The plugin supports model switching, session management, and message streaming in memory, using signal-cli on the user's own machine.", "body_md": "Hi,\n\nI made this plugin to connects Pi coding agent and Signal as a hobby weekend project. You send a Note-to-Self message from your phone/desktop, pi picks it up, processes it, and it texts you back the answer.\n\nInstall it, run the setup wizard (or via /signal-setup), link your Signal number, and that's it. Some of the things it does:\n\n- reply to signal messages with reaction to so you know when it's processing/done. - ability to send a response to someone else in your contacts. Just say \"send this to Mike\" and it looks up the number and texts them, then confirms back to you. - you can switch models, start a new sessions, pause/resume without turning off the service. - only Note-to-Self messages are processed, everything from other people is ignored. - messages are streamed in-memory, nothing is written to a log file on disk (you can switch it on/off if you want to write to journalctl). - it uses signal-cli on your own machine with your own linked device.\n\nIt's a hobby project, so if you run into issues let me know and I'm happy to fix them.\n\nLink: [https://github.com/aalzubidy/pi-signal](https://github.com/aalzubidy/pi-signal) (available on NPM as well @aalzubidy/pi-signal)\n\nComments URL: [https://news.ycombinator.com/item?id=48828549](https://news.ycombinator.com/item?id=48828549)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-plugin-to-connect-pi-to-signal", "canonical_source": "https://github.com/aalzubidy/pi-signal", "published_at": "2026-07-08 07:01:28+00:00", "updated_at": "2026-07-08 07:30:13.654001+00:00", "lang": "en", "topics": ["ai-agents", "developer-tools"], "entities": ["Signal", "Pi", "GitHub", "NPM"], "alternates": {"html": "https://wpnews.pro/news/show-hn-plugin-to-connect-pi-to-signal", "markdown": "https://wpnews.pro/news/show-hn-plugin-to-connect-pi-to-signal.md", "text": "https://wpnews.pro/news/show-hn-plugin-to-connect-pi-to-signal.txt", "jsonld": "https://wpnews.pro/news/show-hn-plugin-to-connect-pi-to-signal.jsonld"}}
