Home Assistant + Xiaomi Yeelight + MQTT

Configuration
2

I’ve decided to use automations with mqtt triggers and now it works correctly with this type of setup

  • id: light-mqtt-turn-on
    alias: Kitchen Light MQTT Turn On
    trigger:
    platform: mqtt
    topic: /home/light
    payload: “on”
    encoding: “utf-8”
    action:
    service: light.turn_on
    entity_id: light.kitchen

  • id: light-mqtt-turn-off
    alias: Kitchen Light MQTT Turn Off
    trigger:
    platform: mqtt
    topic: /home/light
    payload: “off”
    encoding: “utf-8”
    action:
    service: light.turn_off
    entity_id: light.kitchen

Can you help me to understand if it is possible to make this kind of messages in this chain “hass - mqqt broker - web app”

I send from webapp something like /home/light status and home assistant returns status (on or off) on my light?

Thanks!
