neewerd 0.1.0

Thin BLE control daemon for Neewer TL90C/Infinity lights — pluggable I/O modules over the neewer library

neewerd

Thin, library-backed control daemon for Neewer TL90C / TL120C ("NEEWER Infinity") RGB tube lights.

neewerd is built on the neewer library and is based on the research documented in the neewer-hardware reference.

This package is the daemon shell only. All the byte-wise protocol knowledge, the Fleet BLE client, animation effects, the device book and the BlueZ self-heal live in the neewer library — neewerd depends on it (pinned neewer>=0.1.0,<0.2.0) and just wires pluggable I/O front-ends (socket / MQTT / OSC / HTTP+web UI / Art-Net / sACN) and an MCP server onto the library's Fleet.

python -m neewerd [config.toml]

New protocol verbs (rgbcw / xy / gel by-MAC colour, …) arrive for free the moment the library gains them: the daemon adds no per-verb code, only HTTP field-maps and MCP tool wrappers. On startup the config is validated — unknown top-level / [core] / [modules.*] keys are warned (a typo won't silently drop a setting).

Console scripts

• neewerd — the daemon itself.
• neewerctl — a thin client of the daemon's command socket.
• neewer-mcp — a stdio MCP server; a client of a running daemon's HTTP API (installed by pip install 'neewerd[mcp]').

Layout

• neewerd/__main__.py — entrypoint: load + validate config → start neewer.Fleet → start modules.
• neewerd/modules/ — I/O front-ends (socket, mqtt, osc, http, artnet, sacn) + the bundled web UIs. The artnet module drives tubes from DMX-over-IP with four personalities (hsi / cct / rgb / rgbw), so RGB/RGBW sources such as LedFx work directly; it paces BLE writes with a per-connection governor (auto-tuning, zero-config) so a fast source can't back up the Bluetooth transmit queue, and reports per-tube pacing telemetry (rate / bandwidth / latency / deferred).
• neewerd/client.py — DaemonClient: the shared async client of the daemon's /api/v1 HTTP layer (no bleak, no neewer BLE code). Consumed by neewer-mcp.
• neewerd/mcp_server.py — the MCP tools, built on DaemonClient.
• neewerd/socketpath.py — shared command-socket path resolver.

HTTP API

The http module serves a REST layer at /api/v1, a legacy line transport, a Server-Sent-Events stream that pushes on change (/api/v1/events), and the bundled web UIs (/, /console). The /console page shows full per-light detail (model / firmware / battery / temperature / RSSI / network id / last command) plus a write-pacing (governor) block and a system panel with a backpressure indicator; the state API and SSE stream carry the same per-tube pacing stats under a gov key. Full reference: docs/HTTP-API.md. Bind loopback — there is no auth/TLS.

Runtime signals

Tune a running daemon without a restart (a restart drops every BLE link):

• SIGUSR1 — toggle DEBUG logging on/off (watch the notify/GATT stream live).
• SIGUSR2 — reset the log level to the configured one.
• SIGHUP — re-read the config and hot-apply the safe subset: [presets] and [core.positions]. Roster keys and module knobs are read at startup only; the reload logs exactly what it ignored.

kill -USR1 $(pgrep -f 'python -m neewerd')

Install (local dev)

uv venv .venv
.venv/bin/pip install -e '.[all]'

(Or, with a sibling checkout of neewer-python to develop both at once: .venv/bin/pip install -e ../neewer-python -e '.[all]'.)
