[Share] Festive Christmas Porch Lights with RGB bulbs

I’m just sharing a little Appdaemon script I came up with. I’m a bit proud, as this is my first Python script (ever), but also thought it may help others.

The hardware: I have two BR30 (can-style) front porch lights, into which I recently installed two OSRAM Lightify RGB BR30 bulbs connected to their gateway.

The challenge: In a few weeks, our Christmas decorations will go up, and my wife asked me if I could make our house a bit more festive by having the porch lights toggle between red and green.

I looked into doing this with normal HASS automation, but it seemed tricky, and I’ve been wanting to get my feet wet in Python and Appdaemon anyway.

Here’s the setup:

  • When the holiday light switch is switched on (which is an outdoor GE ZWAVE switch that goes to the string lights, inflatable Santa, etc), begin the red/green sequence, changing the color every 2 seconds (red for 2 seconds, then green for 2 seconds, etc).

  • When the holiday light switch is turned off (usually midnight), return the porch lights to soft white light (2700k) until a normal HASS automation turns them off just before sunrise.

I have both the individual bulbs in a group (group.porch_group).

It may not be the cleanest way to do this, but it does work. Hope it helps and comments welcome.

import appdaemon.appapi as appapi

class XmasPorchLights(appapi.AppDaemon):

  def initialize(self):
    self.showover = 0
    self.listen_state(self.StartSequence, "switch.holiday_lights_switch")

  def StartSequence(self, entity, attribute, old, new, kwargs):
    if new == "on" :
      self.showover = 0
      self.run_in(self.ChangeToRed, 1)
    if new == "off" :
      self.showover = 1
  def ChangeToRed(self, kwargs):
    if self.showover == 0:
      self.turn_on("group.porch_group", rgb_color = [255 , 0 , 0], brightness = 255)
      self.run_in(self.ChangeToGreen, 2)
      self.turn_on("group.porch_group", kelvin = "2700", brightness_pct = 100)
  def ChangeToGreen(self, kwargs):
    if self.showover == 0:
      self.turn_on("group.porch_group", rgb_color = [0 , 255 , 0], brightness = 255)
      self.run_in(self.ChangeToRed, 2)
      self.turn_on("group.porch_group", kelvin = "2700", brightness = 255)


Sorry for my ignorance but how do i use this??

It runs in AppDaemon. I run AppDaemon as a separate Docker container.
