Configuration

This node takes no configuration beyond its connection.

Output

One shape.

result

Field	Type	Example
result Home Assistant's verdict: 'valid' or 'invalid'.	string	—
valid True when the verdict is 'valid'.	boolean	—
errors The validation errors, or null when there are none.	string	—

{
  "errors": "",
  "result": "",
  "valid": false
}

Notes

Safe to run against a live instance: it validates the configuration and changes nothing.
Home Assistant requires an admin token for this call; a non-admin long-lived token fails with 401 even though the connection tests green.
