Add transition_length in servo.write

[Coninox]

Describe the problem you have/What new integration you would like

It would be nice if we could set the transition_length parameter in the servo.write action. We could have the ability to have different rotation speed in different cases.

Please describe your use case for this integration and alternatives you've tried:

For example:

api:
  services:
    - service: control
      variables:
        level: float
    transition_lenght: string
      then:
        - servo.write:
            id: my_servo1
            level: !lambda 'return (-2*(level/255))+1;'
        transition_lenght: !lambda 'return transition_lenght;'

switch:
  - platform: template
    name: boule_ch2
    restore_state: true
    optimistic: true

    turn_on_action:
      - servo.write:
          id: my_servo1
          level: -1
          transition_length: "00:00:10"

    turn_off_action:
      - servo.write:
          id: my_servo1
          level: 1
          transition_length: "00:00:40"

+1 This would be really great!

It is not very intuitive, but I found that you can set the transition length using a lambda call. - lambda: |- servo_id->set_transition_length(5000);

where servo_id is the id you set in the servo component definition under id:. This workaround is good enough for me for now.

@narolinus can you elaborate a little more on your work around? I'm trying to control both the level and the transition_length of a servo via the API and Input_number helpers from Home Assistant. I'm able to control the level without issue but can't figure out how to control the transition_length outside of hard coding it in the ESPhome config. Would you mind sharing more of your config?
