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.

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

• 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
