reading stays hidden — but BPM data still streams normally. Try reconnecting or checking your device's documentation.
