How to configure Dim Light properly - looking for best approach

Configuration
1

Hi all,

I’m using ELKOEP automation at home. I configured one sample light already, but I’m not sure if this is proper way. I wish to create ELKOEP integration as a next step as well.

Now what I have and this is working. First I defined RESTfull Sensor which allows me to see STATUS of my LED light. For a status there is URL address in format:

http://192.168.x.x/api/devices//state

# Sensors
sensor:
 
  # RESTful senzor test
  - platform: rest
    name: JSON LAB
    json_attributes:
      - automat
      - brightness
    resource: http://192.168.90.10/api/devices/33633/state
    value_template: '{{ value_json.brightness }}'
    verify_ssl: false
  - platform: template
    sensors:
      auto:
        friendly_name: 'Automat'
        value_template: '{{ states.sensor.json_lab.attributes["automat"] }}'
      bright:
        friendly_name: 'Jas'
        value_template: '{{ states.sensor.json_lab.attributes["brightness"] }}'

Then I defines REST Command because my devices have to use PUT syntax. It returns JSON data with several attributes - brightness attribute is most important.

rest_command:
   led_brightness:
     url: http://192.168.90.10/api/devices/33633
     method: PUT
     payload: '{"brightness": {{ bright }} }'
     content_type:  'application/json; charset=utf-8'
     verify_ssl: false

Then I defined LED Template to control LED light and for STATUS update I’m using REST Sensor. I think there is some better way then to use SENSOR. Is it ???

light:
  - platform: template
    lights:
      elkoep_led:
        friendly_name: "ElkoEP LED light"
        value_template: "{{not is_state_attr('sensor.json_lab', 'brightness', 0) }}"
        level_template: "{{((states('sensor.json_lab') | int)*255/100) | int }}"
        turn_on:
          - service: rest_command.led_brightness
            data_template:
              bright: >
                {{ 100 }}
        turn_off:
          - service: rest_command.led_brightness
            data_template:
              bright: >
                {{ 0 }}
        set_level:
          - service: rest_command.led_brightness
            data_template:
              bright: >
                {{ (brightness /255*100) | int }}

Any idea how to do improve it? Or how to create my own integration? I believe there should be some very similar devices like ElkoEP (www.elkoep.com) so I can use this code as a sample. Any experienced user here can help please?
