Usage

Discover nearby devices

import asyncio
import pyzerproc


async def main():
    lights = await pyzerproc.discover(timeout=30)

    for light in lights:
        print("Address: {} Name: {}".format(light.address, light.name))

asyncio.get_event_loop().run_until_complete(main())

Turn a light on and off

import asyncio
import pyzerproc


async def main():
    address = "AA:BB:CC:00:11:22"

    light = pyzerproc.Light(address)

    try:
        await light.connect()
        await light.turn_on()

        await asyncio.sleep(5)

        await light.turn_off()
    finally:
        await light.disconnect()

asyncio.get_event_loop().run_until_complete(main())

Change the light color

import asyncio
import pyzerproc


async def main():
    address = "AA:BB:CC:00:11:22"

    light = pyzerproc.Light(address)

    try:
        await light.connect()

        while True:
            await light.set_color(255, 0, 0) # Red
            await asyncio.sleep(1)
            await light.set_color(0, 255, 0) # Green
            await asyncio.sleep(1)
    finally:
        await light.disconnect()

asyncio.get_event_loop().run_until_complete(main())

Get the light state

import asyncio
import pyzerproc


async def main():
    address = "AA:BB:CC:00:11:22"

    light = pyzerproc.Light(address)

    try:
        await light.connect()

        state = await light.get_state()

        if state.is_on:
            print(state.color)
        else:
            print("Off")
    finally:
        await light.disconnect()
