Show HN: Use your phone as a Windows mouse and keyboard, without a phone app

LocalTV Remote is an open-source Windows daemon that turns any phone into a wireless mouse, keyboard and system-volume remote via a browser-based PWA - no phone app required. A Node-based server runs on the PC and serves a controller UI over the LAN using HTTP+WebSocket; pairing is done with a QR and a six-digit PIN so phones store a token for future reconnects. Input is injected system-wide using Win32 SendInput (works in games and full-screen apps) and volume control talks directly to Windows Core Audio through a persistent PowerShell STA process. It supports multiple simultaneous phone controllers, is LAN-only with no cloud relay, and is designed to be lightweight (~27 MB installer, ~25-40 MB RAM idle) with no bundled Chromium.

Installation is available via winget or an installer, and developers can build from source with Node.js 22+. Security measures include origin checks, rate limiting (500 messages/sec per client), pairing routes restricted to loopback, and a single-instance lock; the server defaults to port 6776 with auto-port fallback. Project layout separates server, input, audio and PWA controller, and the input backend is abstracted for potential macOS/Linux ports. The project positions itself as a free, privacy-first alternative to freemium remotes that require companion phone apps or cloud accounts.
