Anyone found a way?
I have tried the LVGL v8 (which I believe is what ESP-Home uses) method Label scroll speed in LVGL 9 - How-to - LVGL Forum

And as found out it should be used in a lambda on_boot. :man_shrugging:
Has anyone found a way to make it scroll faster?

lvgl:
  on_boot:
    - lambda: |-
        lv_obj_set_style_anim_time(id(text1), 800, LV_PART_MAIN);
  id: my_lvgl
