HA Light Controller

HA Light Controller adds state verification and automatic retries to light commands. When you call light.turn_on, Home Assistant sends the command once and assumes success. This integration verifies that entities actually reached the target state and retries if they didn't.

This solves the common problem of lights occasionally missing commands due to network congestion, Zigbee/Z-Wave mesh issues, or unresponsive devices. Instead of building retry logic into every script and automation, HA Light Controller handles verification centrally with configurable tolerances and backoff strategies.

How It Works

1. Sends the light command (on/off, brightness, color, etc.)
2. Waits a configurable delay for the state to update
3. Verifies entity attributes match target values within tolerance
4. Retries with exponential backoff if verification fails
5. Optionally logs success to the Home Assistant logbook

Key Features

• State verification - Confirms entities reached target brightness, color, and temperature within configurable tolerances
• Automatic retries - Configurable retry attempts with exponential backoff
• Group expansion - Automatically expands light.* and group.* entities to individual lights
• Per-entity overrides - Set different attributes for each light in a single service call via the targets parameter
• Presets - Store light configurations as button entities for one-tap activation

Installation

HACS

1. Add https://github.com/L3DigitalNet/HA-Light-Controller as a custom repository (Integration)
2. Install "HA Light Controller"
3. Restart Home Assistant

Manual

1. Copy custom_components/ha_light_controller to your config/custom_components/ directory
2. Restart Home Assistant

Removal

1. Go to Settings → Devices & Services → Light Controller
2. Click the three-dot menu → Delete
3. Restart Home Assistant
4. (Optional) Remove the custom_components/ha_light_controller directory

All preset entities (buttons and sensors) are automatically removed when the integration is deleted.

Configuration

Add the integration via Settings → Devices & Services → Add Integration → "Light Controller".

Configuration options include default brightness, transition time, verification tolerances (brightness, RGB, Kelvin), retry settings, and success logging.

Usage

Basic Service Call

service: ha_light_controller.ensure_state
data:
  entities:
    - light.living_room_ceiling
    - light.living_room_lamp
  state: 'off'

Per-Entity Overrides

service: ha_light_controller.ensure_state
data:
  entities:
    - light.ceiling
    - light.lamp
  brightness_pct: 50
  targets:
    - entity_id: light.ceiling
      brightness_pct: 100
      color_temp_kelvin: 4000
    - entity_id: light.lamp
      brightness_pct: 30
      rgb_color: [255, 200, 150]

Presets

Create and edit presets via the integration options UI or programmatically. The UI supports per-entity configuration - set different brightness, color, and state for each light in the preset. Preset deletion includes a confirmation step.

service: ha_light_controller.create_preset
data:
  name: 'Movie Night'
  entities:
    - light.living_room
    - light.tv_backlight
  brightness_pct: 20
  color_temp_kelvin: 2700

Each preset creates a button.* entity for activation and a sensor.* entity for status tracking.
