Usage

The example below scans for Bluetooth LE devices and tries to control any which are supported.

For more detailed instructions, see the user guide.

import asyncio
from bleak import BleakScanner, BleakClient
from cheshire.compiler.state import LightState
from cheshire.generic.command import *
from cheshire.hal.devices import Connection, connect_to_ble_device

async def main():
    # Discover Bluetooth LE devices
    discover = await BleakScanner.discover()
    connections: list[Connection] = []

    # Connect to supported devices
    for bleak_device in discover:
        if bleak_device.name == None:
            continue

        # Connect to this device if it's one we support
        if connection := await connect_to_ble_device(bleak_device):
            print(f"Connected to {bleak_device.name}")

            connections.append(connection)

    async def send_all(state: LightState):
        # Push light state to connected devices
        for c in connections:
            await c.apply(state)
            

    # Update desired light state
    state = LightState()
    state.update(SwitchCommand(on=True))
    state.update(BrightnessCommand(0x30))
    state.update(RGBCommand(0x0e, 0x0, 0xaa))
    # state.update(EffectCommand(Effect.JUMP_7))

    await send_all(state)
