FAQ
Questions about List HA Event Types.
What does the List HA Event Types action do in Home Assistant?
Returns the event types Home Assistant's event bus is configured to emit. Useful for "what events can I subscribe to" introspection at workflow-build time.
What inputs does List HA Event Types require?
List HA Event Types has no required inputs. Sensible defaults are applied if you leave fields blank.
Can I use dynamic inputs from earlier workflow nodes?
Yes. Any field on this action can pull values from upstream nodes, whether that's a form response, a trigger payload, an AI output, or a lookup result.
What happens if Home Assistant returns an error?
The workflow pauses on the failed node, the error message is captured in the run log, and you can retry the run with one click. Auto-retry policies are configurable per workflow with exponential backoff up to 5 attempts.
Does List HA Event Types support batch operations?
Yes. Run List HA Event Types inside a Loop node to process arrays. Tiny Command handles Home Assistant's rate limits automatically so you don't have to throttle manually.
