noisebell/remote

Remote Services

Cargo workspace with the server-side pieces of Noisebell. Runs on any Linux box.

Service	Port	What it does
cache-service/	3000	Polls the Pi, stores history in SQLite, fans out webhooks
discord-bot/	3001	Posts door status to a Discord channel
rss-service/	3002	Serves an Atom feed of door events
noisebell-common/	—	Shared types and helpers

See each service's README for configuration and API docs.

Building

cargo build --release

Or with Nix:

nix build .#noisebell-cache
nix build .#noisebell-discord
nix build .#noisebell-rss

NixOS deployment

The flake exports NixOS modules. Each service runs as a hardened systemd unit behind Caddy.
