Home Automation systems

It is possible to interface WLED with home automation systems and other 3rd party software. You can use any API WLED provides (JSON, HTTP, UDP, MQTT), JSON is preferred. This page is intended for sample code and configs others use to control WLED from various 3rd party software:

HomeAssistant

Connection is made via MQTT. In the latest binary, auto-discovery is possible. In case you want to configure the device manually:

light:
  - platform: mqtt
    name: "Kitchen Floor Lights"
    command_topic: "wled/all"
    brightness_command_topic: "wled/all"
    rgb_command_topic: "wled/all/col"
    rgb_command_template: "{{ '#%02x%02x%02x' | format(blue, green, red)}}"
    effect_command_topic : "wled/all/api"
    effect_list:
    - "FX=0"
