Hi,
I have made the HALO air quality sensor and is working just great with home assistant. Now I want the LED ring light up when the CO2 is low (green) medium (orange) or high (red).
is it possible to do this within one single automation and how can I turn off the led when it is within a specific range?
thnx for the help.

You can run the whole world with a single automation if you wanted (, although it would probably be a bad design decision).
You should post some more information, along with code that you’d tried, or the best most people here can do is point you to The Documentation.
thx for the help
I now have this yaml file but I don’t know how to integrate the trigger ID into a specific action:
alias: Light 'Turn on on Halo Air Quality Sensor Halo
description: ""
triggers:
- trigger: numeric_state
entity_id:
- sensor.halo_v1_co2
below: 800
id: low
- trigger: numeric_state
entity_id:
- sensor.halo_v1_co2
above: 801
below: 1100
id: medium
- trigger: numeric_state
entity_id:
- sensor.halo_v1_co2
above: 1091.2
id: high
conditions: []
actions:
- action: light.turn_on
metadata: {}
data:
rgb_color:
- 255
- 38
- 0
transition: 5
target:
entity_id:
- light.halo_v1_halo
mode: single
thnx

I have tested an automation where i have used the choose action for selecting the trigger id:
alias: timer test trigger
description: ""
triggers:
- trigger: time
id: time-1
at: input_datetime.time2trigerevent
- trigger: time
id: time-2
at:
entity_id: input_datetime.time2trigerevent
offset: "00:00:30"
conditions: []
actions:
- choose:
- conditions:
- condition: trigger
id:
- time-1
sequence:
- action: switch.turn_on
metadata: {}
data: {}
target:
entity_id: switch.esp32_s3_relay_6ch_relay_1
- conditions:
- condition: trigger
id:
- time-2
sequence:
- action: switch.turn_off
metadata: {}
data: {}
target:
entity_id: switch.esp32_s3_relay_6ch_relay_1
mode: single

I have just one question and don’t know how to solve this using this config.
I have setup the brightness to 30%
brightness_pct: 30
Now I only want for the red light to have a brightness of 100%, is this something I have to setup in conditions or can It be done in the action itself?
