Smooth matter dimming

[buoyant ember]

Hi,

I am trying to dim a matter bulb with a matter light switch, both connected to HA.

The problem is, the dimming is really jumpy and I cannot seem to fix it. I am trying to make it so that when I hold down a button, the brightness increases. I cannot seem to make it smooth without making it take ages to increase the brightness, the only way it looks smooth is if it takes 30 seconds to increase.

Does anyone know how I may be able to fix this?

Thanks in advance.

How does your current automation work?

Also, how does the button report in HA - is it a switch that just goes on when you press it, or is it a button with an event_type: held or something?

I use a similar automation and I make 5% increases while holding the button. Zigbee in my case but I don't think that matters 🤷‍♂️

yeah - if you're relying on the switch to output "button is being pressed, still being pressed, still being pressed etc" i could see it being jerky, but "trigger when switch is pressed, loop until it stops being pressed" is a much more robust way of doing it

I am using an IKEA BILRESA switch connected via matter.
It just shows as single click, double click, held, released after held.

I was using the Turn On: Light function and changing different brightness steps and transitions to try and make it fast but smooth but I can never get both.

Changing brightness works fine for my Zigbee bulbs and switches but seems to work completely differently when I use matter for some reason.

can you post your automation that you've tried (in yaml form as a code block ``` before and after)

Im using a blueprint for the switch I am using to control the lights but I will post

  - variables:
      trigger_id: "{{ trigger.id }}"
      press_type: "{{ trigger.to_state.attributes.event_type }}"
      button1_max_iterations: 100
      button2_max_iterations: 100
  - parallel:
      - repeat:
          while:
            - condition: template
              value_template: >
                {{ press_type == 'long_press' and trigger_id == 'button1' and
                states(trigger.entity_id) == trigger.to_state.state }}
            - condition: template
              value_template: |
                {{ repeat.index|default(0) <= button1_max_iterations }}
          sequence:
            - sequence:
                - action: light.turn_on
                  metadata: {}
                  target:
                    entity_id: light.bedroom_lights
                  data:
                    brightness_step_pct: 7
                    transition: 0.1```

I think that is the part responsible for light dimming, i have brighness step set to 7, transition set to 0.1 and scrolling interval set to 0.1

[rare robin]

is there a wait in there as well?

[buoyant ember]

What do you mean by that?

[rare robin]

i mean did you copy everything over, or just selectively copy a bit of it?

[buoyant ember]

I just copied a part of the entire automation for that switch.

[rare robin]

ok, can you copy the whole thing then?

Sorry about that, it is too long for discord so i pasted it here: https://pastebin.com/1z3sGhYg

the conditions are weird - you can add not_to/not_from filters to the triggers to ignore unknown/unavailable, and {{ trigger.from_state.state != trigger.to_state.state }} should always be true for a state trigger...

it all looks sensible otherwise. i guess the only thing might be a limitation on the bulb? what happens if you set it to like 10% and then send an action from the developer tools tab to go to 90% over 5s?
it might be that a 0.1s transition is too small for the fw on the bulbs
