 - **entity_id**: Entity IDs of watched device tracker devices. Can be a single entity ID, a list of entity IDs, or a string containing multiple entity IDs separated by commas.
 - **name**: Object ID (i.e., part of entity ID after the dot) of composite device. For example, `NAME` would result in an entity ID of `device_tracker.NAME`.
-- **require_movement** (*Optional*): `true` or `false`. If `true`, will skip update from a GPS-based tracker if it has not moved. Specifically, if circle defined by new GPS coordinates and accuracy overlaps circle defined by previous GPS coordinates and accuracy then update will be ignored.
+- **require_movement** (*Optional*): `true` or `false`. Default is `false`. If `true`, will skip update from a GPS-based tracker if it has not moved. Specifically, if circle defined by new GPS coordinates and accuracy overlaps circle defined by previous GPS coordinates and accuracy then update will be ignored.
 - **time_as** (*Optional*): One of `utc`, `local`, `device_or_utc` or `device_or_local`. Default is `utc` which shows time attributes in UTC. `local` shows time attributes per HA's `time_zone` configuration. `device_or_utc` and `device_or_local` attempt to determine the time zone in which the device is located based on its GPS coordinates. The name of the time zone (or `unknown`) will be shown in a new attribute named `time_zone`. If the time zone can be determined, then time attributes will be shown in that time zone. If the time zone cannot be determined, then time attributes will be shown in UTC if `device_or_utc` is selected, or in HA's local time zone if `device_or_local` is selected.
