WLED 0.13.x LED Controller Home Assistant Revive

Got an old WLED controller stuck on version v0.13.x, or any version below v0.14.0? Don’t worry.. your trusty little device isn’t destined for the junk drawer just yet! Even though those 1MB flash controllers can’t handle the latest WLED updates, there’s a fun and creative way to make those unsupported controller work seamlessly with the latest Home Assistant versions. In my case i have "7" unsupported controllers stuck at v0.13.1 and v0.13.3, so making them work again in Home Assistant was a win.

Updates:

• 24 Dec 2024: now working as two way communication using HTTP Polling. See step 7.
• 14 Jan 2025: effect list fixed: removed newer effects that do not exist in wled v0.13.1.

Working features:

• on
• off
• change color
• change brightness
• change effect

Tested on WS2812b LED

---

Lets say we want our new light name to be light.wled_desk_led start by doing the following:

1 - Preparations

• Make sure to remove the unsupported led's from Wled integration.

• If not already, start by creating those files in Home Assistant root directory rest_command.yaml, lights.yaml, input_select.yaml

• include them in your configuration.yaml:

input_select: !include input_select.yaml
rest_command: !include rest_command.yaml
light: !include lights.yaml

• To make thing easy, use a text editor (Find & Replace All) tool to replace the word desk and Desk with the name you want. make sure to replace it everywhere and to double check, before coming yalling at me ;-)

• You have to do all the steps below for EVERY controller you have.

2 - Create a rest command to communicate with WLED controller:

• paste the rest command to your rest_command.yaml
• replace ip with your conroller ip

rest command

  wled_desk_led:
    url: "http://10.0.0.107/win&T={{ on }}&A={{ brightness }}&R={{ red }}&G={{ green }}&B={{ blue }}{% if effect is defined %}&FX={{ effect }}{% endif %}"

3 - Create a light template:

• paste this to your lights.yaml

light template

  - platform: template
    lights:
      wled_desk_led:
        friendly_name: "WLED Desk LED"
        value_template: "{{ states('input_boolean.wled_desk_led_state') == 'on' }}"
        level_template: "{{ states('input_number.wled_desk_led_brightness') | int }}"
        effect_list_template: "{{ state_attr('input_select.wled_desk_led_effect', 'options') }}"
        effect_template: "{{ states('input_select.wled_desk_led_effect') }}"
        rgb_template: >
          ({{ states('input_number.wled_desk_led_red') | int }},
           {{ states('input_number.wled_desk_led_green') | int }},
           {{ states('input_number.wled_desk_led_blue') | int }})
        turn_on:
          service: script.wled_desk_led_active
          data:
            brightness: "{{ states('input_number.wled_desk_led_brightness') | int }}"
            red: "{{ states('input_number.wled_desk_led_red') | int }}"
            green: "{{ states('input_number.wled_desk_led_green') | int }}"
            blue: "{{ states('input_number.wled_desk_led_blue') | int }}"
        turn_off:
          service: script.wled_desk_led_off
          data:
            brightness: "{{ states('input_number.wled_desk_led_brightness') | int }}"
            red: "{{ states('input_number.wled_desk_led_red') | int }}"
            green: "{{ states('input_number.wled_desk_led_green') | int }}"
            blue: "{{ states('input_number.wled_desk_led_blue') | int }}"
        set_level:
          service: script.wled_desk_led_active
          data:
            brightness: "{{ brightness }}"
        set_rgb:
          service: script.wled_desk_led_active
          data:
            brightness: "{{ states('input_number.wled_desk_led_brightness') | int }}"
            red: "{{ r }}"
            green: "{{ g }}"
            blue: "{{ b }}"
        set_effect:
          service: script.wled_desk_led_effect
          data:
            effect: "{{ effect }}"

4 - Create those 3 scripts:

those scripts are used to pass rest commands to your controller. Paste them to your scripts.yaml.

script 1 - On/activities

5 - Create the following Helpers

We use those to save and retain the different states of the lights like: On, Off, Brightness, RGB colors values and last effect..

Hellpers

input_boolean:
  wled_desk_led_state:
    name: WLED Desk Led State

input_number:
  wled_desk_led_brightness:
    name: WLED Desk Led Brightness
    min: 0
    max: 255
    step: 1

  wled_desk_led_red:
    name: WLED Desk Led Red
    min: 0
    max: 255
    step: 1

  wled_desk_led_green:
    name: WLED Desk Led Green
    min: 0
    max: 255
    step: 1

  wled_desk_led_blue:
    name: WLED Desk Led Blue
    min: 0
    max: 255
    step: 1

6 - We need one more helper for effects:

this one we will create as yaml as it will take so much time to create in the ui.

• add this to input_select.yaml

7 - Polling states from the controller (optional).

to make this method works as 2 way communication (changes using wled app/ui reflect to Home Assistant), we will implement http polling, which will let us poll the states of the controller every x time. In my case i set the interval at 5 seconds.

• add polling logic to your sensors.yaml
• replace controller ip address with yours.

Polling logic

  - platform: rest
    name: "WLED Desk Poll"
    resource: "http://10.0.0.107/json/state"
