pywizlight

A python connector for WiZ light bulbs.

Tested with the following smart lights:

• Original Phillips Wiz WiFi LEDs
• SLV Play RGB bulb

Install

pip install pywizlight

Kudos

Thank you @angadsingh for make such incredible improvements!!

Example

    from pywizlight.bulb import wizlight, PilotBuilder
    # create/get the current thread's asyncio loop
    loop = asyncio.get_event_loop()
    # setup a standard light
    light = wizlight("<your bulb ip")
    # setup the light with a custom port
    light = wizlight("<your bulb ip",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(..)
    #see test.py for examples

     # 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_secs=10
    await asyncio.wait_for(light.turn_on(PilotBuilder(brightness = 255)), wait_secs)

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

    # set rbb 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())
    r, g, b = state.get_rgb()
    print("red %i green %i blue %i" % (r, g, b))

    # start a scene 
    await light.turn_on(PilotBuilder(scene = 14)) # party

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

    # 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)

Bulb paramters (UDP RAW):

• sceneId - calls one of thr predefined scenes (int from 0 to 32) Wiki
• 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. Constructor with ip 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

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.

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:

{'method': 'getPilot', 'env': 'pro', 'result': {'mac': 'a8bb50a4f94d', 'rssi': -60, 'src': '', 'state': True, 'sceneId': 0, 'temp': 5075, 'dimming': 47}}

scene mode:

{'method': 'getPilot', 'env': 'pro', 'result': {'mac': 'a8bb50a4f94d', 'rssi': -65, 'src': '', 'state': True, 'sceneId': 12, 'speed': 100, 'temp': 4200, 'dimming': 47}}

rhythm mode:

{'method': 'getPilot', 'env': 'pro', 'result': {'mac': 'a8bb50a4f94d', 'rssi': -63, 'src': '', 'state': True, 'sceneId': 14, 'speed': 100, 'dimming': 100, 'schdPsetId': 9}}
