How to read and write servo position in automations. I use ESPHOME, vemos D1 mini and SG-90 servos

Hi,
I’m working on some project where i use servos to controll hot air distribution.
I got it working but for any automations I need to read the servo position.
I use typical code from manual:
https://esphome.io/components/servo.html
I also have read this topic:
https://community.home-assistant.io/t/servo-motor-wont-work-in-esphome/429297
where DivanX10, managed that, but his code is overingeeniered for me. I don’t need start and end position to setup.
I use full 180 degree movement of servo and I need to reed this possition.

Now I can change servo position by lovelace slider (number function),
but i need some automations where I can check servo position and set it’s position by command or even better in Node Red
This is where i need Your help

In my project I use 4 servos and one relay. Code looks like that:

  board: d1_mini

Looks like the code you already found will do it.

So how to check servo state in automation or Node Red?
