openlamp-lamp 0.1.0

One-shot CLI to control Tuya smart lamps locally (colour, brightness, on/off) — the OpenLamp/LumiDeck command-line frontend.

OpenLamp Engine

The core layer of the OpenLamp family: instant, 100% local control of smart LED lamps (WLED recommended, Tuya also supported), exposed through a stable command contract — OpenLamp State (OLS), a WLED-compatible JSON state patch (see OLS.md).

Part of the OpenLamp family:

Layer	Repo	Role
Engine (this repo)	openlamp/engine	drivers + dispatcher + local API + daemon + CLI (Python reference)
Engine, JS port	engine-js	same contract on Node/tuyapi — for JS-first environments
Stream Deck frontend	lumideck	keys, dials, live status on an Elgato Stream Deck
MIDI frontend	openlamp-midi	stage control from physical MIDI controllers

Install the lamp CLI (PyPI)

The one-shot command-line frontend is published as openlamp-lamp:

pip install openlamp-lamp

lamp rouge            # set colour (keeps brightness)
lamp bri:60           # brightness 1-100
lamp veilleuse        # a brightness preset (lueur/veilleuse/tamise/moyen/fort/max)
lamp on | off

It finds your lamp config (with local keys) from $LUMIDECK_LAMPS, else ~/.config/openlamp/tuya-lamps.json (template at the bottom of this README). If the LumiDeck plugin/daemon is running, the CLI routes through its local API (127.0.0.1:8377) for instant response; otherwise it drives the lamps directly.

Only the CLI (lamp.py) ships on PyPI. The engine + headless daemon stay in this repo (they couple to a local file layout — a clean engine package is a follow-up).

What's inside

• engine.py — the engine: one thread per lamp with a persistent connection (sub-200 ms commands), the OLS dispatcher, groups, snapshots, animations (cycle/flash/tempo), connect-time sync, a rainbow welcome sweep, and the local API on 127.0.0.1:8377 (/cmd, /status, /syntax, plus the optional WLED-compat /json/state). Frontend-agnostic: its only upward link is an on_change hook.
• daemon.py — headless host: runs the engine without any frontend app.
• run-headless.sh — one command to switch to CLI/MIDI-only mode.
• lamp-doctor.sh (macOS) — one-command diagnosis of "lamps unreachable", testing the three causes in order: Mac on the wrong Wi-Fi / router down / lamp powered off or radio-napping. Never trust the router's web panel (it renders from service-worker cache even with the router dead) — this script is the ground truth.
• lamp.py — the CLI (also Bome-callable): lamp.py vert, lamp.py bri:40… Routes through the local API when a host runs, drives lamps directly otherwise.
• com.benlab.lumideck-daemon.plist — launchd autostart for the daemon.
• OLS.md — the OpenLamp State contract. TUYA-KEYS.md — how to get your lamps' local keys (official Tuya cloud API, one-time).

One host at a time — the rule

Every host binds port 8377 (and a Tuya lamp additionally accepts only one local connection). So run either the Stream Deck plugin (it embeds this engine in-process) or daemon.py — never both. Deck sessions → plugin; CLI/MIDI-only sessions → daemon.

Why 8-bit values (0–255)

OLS uses 8-bit for brightness and per-channel color, for three reasons:

1. WLED compatibility — WLED's JSON API is 8-bit; OLS is a compatible patch.
2. It matches the hardware — RGB LEDs are driven 8 bits per channel (16.7 M colors); Tuya's internal 0–1000 scale adds no perceptible precision.
3. It matches perception — ~1 % brightness steps are at the threshold of what the eye distinguishes; 256 levels cover that. MIDI frontends (7-bit, 0–127) scale up ×2 — plenty for stage cues.

Config

tuya-lamps.json sits next to lamp.py (never committed — it contains your local keys). Template:

{
  "lamps": [
    {"name": "L1", "mac": "aa:bb:cc:dd:ee:ff", "device_id": "…", "local_key": "…",
     "ips": {"192.168.1": "192.168.1.50"}}
  ],
  "groups": {"front": ["L1"]},
  "sync": {"enabled": true, "state": {"on": true, "col": [0, 100, 200], "bri": 153}}
}

Test hardware (budget setup)

The engine and LumiDeck are developed and tested on this cheap, off-the-shelf rig — reproduce it for well under €40 for a two-lamp stereo stage:

• Bulbs — Athom WLED 7 W Color Bulb (E27, ESP32-C3, RGB + tunable white, WLED-preflashed, ~€13 each). WLED ships already flashed — put the bulb on Wi-Fi and it's auto-discovered. This is the reference bulb every timing figure is measured on (~45 ms/command, the latency-comp floor beatsync uses).
• Socket / holder — TobeBright E27 corded lamp holder with inline switch (up to 100 W, a few € on Amazon). Turns a bare bulb into a standalone plug-in stage lamp — no fixture required, just screw the bulb in and plug it to mains.

Publishing to PyPI (maintainer)

openlamp-lamp publishes via Trusted Publishing (OIDC) — no token in the repo. .github/workflows/publish.yml builds + publishes on each GitHub Release. One-time:

1. PyPI → Add a pending publisher (https://pypi.org → Publishing): project openlamp-lamp, owner openlamp, repo engine, workflow publish.yml, environment pypi.
2. GitHub → Settings → Environments → New → pypi.
3. Bump version in pyproject.toml, commit, cut a GitHub Release (tag v0.1.0) → the workflow builds and publishes. Then pip install openlamp-lamp works everywhere.
