pywizlight

A Python connector for WiZ light bulbs.

Tested with the following smart lights:

• Original Phillips Wiz WiFi LEDs
• SLV Play RGB bulb
• WiZ Smart LED

Install

pip install pywizlight

Note: Requires Python version >=3.7.

On a Fedora-based system or on a CentOS/RHEL 8 machine which has EPEL enabled, as pywizlight is present in the Fedora Package Collection.

sudo dnf -y install python3-pywizlight

Kudos

Thank you @angadsingh for make such incredible improvements!!

Thanks to @fabaff for the CLI tool and some code rework!

Example

import asyncio

from pywizlight import wizlight, PilotBuilder, discovery

async def main():
    """Sample code to work with bulbs."""
    # Discover all bulbs in the network via broadcast datagram (UDP)
    # function takes the discovery object and returns a list with wizlight objects.
    bulbs = await discovery.find_wizlights()
    # Print the IP address of the bulb on index 0
    print(f"Bulb IP address: {bulbs[0].ip}")

    # Iterate over all returned bulbs
    for bulb in bulbs:
        print(bulb.__dict__)
        # Turn off all available bulbs
        # await bulb.turn_off()

    # Set up a standard light
    light = wizlight("192.168.0.170")
    # Set up the light with a custom port
    #light = wizlight("your bulb's IP address", port=12345)

    # The following calls need to be done inside an asyncio coroutine
    # to run them fron normal synchronous code, you can wrap them with
    # asyncio.run(..).

    # Turn on the light into "rhythm mode"
    await light.turn_on(PilotBuilder())
    # Set bulb brightness
    await light.turn_on(PilotBuilder(brightness = 255))

    # Set bulb brightness (with async timeout)
    timeout = 10
    await asyncio.wait_for(light.turn_on(PilotBuilder(brightness = 255)), timeout)

    # Set bulb to warm white
    await light.turn_on(PilotBuilder(warm_white = 255))

    # Set RGB values
    # red to 0 = 0%, green to 128 = 50%, blue to 255 = 100%
    await light.turn_on(PilotBuilder(rgb = (0, 128, 255)))

    # Get the current color temperature, RGB values
    state = await light.updateState()
    print(state.get_colortemp())
    red, green, blue = state.get_rgb()
    print(f"red {red}, green {green}, blue {blue}")

    # Start a scene
    await light.turn_on(PilotBuilder(scene = 4)) # party

    # Get the name of the current scene
    state = await light.updateState()
    print(state.get_scene())

    # Get the features of the bulb
    bulb_type = await bulb.get_bulbtype()
    print(bulb_type.features.brightness) # returns true if brightness is supported
    print(bulb_type.features.color) # returns true if color is supported
    print(bulb_type.features.color_tmp) # returns true if color temperatures are supported
    print(bulb_type.features.effect) # returns true if effects are supported
    print(bulb_type.kelvin_range.max) # returns max kelvin in in INT
    print(bulb_type.kelvin_range.min) # returns min kelvin in in INT
    print(bulb_type.name) # returns the module name of the bulb

    # Turns the light off
    await light.turn_off()

    # Do operations on multiple lights parallely
    #bulb1 = wizlight("<your bulb1 ip>")
    #bulb2 = wizlight("<your bulb2 ip>")
    #await asyncio.gather(bulb1.turn_on(PilotBuilder(brightness = 255)),
    #    bulb2.turn_on(PilotBuilder(warm_white = 255)), loop = loop)

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

CLI

wizlight is a command-line tool to perform basic interactions with bulbs.

$ wizlight
Usage: wizlight [OPTIONS] COMMAND [ARGS]...

  Simple command-line tool to interact with Wizlight bulbs.

Options:
  --version  Show the version and exit.
  --help     Show this message and exit.

Commands:
  discover  Disocver bulb in the local network.
  off       Turn the bulb off.
  on        Turn the bulb on.
  state     Get the current state from the given bulb.

Discovery

The discovery works with an UDP Broadcast request and collects all bulbs in the network.

Bulb paramters (UDP RAW)

• sceneId - calls one of thr predefined scenes (int from 0 to 32) List of names in code
• speed - sets the color changing speed in percent
• dimming - sets the dimmer of the bulb in percent
• temp - sets color temperature in kelvins
• r - red color range 0-255
• g - green color range 0-255
• b - blue color range 0-255
• c - cold white range 0-255
• w - warm white range 0-255
• id - the bulb id
• state - when it's on or off
• schdPsetId - rhythm id of the room

Async I/O

For async I/O this component uses https://github.com/jsbronder/asyncio-dgram, which internally uses asyncio DatagramTransport, which allows completely non-blocking UDP transport

Classes

wizlight(ip): Creates a instance of a WiZ Light Bulb. Constructed with the IP address of the bulb.

Instance variables

You need to first fetch the state by calling light.updateState(). After that all state can be fetched from light.state, which is a PilotParser object.

PilotParser.get_brightness()gets the value of the brightness 0-255

PilotParser.get_rgb() get the rgbW color state of the bulb

PilotParser.get_colortemp() get the color temperature ot the bulb

PilotParser.get_warm_white/get_cold_white() get the current warm/cold setting (not supported by original Phillips Wiz bulbs)

PilotParser.get_scene() gets the current scene name

PilotParser.get_state() returns true or false / true = on , false = off

Methods

getBulbConfig(self) returns the hardware configuration of the bulb

updateState(self) gets the current bulb state from the light using sendUDPMessage and sets it to self.state

lightSwitch(self) turns the light bulb on or off like a switch

getMAC(self) returns the MAC address of the bulb. Can be used as unique ID.

sendUDPMessage(self, message, timeout = 60, send_interval = 0.5, max_send_datagrams = 100): sends the udp message to the bulb. Since UDP can loose packets, and your light might be a long distance away from the router, we continuously keep sending the UDP command datagram until there is a response from the light. This has in tests worked way better than just sending once and just waiting for a timeout. You can set the async operation timeout using timeout, the time interval to sleep between continuous UDP sends using send_interval and the maximum number of continuous pings to send using max_send_datagrams. It is already hard coded to a lower value for setPilot (set light state) vs getPilot (fetch light state) so as to avoid flickering the light.

turn_off(self) turns the light off

turn_on(PilotBuilder) turns the light on. This take a PilotBuilder object, which can be used to set all the parameters programmatically - rgb, color temperature, brightness, etc. To set the light to rhythm mode, create an empty PilotBuilder.

Bulb methods (UDP native):

• getSystemConfig - gets the current system configuration - no parameters need
• syncPilot - sent by the bulb as heart-beats
• getPilot - gets the current bulb state - no parameters need to be included
• setPilot - used to tell the bulb to change color/temp/state
• Pulse - uncertain of purpose
• Registration - used to "register" with the bulb: This notifies the built that it you want it to send you heartbeat sync packets.

Sync functions:

• syncUserConfig
• syncPilot - {"method":"syncPilot","env":"pro","params":{"mac":"ABCABCABC","rssi":-71,"src":"udp","state":true,"sceneId":0,"temp":6500,"dimming":62}}

• syncBroadcastPilot
• syncSystemConfig
• syncConfig
• syncAlarm

Set functions:

• pulse - {"method":"pulse", {"params":{"delta":-15,"duration":300}}

• setUserConfig
• setSystemConfig
• setDevInfo
• setSchd
• setSchdPset
• setWifiConfig
• reset
• setFavs
• setState
• setPilot

Get functions

• getUserConfig
• getSystemConfig
• getWifiConfig

• Invalid Request
• Method not found
• Invalid params
• Internal error

Example UDP requests

Send message to the bulb: {"method":"setPilot","params":{"r":255,"g":255,"b":255,"dimming":50}} Response: {"method":"setPilot","env":"pro","result":{"success":true}}

Get state of the bulb: {"method":"getPilot","params":{}} Responses:

custom color mode:
