Events

Every event the devices emit, newest first by when it happened. Lateness is the gap to when we heard.

Exact match, e.g. presence.detected
Lower number = more severe
Happened (event_time · server filter)
Received (ingest_time · narrows this page)

The API filters only on when an event happened. This second range filters the page you are looking at by when we accepted it — the two are hours apart after a backlog flush.
