A device is represented in Home Assistant via one or more entities. For example, a battery-powered temperature and a humidity sensor might expose entities for temperature, humidity and battery level. Entity device info is only read if the entity is loaded via a [config entry](config_entries_index.md). + Each entity is able to define a device via the `device_info` property. This property is read when an entity is added to Home Assistant via a config entry. A device will be be matched up with an existing device via supplied identifiers and connections, like serial numbers or MAC addresses. ```python
