Is there a feature in Home Assistant that allows for recording a timeline of custom events as their own entity? I’m looking for a way to log user-defined events—either as one-time occurrences or ongoing activities—to add meaningful context to existing data. Something that can be overlaid when viewing charts from other entities.
You can raise custom events as script, automation, or dashboard actions and consume them with Event triggers in automations or trigger-based template sensors.
