- Remove frontend dependencies that aren't in Nix package
- Use minimal config with just HTTP, API, and MQTT
- Prepare for either Docker alternative or core-only testing
- Remove mosquitto from flake (use existing broker)
- Point dev config to mqtt.home instead of localhost
- Cleaner setup using your existing MQTT infrastructure
- Add home-assistant and mosquitto to dev shell
- Create minimal dev-config/ for HA development instance
- Symlink custom integration for easy testing
- Add HA dev files to .gitignore
- No HA codebase committed, just references via Nix
Usage:
nix develop
hass --config ./dev-config
Features:
- Isolated from production HA instance
- MQTT broker for testing
- Debug logging enabled
- In-memory database for fast iteration
- Create basic integration structure with manifest.json
- Add config flow for easy setup via UI
- Implement MQTT-based host discovery and sensor creation
- Auto-discover Systant hosts via systant/+/stats topic
- Create device entities with last_seen sensor for each host
- Add Python tooling to flake.nix for HA development
Integration features:
- Automatic host discovery via MQTT
- Device representation for each monitored host
- Extensible sensor architecture
- Proper Home Assistant integration patterns
- Remove dummy COOKIE file creation (doesn't work in Nix store)
- Set RELEASE_COOKIE env var in wrapper script instead
- This follows NixOS best practices for Elixir releases
- Remove server/_build/ and server/deps/ from git tracking
- Update .gitignore to properly ignore server build directories
- These directories caused symlink conflicts in Nix build

- Move Elixir code to server/ subdirectory for monorepo structure
- Update flake.nix to provide packages and apps outputs for nix run support
- Update nix/package.nix to accept src parameter instead of fetchgit
- Add NixOS module export for easy consumption
Now supports: nix run, nix build, and nix develop from git repo

- Topics now default to systant/{hostname}/stats and systant/{hostname}/commands
- Runtime config automatically includes system hostname in topics
- NixOS module defaults use config.networking.hostName
- Supports multiple hosts without topic conflicts
- Environment variables can still override if needed
Example: systant/orion/stats, systant/server2/stats, etc.

Set RELEASE_COOKIE environment variable directly in systemd service
to prevent startup script from trying to read non-existent COOKIE file.
The environment variable takes precedence over file reading.

- Remove explicit cookie configuration from release
- Set RELEASE_DISTRIBUTION=none and RELEASE_NODE=nonode@nohost
- Simplify Nix derivation by removing postInstall hooks
- Single standalone daemon doesn't need Erlang node clustering
Fixes persistent COOKIE file issues in Nix builds.
