FAQ
Questions about Check HA Config.
What does the Check HA Config action do in Home Assistant?
Validates the YAML config without reloading. Useful for "after editing config → confirm valid before reload" maintenance workflows.
What inputs does Check HA Config require?
Check HA Config 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 Check HA Config support batch operations?
Yes. Run Check HA Config inside a Loop node to process arrays. Tiny Command handles Home Assistant's rate limits automatically so you don't have to throttle manually.
