Control tree over IoT

[meatalhead]

I'm trying to make my RGB tree into a webthing to use with Mozilla IoT, https://github.com/mozilla-iot/webthing-python. I've tried to set the tree off using threading with a common boolean that the IoT can control to turn the tree on and off. The tree code works fine on it's own but when run it as a thread I get the following:

gpiozero.exc.GPIOPinInUse: pin 8 is already in use by <gpiozero.PWMLED object on pin GPIO8, active_high=True, is_active=False>

Here's my code, my python's pretty poor but any help would be great.

from __future__ import division, print_function
from webthing import (Action, Event, Property, SingleThing, Thing, Value, WebThingServer)

from gpiozero import LEDBoard
from gpiozero.tools import random_values

tree = LEDBoard(*range(2,28),pwm=True)
tree_on = True
tl = RGBXmasTree(brightness=0.2)
colors = [Color('red'),Color('green'),Color('blue'),Color('yellow')]
tl.color = (0.5,0.5,0.5)

def random_color():
    r = random.random()
    g = random.random()
    b = random.random()
    return(r,g,b)

def rgb():
    print('rgb')
    for sequence in range (1,50):
        for color in colors:
            tl.color = color
            sleep(3)

def onebyone():
    print('onebyone')
    for sequence in range(1,20):
        for color in colors:
            for pixel in tl:
                pixel.color = color

def hue():
    print('hue')
    tl.color = Color('red')
    for sequence in range(1,200):
        tl.color += Hue(deg=1)

def sparkle():
    print('sparkle')
    for sequence in range(1,80):
        pixel = random.choice(tl)
        pixel.color = random_color()
        #sleep(0.1)

def tree_thread():
    print('Running tree thread')
    while tree_on:
        for sequence in range(1,6):
            if sequence == 1:
                sparkle()

            if sequence == 2:
                hue()

            if sequence == 3:

You've initialised two devices:

tree = LEDBoard(*range(2,28),pwm=True)

and:

tl = RGBXmasTree(brightness=0.2)

I guess you only want one of these?

Sorted thanks
