Device tracker entity
A device tracker is a read-only entity that provides presence information. There are two types of device tracker entities, a ScannerEntity and a TrackerEntity.
ScannerEntity
A ScannerEntity reports the connected state of a device on the local network. If the device is connected the ScannerEntity will have state home and if the device is not connected the state will be not_home.

Properties
Properties should always only return information from memory and not do I/O (like network requests). Implement update() or async_update() to fetch data.
| Name | Type | Default | Description |
|---|---|---|---|
| battery_level | int | None | None | The battery level of the device. |
| hostname | str | None | None | The hostname of the device. |
| ip_address | str | None | None | The IP address of the device. |
| is_connected | bool | Required | The connection state of the device. |
| mac_address | str | None | None | The MAC address of the device. |
| source_type | SourceType | SourceType.ROUTER | The source type of the device. |
DHCP discovery
If the device tracker source_type is router and the ip_address, mac_address, and hostname properties have been set, the data will
speed up DHCP discovery as the system will not have to wait for
DHCP discover packets to find existing devices.
TrackerEntity
A TrackerEntity tracks the location of a device and reports it either as a location name, a zone name or home or not_home states. A TrackerEntity normally receives GPS coordinates to determine its state. Either location_name or latitude and longitude should be set to report state.
