The Reolink integration exposes a number of entities for each camera. For triggering a notification on motion detection, I'll be interested in the [binary sensor](https://www.home-assistant.io/integrations/binary_sensor/) entities named like `binary_sensor.$location_$type` (like `binary_sensor.backyard_person` and `binary_sensor.driveway_vehicle`), the state of which will transition from `off` to `on` when the selected motion type is detected.

That last line is taking advantage of Jinja templating and [trigger variables](https://www.home-assistant.io/docs/automation/templating/#state) so that the resulting notification displays the friendly name of whichever `binary_sensor` triggered the automation run. This way, I'll see something like "Backyard Person" instead of the entity ID listed earlier.
