Track unique objects

Describe the bug Is there any way to track the same unique object. I meant how it is possible to avoid of being notified about the same unique object, like a parked car or a still person. Right now, I’m being bombarded by new messages about the same objects

I had the same issue. I am using Node-Red in Home Assistant to detect event updates, then there is a 5s trigger which is waiting for a snapshot with better score to arrive (I am not using the “end of event” report from Frigate, because some events take too long and I want to be notified earlier - before the end of event), so I am waiting 5sec for better score, if not, it will send a picture to my Telegram chat only once for each event (checks via rbe). I also send “inline keyboard” buttons with the picture so with single click on the button in the chat I can request a video clip, which is then sent as a new message to the chat.

If anyone is interested I can post a flow export.

btw I am also using 5FPS and max_disappeared set to 25 (5sec).
