Hassio REST switch - rest

Question

I'm trying to make Home Assistant button/switch, which changes state of my lamp through REST call.
I got set up server with command, which changes state of lamp on 192.168.43.21/lampSwitch and returns json {"state": "ON"} or OFF, based on after-switching state.
I'm facing problem with scripting entities and showing current/returned state in Hassio - acquiring state and changing it via home-screen switch.
My configuration:
# Loads default set of integrations. Do not remove.
default_config:
# Text to speech
tts:
- platform: google_translate
automation: !include automations.yaml
script: !include scripts.yaml
scene: !include scenes.yaml
rest:
- scan_interval: 5
resource: http://192.168.43.21/
sensor:
- name: "Temperatura"
# unique_id: "sensor.temperature_sensor"
json_attributes_path: "$.response.system"
value_template: "{{value_json['temperature']}}"
json_attributes:
- "temperature"
- name: "Wilgotność powietrza"
# unique_id: "sensor.humidity_sensor"
json_attributes_path: "$.response.system"
value_template: "{{value_json['humidity']}}"
json_attributes:
- "humidity"
- name: "Poziom wody"
# unique_id: "sensor.water_sensor"
json_attributes_path: "$.response.system"
value_template: "{{value_json['water']}}"
json_attributes:
- "water"
lamp_switch:
- command: "Lamp switch"
trigger:
platform:
action:
url: http://192.168.43.21/lampSwitch/
I saw solution which uses cURL and command line, but I couldn't find any suiting example.
Note that the rest entities works just fine (shows up at home screen).
Thank you in advance

I use this to launch applications on my Samsung TV. I define my_command in Configuration.yaml, then use:
/bin/bash -c "/usr/bin/curl -X POST 'http://<<My_IP>>:8001/api/v2/applications/'{{ variables.my_command }}"
I call this from a button and pass a variable that defines the application that I want.
I hope this helps.
