nanocontroller 1.0.3

NanoLeaf controller

NanoController Python Package

Overview

The nanocontroller package allows you to interface with Nanoleaf devices, providing functionality for controlling individual lights programmatically, setting timers, and displaying weather information.

---

Installation

pip install nanocontroller

---

Authorization

To use the Nanoleaf OpenAPI, physical access to the device is required:

Hold the on-off button for 5-7 seconds until the LED starts flashing in a pattern or open the authorization window via the Nanoleaf mobile app by navigating to device settings and selecting "Connect to API."

Run this function to obtain auth_token during authorization window

from nanocontroller import get_token

get_token(
    ip address,     # Found on back of device, in app, or through network discovery tool 
    port            # Port defaults to "16021", but manual port discovery recommended. 
    )

---

Getting Started

Initializing the NanoController

from nanocontroller import NanoController

nano = NanoController(
    auth_token="sdg7648t24ih"  # Obtained from "get_token"
    ip_address="172.20.7.17",  # Found on the back of the device, in the app, or via a network scan.
    port="16021",              # Default port is 16021. Discovery recommended.
    latitude=28.5383,          # Optional latitude, required for weather functions.
    longitude=-81.3792         # Optional longitude, required for weather functions.
)

or create a .env file

NANO_AUTH_TOKEN=
NANO_IP_ADDRESS=                # Strings
NANO_PORT=

NANO_LATITUDE =                 # Floats
NANO_LONGITUDE = 

and just

from nano import NanoController

nano = NanoController()

Location can be updated at any point after initialization with:

nano.set_location(lattitude, longitude)

Methods

General Controls

• Get states:

  await nano.get_brightness()          # Get current brightness level.
  await nano.get_effect()              # Get the currently active effect.
  await nano.get_effects_list()        # List available effects downloaded in the app.
  await nano.get_state()               # Retrieve all states of the panels.
  

• Set states:

  await nano.set_brightness(50)        # Set brightness (0-100).
  await nano.set_effect("Cocoa Beach")      # Set a specific effect by name.
  

---

Custom Effects

Customize the panel colors and effects programmatically:

await nano.custom(color_dict, loop=True)

• Input Format:

  color_dict = {
      0: [(255, 0, 0, 10)],                     # Panel 1: Changes to Red with a 1-second transition.
      3: [(0, 255, 0, 10), (0, 0, 255, 30)],    # Panel 4: Changes to Green with a 1-second transition, then changes to blue with a 3 second transition. Loops by default, if Loop is False then remains static on blue after transitions
      ...
  }
  

  You can change all panels at once, or partial sets. The keys(0 to (number of panels - 1)) correspond to the set order of the panels. This defaults to "top_to_bottom" but can be changed with:

  nano.panels.bottom_to_top()
  nano.panels.left_to_right()
  nano.panels.right_to_left()
  

  You can use multiple ordering methods when only one would leave room for ambiguity:

  nano.panels.left_to_right()
  nano.panels.bottom_to_top()
  

  You can customize the ordering if the positions do not strictly follow a specific order:

  print(nano.panels)                        # Gets IDs and relative postions        
  
  #Output: [Panel(id=30344, x=0, y=580), Panel(id=26383, x=0, y=464), Panel(id=19622, x=0, y=348), Panel(id=29596, x=0, y=232), Panel(id=11739, x=0, y=116), Panel(id=38168, x=0, y=0)]
  
  nano.panels.custom_sort(ordered_ids)      # ordered_ids is an array of the ids in a customized order, [26383, 19622, 30344, etc...]  
  

---

Timer

Gradually transition panels from one color to another, one by one, over a defined time. Follows the set ordering of panels, defaulting to "top_to_bottom". Accepts an optional function to execute at the end of the timer alongside the ending animation on the panels:

Usage demonstration

await nano.timer(
    duration = 60,                  # Required - Time in seconds (≥ total number of panels).
    start_color = BLUE,             # Default blue.
    end_color = WHITE,              # Default white.
    alarm_length = 10,              # Alarm duration in seconds.
    alarm_brightness = 100,         # Full brightness for the alarm.
    end_animation = None,           # Custom `color_dict` for end effect. Defaults to quckly cycling through random colors.
    end_function = None,            # Optional async function to execute during end_animation
    end_function_kwargs = None      # Arguments for the end function.
)

Application

Weather Visualization

1. Set location:

   await nano.set_location(latitude, longitude)
   

2. Display hourly forecast: Each panel represents an hour. For example:

   • Heavy rain in 3 hours: Panel 3 quickly flashes blues and whites.
   • Overcast: Panel slowly transitions between grey tones.
   • weather_codes.py defines weather animations and can be customized. It is not fully optimized yet so edit it how you like.

   await nano.set_hourly_forecast(
       latitude = None, 
       longitude = None,                # If location has not been set at initialization or with .set_location() it must be provided here
       sunrise = 6,                     # Weather effects varry based on if they occur during day or night. Daytime hours fall within (sunrise, sunset) exclusive. 
       sunset = 18,
   )
   

3. Display precipitation levels:

   

   Sets the panels to display precipitaion level over "hour_interval" periods. Defaults to one hour per panel. Precipitation is represented on a gradient from the brightest blue for 100% chance and yellow for 0%. These colors are customizable. The image above represents (starting from the bottom): 0%, 30%, 60%, 100%, 90%, 25%.

   await nano.set_precipitation(
            hour_interval = 1, 
            latitude = None,                  # Location necesarry if not already set
            longitude = None,
            max_color = BLUE,                 # Many standard colors are predefined
            min_color = YELLOW
    )
   

4. Display temperature gradients:

   

   Sets the panels to display the temperature per hour intervals. Defaults to one hour per panel. Default color gradients defined by the dictionary:

   gradient_dict = {
       0: {
           "start": (255, 255, 255),  # Bright white
           "end": (255, 255, 255)     # Bright white
       },
       40: {
           "start": (255, 255, 255),  # Bright white
           "end": (128, 128, 128)     # Light white
       },
       50: {
           "start": (90, 0, 140),    # darker purple
           "end": (150, 50, 255)      # purple
       },
       60: {
           "start": (0, 0, 255),      # Blue
           "end": (40, 90, 255)       # Slightly lighter blue
       },
       70: {
           "start": (0, 255, 0),      # Green
           "end": (90, 255, 60)       # Yellowish green
       },
       80: {
           "start": (255, 255, 0),    # Yellow
           "end": (255, 0, 0)         # Red
       },
       100: {
           "start": (255, 0, 0),      # Red
           "end": (255, 0, 0)         # Red
       }
   }
   

   Custom gradient dictionary of the same form can be passed to accomadate different climates. Intervals can be customized. "start" defines the color at the lowest point in the interval and "end" defines the color at the highest point in the interval.

   await nano.set_temperature(
           hour_interval = 1,       
           latitude = None, 
           longitude = None, 
           gradient_dict = None,
   )
