Uni Wireless Sync CLI

Warning: This is an unofficial implementation; use at your own risk.

Overview

Uni Wireless Sync (UWS) CLI provides command-line utilities for managing Uni Fan Wireless controllers, L-Wireless receivers, and LCD panels. Each command re-opens the required USB or RF device so no background daemon is left running, and lower-level HID/USB errors are surfaced directly to simplify scripting.

Supported Hardware

• UNI FAN TL wireless LCD panels
• UNI FAN TL wireless fans (non-LCD)

Other Uni Fan series are currently not supported.

Features

• Discover TL LCD USB devices and 2.4 GHz wireless fan controllers.
• Query LCD firmware and handshake data.
• Send JPEG frames or apply control settings (mode, brightness, rotation) to the LCD.
• Keep the wireless TL LCD awake by emitting periodic handshakes.
• List wireless fan receivers with metadata (MAC, master MAC, channel, device type, fan speeds, PWM targets).
• List detected master controller MAC addresses to simplify binding workflows.
• Send one-shot PWM commands to TL wireless fans over the 2.4 GHz dongle.
• Bind or unbind wireless receivers against the active master controller.
• Toggle motherboard PWM sync mode for one receiver or every bound receiver.
• Broadcast static RGB payloads to wireless receivers (experimental).

Fan wiring modes

• USB + PWM header (controller mode): leave the receiver's PWM lead unplugged; control every fan via uws fan set-fan (any PWM value 0-255). The reported fan_pwm reflects your last command.
• USB-only (receiver mode, PWM lead connected to motherboard): the CLI writes a PWM of 6 (e.g. uws fan pwm-sync --mode receiver --all) so the receiver keeps syncing to the motherboard header. Sending another set-fan value at any time overrides the sync immediately; writing 6 (or re-running the sync helper) hands control back to the motherboard.

FAQ

• How do I mount the L-Wireless Controller (v1)? The thicker dongle supports two options: (1) plug into a USB Type-A port—this wiring is equivalent to pwm-sync receiver mode; (2) plug the header into a 9-pin USB port on the motherboard—this matches pwm-sync controller mode, but 2.4 GHz signal strength drops because the dongle lives inside the chassis.
• How do I mount the L-Wireless Controller (v2)? The slimmer dongle only supports option (1): plug into a USB Type-A port (pwm-sync receiver mode).
• What is the difference between L-Wireless Receiver (v1) and (v2)? Receiver v1 exposes both USB and a 2-pin PWM lead only on the LCD bundle (USB powers the LCD, the 2-pin lead powers fans); non-LCD receiver v1 units ship with just the 2-pin power lead. Receiver v2 adds a dedicated 4-pin PWM header; plug it into the motherboard when you want it to mirror the motherboard duty cycle via pwm-sync --mode receiver, or leave it disconnected and the controller will keep driving fan PWM directly.

Installation

pip install uwscli
# optional image helpers
pip install uwscli[images]

python -m venv .venv
source .venv/bin/activate
pip install -e .
# or include dev extras
pip install -e .[dev]

Usage Examples

# Enumerate connected devices
uws lcd list
uws fan list

# Display operations
uws lcd info --serial <usb-serial>
uws lcd send-jpg --serial <usb-serial> --file assets/sample_lcd.jpg
uws lcd keep-alive --serial <usb-serial> --interval 5

# Fan receiver operations
uws fan set-fan --mac aa:bb:cc:dd:ee:ff --pwm 120  # direct PWM control
uws fan pwm-sync --mode receiver --all           # receiver mode receivers (sets PWM=6)
uws fan bind --mac aa:bb:cc:dd:ee:ff
uws fan unbind --mac aa:bb:cc:dd:ee:ff
uws fan pwm-sync --all
uws fan pwm-sync --mac aa:bb:cc:dd:ee:ff --once

uws lcd list prints JSON rows that include a serial field—copy that value when invoking other LCD subcommands.

Command Reference

• uws lcd list – enumerate TL LCD devices and show their USB serial numbers.
• uws lcd info --serial <usb-serial> – read firmware and handshake data.
• uws lcd send-jpg --serial <usb-serial> --file <image.jpg> – stream a JPEG asset.
• uws lcd keep-alive --serial <usb-serial> [--interval seconds] – emit periodic handshakes to prevent the wireless panel from dimming.
• uws lcd control --serial <usb-serial> [--mode show-jpg|show-app-sync|lcd-test] [--jpg-index N] [--brightness 0-100] [--fps N] [--rotation 0|90|180|270] [--test-color R,G,B] – send an LCDControlSetting payload.
• uws fan list – fetch a snapshot of bound wireless receivers via the RF receiver.
• uws fan list-masters – enumerate master controllers and associated wireless receivers.
• uws fan set-fan --mac <aa:bb:..> --pwm <0-255> [--sequence-index N] – send a single shot PWM update to one receiver; --all broadcasts to every bound receiver.
• uws fan pwm-sync --mac|--all [--mode controller|receiver] [--interval seconds] [--once] [--sequence-index N] – synchronize receiver speeds. controller polls motherboard PWM and replays the value via RF (--interval / --once apply here); receiver sets PWM=6 so the receiver tracks the motherboard header directly (--sequence-index applies here).
• uws fan set-led --mac <aa:bb:..> --mode static|rainbow|frames|effect|random-effect – apply wireless LED effects (experimental).

uws fan set-led modes

• static: requires --color R,G,B or --color-list R,G,B;... to paint the LED strip once.

• rainbow: procedural rainbow; optional --frames N (default 24) and --interval-ms (default 50).

• frames: feed a JSON animation via --frames-file. Each frame is an array of [R, G, B] triples; see examples/tl_frames_sample.json for a minimal illustration (the CLI will pad or truncate per device LED count).

• effect: drives any of the 29 TL presets. Choose an effect with --effect <name> (e.g. twinkle, meteor_shower), adjust brightness 0‑255 via --effect-brightness, pick direction with --effect-direction 0|1, and select which segment to update using --effect-scope front|behind|both (default both).

• random-effect: picks a random preset each time; accepts the same brightness/direction/scope flags as effect.

  Available effect names (case-insensitive): rainbow, rainbow_morph, static_color, breathing, runway, meteor, color_cycle, staggered, tide, mixing, voice, door, render, ripple, reflect, tail_chasing, paint, ping_pong, stack, cover_cycle, wave, racing, lottery, intertwine, meteor_shower, collide, electric_current, kaleidoscope, twinkle.

  Example:

  uws fan set-led --mac aa:bb:cc:dd:ee:ff --mode effect --effect twinkle --effect-brightness 180 --effect-direction 0 --effect-scope both
  

  Random example:

  uws fan set-led --mac aa:bb:cc:dd:ee:ff --mode random-effect --effect-brightness 200 --effect-direction 1
  

• uws fan pwm-sync --all|--mac [--mode controller|receiver] [--interval seconds] [--once] [--sequence-index N] – default receiver mode writes PWM=6 so fans follow the motherboard; controller mode polls and replays PWM from the motherboard (supports --interval/--once for polling loops; --sequence-index applies to receiver broadcasts).

Dependencies

• hidapi (via hid) for TL LCD HID access.
• pyusb for the RF sender/receiver WinUSB endpoints.
• pycryptodomex for the DES-CBC transport used by the wireless LCD receiver.
• Pillow is optional for JPEG frame validation.

Each command expects the TL LCD USB display (vendor 0x04FC or 0x1CBE) and the wireless transmitter/receiver pair (vendor 0x0416) to be attached when the command executes.
