Commentary

The first time an event occurs, the result of the first automatic update will be sent. After that, an event will be generated every time the device down status of the unit changes.

If the update fails from the beginning, an event will occur with False immediately after the first automatic update, and then when the device is officially deemed to be down, an event will occur with False again.
