Device_tracker see service

Hi.
Would like to force device trackers to scan the reachability of a series of devices if the do?or is open, and repeat the same thing after few minutes (to determine if device is at home or not).
I’ve seen a device_tracker.see service in the front end, is this the way to do something like this?

Correct, put the device_tracker in your conf and devices in trusted network will begin scanning
