You’re such a bad ass! Thank you so much, couldn’t have spotted that in a hundred years!
Edit: This is a workaround for setting an effect on Tasmota Magic Home LED. By change you know how to let this loop for about a minute, it only changes once now… Cant seem to find any guides, saw another post of yours but not really apliccable in my case.
You want it to change colour every few seconds for a minute? If so, how random do you want it to be? Like does it always go red, yellow, blue, green, purple but just the start color is different each time? Or is the first colour based on something? Or do you just want a completely random colour every time?
Well it really doesnt matter, id like to use it in my alarm setup to draw attention so it just has to switch fast until the state of the alarm is disarmed, or as lomg as its triggered.
I tried the snippit from above followed by turn off an then copied that like 100 times, didnt work and ofcourse a nasty workaround.
Thanks for your help!

maybe my party lights script helps:
lights_partying_on:
alias: Lights partying on
sequence:
service: light.turn_on
data_template:
entity_id: light.{{['dining_corner','cabinet','kist','home_theater']|random}}
rgb_color: ['{{ (range(0, 255)|random) }}',
'{{ (range(0, 255)|random) }}',
'{{ (range(0, 255)|random) }}']
brightness: '{{ (range(50, 250)|random) }}'
transition: '{{ (range(1, 3)|random) }}'
call this with the following automation each 4 seconds:
automation:
- alias: 'Lights partying'
id: 'Lights partying'
initial_state: 'off'
trigger:
platform: time
seconds: '/4' # {{ "/" ~ ((range(2, 5) | random) | int) }}
condition:
condition: template
value_template: >
{{is_state('automation.sense_lights_change','off') }}
action:
service: script.lights_partying_on
and this input_boolean for setting the mode:
- alias: 'Lights Party Mode'
id: 'Lights Party Mode'
initial_state: 'on'
trigger:
platform: state
entity_id: input_boolean.home_mode_party
action:
service_template: >
script.lights_mode_party_{{ trigger.to_state.state }}OK, off the top of my head I would probably do it like this:
automation:
- alias: Police
trigger:
- platform: state
entity_id: alarm_control_panel.house
to: 'triggered'
action:
- service: script.light_cycle
- delay: '00:01:00'
- service: homeassistant.turn_off
entity_id:
- script.light_cycle
- script.loop_lights
script:
light_cycle:
sequence:
- service: homeassistant.turn_on
entity_id: group.all_lights
data_template:
brightness: 250
color_name: >
{% set colors = ['red', 'yellow' , 'blue', 'green' , 'purple'] %}
{{ colors|random }}
- service: script.loop_lights
loop_lights:
sequence:
- delay: '00:00:02'
- service: script.light_cycle
Fairly simple, but does the business.
cool this loop. you’re a magician!
—> Cookbook this goes.
Super!! thanks mate!
is there a way to use mili seconds instead of seconds? To have it change the color faster perhaphs?
Thanks again!
Edit: got the miliseconds now, but it still doesnt loop, it turns on and does not change just once.

action:
- service: light.turn_off
entity_id: group.all_lights
- service: script.light_cycle

trigger:
- platform: state
entity_id: alarm_control_panel.house
to: 'disarmed'
action:
- service: homeassistant.turn_off
entity_id:
- script.light_cycle
- script.loop_lights
Any advice?
The problem is that when you’re looping, if the first script is still running when the second one tries to start it again then everything stops. So by bringing the time down to milliseconds, your lights are probably still changing colour from the last go, so the script is still running, so it stops.
I suppose you could try stopping the first script before restarting it.
Good one, it loops alright now. but not as fast as i want. Could also be that it are mqtt lights?

In fairness, I bet if you stand over the road in the dark and trigger this it will still be pretty eye-catching 
Haha, nice one. Yeah indeed, I’ll tinker on for a bit to tweak it. I’m glad it works so far with your help. Thanks a bunch my friend!
No worries 
I like the concept of these party light animations. But I cant trace the linkages between the input_boolean, the script and the automation? (their seems to be missing scripts?)
Do you have a link to your package yaml?
sure, here you go. Please note the input_boolean.home_mode_party isn’t in here, because it is triggering some other things too, its in a another package, but nothing fancy, just:

I love this concept… Thanks for sharing
I 'm trying to modify it to only flicker red and blue lights in order to simulate police lights.
This kind of flickers the red and blue but it is mixed in with gentle transitions of yellow green blue red and purple.

HI Team
I get the error - not a valid value for dictionary value @ data[‘action’][0][‘entity_id’]
I can see in the sample before a data_template is used, but can I do what I’m trying in an automation - so selecting randomly between a few ligths…
/Joern
think you need to change it to:
entity_id: >
light.{{['hue_color_lamp_1','hue_color_lamp_2'] | random }}
or use quotes:
entity_id: "light.{{['hue_color_lamp_1','hue_color_lamp_2'] | random }}"
not sure about the latter though, I use the former (now)… this is an old post
lights_partying_on:
alias: Lights partying on
mode: restart
sequence:
service: light.turn_on
data:
entity_id: >
light.{{['frontdoor','dining_corner',
'lounge_chair_long','home_theater','world_map']|random}}
rgb_color: >
{{[range(0,255)|random,range(0,255)|random,range(0,255)|random]}}
brightness: >

thank you.
Works perfectly.
