So I’ve written this app specifically for my LIFX lights at home but there are some things that I’m not really across.
It’s works fine so far, I got sick of having to pass meaningless numbers to change my lights to a certain setting. I like to have it as it’s laid out in the LIFX app where brightness’s are in percentage and color_temp’s are in the K values.
I also added in a pulsing feature for light notifications.
Questions:
- How can I use this app within other apps using AppDaemon? imports and use etc. I’ve given it a go and couldn’t get it working.
- How can I make multiple entity_id’s passed to the app run simultaneous? This is only an issue for the pulsing because I’ve got a delay in between state transitions. I’d like to be able to send multiple lights through to the app and them all pulse at the same time to notify if someone is at the front door or whatever else can be dreamed up.
- This is my first app, so any tip or tricks would be appreciated!
- Oh and for some reason when I sent a color_temp under 153.85 it wouldn’t work, however that’s the state value that was in HA when changed the lights using the LIFX app? Perhaps it’s something to do with the rgb_color value?

# Comments:
#
# App to easily turn on LIFX lights with brightness, color_temp and rgb_color variables. Also allows light pulsing
# to use for notification triggers.
#
# Args:
#
# entity_id = entity_id of light to be turned on. You can send multiple entities
# eg. light.study or light.study,light.lounge
# brightness = light brightness in percentage
# eg. 100
# default: 75
# color_temp = light color temp
# eg. neutral or 3200
# default: neutral
# rgb_color = light rgb color
# eg. red or 255,0,0
# default: white
# pulse_count = pulse cycles to pulse between the original light states and the ones specified above. If the light is
# already off the light will pulse between passed variables and off state.
# eg. 2
# default: 0 - which is no pulse
# pulse_time_on = time in seconds to pulse on
# eg. 1 or 1.5
# defaults: 1 second
# pulse_time_off = time in seconds to pulse off
# eg. 1 or 1.5
# default: 1 second
#
