"""Event entities for the OpenClaw integration.
|
|
|
|
Provides native HA EventEntity entities for:
|
|
- openclaw_message_received — fires on each assistant reply
|
|
- openclaw_tool_invoked — fires on each tool invocation result
|
|
|
|
These complement the raw HA bus events with proper entity-registry entries
|
|
that are selectable in the automation UI (no YAML needed).
