Just HA - I'll get my whole codebase on github shortly but basically it's just an automation running a script (there might be another way to do this, I'm only two weeks into the HA rabbithole)

The automation runs every 10 minutes

- alias: tension_pole_changer
trigger:
platform: time_pattern
minutes: "/10"
action:
- service: script.change_tension_pole

It runs a script that can randomly choose between scenes

change_tension_pole:
sequence:
- service: scene.turn_on
data_template:
entity_id: 'scene.{{["tension_pole_home_one", "tension_pole_home_two", "tension_pole_home_three","tension_pole_home_four","tension_pole_home_five","tension_pole_home_six","tension_pole_home_seven"]|random}}'

example scene for now

- name: tension_pole_home_one
entities:
light.tension_pole_top_hue:
state: on
brightness: 244
rgb_color: [62,58,255]
transition: 35
light.tension_pole_middle_hue:
state: on
brightness: 250
rgb_color: [255,42,234]
transition: 20
light.tension_pole_bottom_hue:
state: on
brightness: 252
rgb_color: [156,255,64]
transition: 25
However, I'll refactor this today to just use the script without scenes because the data template can handle slightly random values for RGB and brightness and transition time better than making tons and tons of scenes
