Pax App Bluetooth Server

Self-hosted version of the PAX web app (web-app.pax.com/device), a Web Bluetooth client for controlling PAX vaporizers. PAX is shutting their hosted version down in May 2026, so this is a local-only fallback assembled from a HAR capture of the live site.

Run

cd local-app && node server.js

Then open http://localhost:8443/device in Chrome (or another Chromium-based browser with Web Bluetooth support).

Web Bluetooth works over localhost without HTTPS. To access this from another device on your network you'll need to run it behind TLS — set USE_HTTPS=1, SSL_CERT, and SSL_KEY.

What's in here

• local-app/static/ — the React bundle and assets, extracted as-is from the HAR. The bundle is patched in one place: the API base URL is rewritten from https://consumer-service.cf-production.pax.com/api/v1 to /api/v1.
• local-app/server.js — small Node server: serves the static files and mocks the /api/v1 endpoints the app calls.
• local-app/overrides.css / overrides.js — UI cleanup: hides the top nav and end-of-life banner, auto-declines the usage-data consent modal so the app actually mounts. Also blocks outbound telemetry (Bugsnag, Google Tag Manager) at the fetch/XHR/<script src> layer.

Caveats

• Account/sync features are mocked with empty stubs — saved devices, firmware updates, account history, etc.
• Only tested with the PAX Era Pro. Other PAX devices are expected to work, but untested. If something needs fixing, open a PR.
• Frozen at the bundle version captured in April 2026.
