Cobra's Presence Central is awesome. This is like a "Lite" version, stripped down for my most common use case of "My presence sensor is only 90% reliable when I drive up to my house. How can I make it respond faster?"
That's what I found with any kind of geofencing presence on my iPhone. On arrival, it would trigger quickly 90% of the time. But 10% of the time, I'd be awkwardly waiting and it would take up to a minute to trigger. By using Combined Presence along with my https://community.hubitat.com/t/release-iphone-wifi-presence-sensor/9075/47 sensor, I can fill in that last 10%.
