pyskyrc

Pure-Python control and telemetry for SkyRC Q200neo / T1000 chargers via USB HID and Bluetooth LE.

Reverse-engineered from the official Charge Master 1.55.E207 protocol. No Charge Master or SkyRC app required.

Features

• Two transports — USB HID and BLE with the same Python API.
• 4 ports — A / B / C / D, each with independent telemetry.
• Live cells — 6 × cell voltage, temperature, total V, delta.
• Full control — START / STOP charge with full parameter set.
• All chemistries — LiPo, LiIo, LiFe, LiHV, NiMH, NiCd, Pb.
• Auto-discovery (BLE) — finds the charger by service UUID.
• MAC cache — fast reconnect after first successful session.
• Interactive shell — one connection, many commands.
• Pure Python — only bleak needed for BLE; USB has no deps.

Install

pip install pyskyrc
pip install pyskyrc[ble]
pip install pyskyrc[ble,dev]

CLI

USB

pyskyrc info
pyskyrc status
pyskyrc monitor
pyskyrc start B --chem LiPo --cells 6 --current 2.0
pyskyrc stop B

BLE

pyskyrc --transport ble scan
pyskyrc --transport ble status
pyskyrc --transport ble start B --chem LiPo --cells 6 --current 2.0
pyskyrc --transport ble stop B

Interactive shell

pyskyrc --transport ble shell

Then inside the shell:

pyskyrc> status
pyskyrc> start B --chem LiPo --cells 6 --current 2.0
pyskyrc> monitor
pyskyrc> stop B
pyskyrc> exit

Python API

from pyskyrc import (
    SkyRCCharger, ChargeParameters, Port, Chemistry, LiMode,
)

with SkyRCCharger(transport="usb") as charger:
    for port, info in charger.read_telemetry().items():
        if info.has_battery:
            print(port.name, info.total_v, info.temperature_c)

    params = ChargeParameters(
        chemistry=Chemistry.LiPo,
        cells=6,
        mode=LiMode.BALANCE_CHARGE,
        charge_current_a=2.0,
    )
    charger.start_charge(Port.B, params)
    charger.stop_charge(Port.B)

For BLE, replace transport="usb" with transport="ble".

Protocol

Full protocol documentation is in docs/protocol.md.

Safety

This library controls a real charger with real current. You are responsible for choosing a chemistry and cell count that match your battery, choosing safe currents, and not leaving charging unattended.
