It's free. Pay $0 and take everything — it's open-source on GitHub. Two steps and it's live; a third if you want your AI to answer.
🔓 AGPL-3.0 · no account · no tracking · it's yoursOn a Pi Zero 2 W with Raspberry Pi OS Lite, paste this. The installer does the rest — display, services, anti-ban defaults — and prints your MCP token once.
$ git clone https://github.com/chamilonster/Piumy $ cd Piumy && sudo ./deploy/install.sh
When it's up, Piumy shows a QR (on the e-paper, or in the dashboard). On your phone: WhatsApp → Linked devices → Link a device, and scan it. Use a dedicated number, not your main one. That's it — Piumy is live.
Point your AI (Claude Code, OpenCode, any MCP client) at Piumy with the token the installer printed:
$ claude mcp add --transport http piumy \
http://piumy.local:8081/mcp \
--header "Authorization: Bearer <token>"
Prefer a config file? The .mcp.json snippet is in the README. There's also a ready-made Claude Code skill that teaches your agent the rules and a human pace.
No board, no WhatsApp — just watch the face render. The core writes status.json; the file adapter draws it.
$ cd core && go run . responding $ cd ../adapters/display/file $ pip install -r requirements.txt && python render.py
Piumy is free and open-source under AGPL-3.0 — install it above and pay nothing, no account, no catch. But donations are the cornerstone: without them, Piumy stops at this MVP.
And don't let the name fool you — WhatsApp is only the kickoff. The plan is a secure personal gateway: mic, speaker, screens, buttons, APIs, encrypted tunnels — connecting almost anything, to give busy people and anyone the everyday is harder on a real hand. If that's worth something to you, chip in what you can.
