The method is only ever called with a tuple of values for intervals. So it's safe to remove this check here and simplify the typing.

core/homeassistant/components/duckdns/__init__.py

Lines 61 to 68 in 7a6dca0

	intervals = (
	INTERVAL,
	timedelta(minutes=1),
	timedelta(minutes=5),
	timedelta(minutes=15),
	timedelta(minutes=30),
	)
	async_track_time_interval_backoff(hass, update_domain_interval, intervals)
