How to reduce brightness during 2-5 in the night

Configuration
1

Greetings,

I’ve got a light in a room and I would like to turn it on, triggered by a motion sensor. This was more or less simple.

Now I would like to adjust the brightness based on the time:
16h-02h: 100%
02h-05h: 50%
05h-09h: 100%

I’ve created three automations and it works … but it feels somehow clumsy.

Is there a better way to create a sensor or similar to get it done?

Thanks in advance,
Fridolin

look into the “choose:” option for the automation. It’s in the script documentation on the HA site.

basically you can set the automation to run different actions in the same automation based on different conditions.

Thanks a lot. I’ve been using the UI based wizard and there having if/elseif/…/then is not supported …or at least I cannot see something like that.

But the script syntax is allowing that, so I’ll give that a try.

So you are saying that the “choose:” function isn’t an option in the automation UI editor but it is in the script UI editor?

That’s one of the reasons I never use the UI editors. IMHO (along with many others), it’s always better to do it by hand.

You will learn a lot more that way and you don’t have to worry about the inherent limitations and idiosyncrasies of those editors.

I’ve managed to get to what I wanted by directly adding the code to the automations.yaml:

  trigger:
  - platform: state
    entity_id: binary_sensor.0x00158d000450bc35_occupancy
    to: 'on'
  action:
  - choose:
    - conditions:
      - condition: time
        after: '16:00'
        before: 02:00
      sequence:
      - service: homeassistant.turn_on
        data:
          transition: 2
          brightness_pct: 100
          entity_id: light.0x001788010940bf8d_light
    - conditions:
      - condition: time
        after: 02:00
        before: 05:30
      sequence:
      - service: homeassistant.turn_on
        data:
          transition: 2
          brightness_pct: 15
          entity_id: light.0x001788010940bf8d_light
    - conditions:
      - condition: time
        after: 05:30
        before: 09:00
      sequence:
      - service: homeassistant.turn_on
        data:
          transition: 2
          brightness_pct: 100
          entity_id: light.0x001788010940bf8d_light
    default:
    - service: homeassistant.turn_off
      entity_id: light.0x001788010940bf8d_light
      data:
        transition: 2
  mode: single

I guess, the service execution can be implemented in a more elegant way, but at least I reduced the amount of single Automations.

btw: after manually adapting the yaml, the UI is also showing ‘options’. I don’t know, how they’ve gotten there, but now it is possible to add even more options using the wizard.
