[Support]: [MQTT] HA Notifications ghost events

[Morphy99]

Describe the problem you are having

I seem to occasionally get notifications for a Person object, however, the event doesn't exist and the snapshot doesn't show a box for an object anywhere. It also fails to download after a few minutes despite showing up in the notification preview on my mobile device.

This has been discussed often in past topics. /events is a raw MQTT topic, frigate has always published objects that were detected as true positives even if they did not qualify for an event to be created in the UI.

[NickM-27]

Also, the snapshot url doesn't show bounding boxes by default until the event is over. If you add ?bbox=1 to the end of the snapshot url it will show the bounding box

Sorry, I haven't searched the discussions as I've always just followed the docs. I will have a look for a better way, but if there is one, why aren't the docs referencing it?
I don't understand how the same filters for events aren't applied to MQTT when I'm using required_zones but anyway...

[hawkeye217]

From https://docs.frigate.video/integrations/mqtt#frigateevents:

Message published for each changed event. The first message is published when the tracked object is no longer marked as a false_positive.

As the docs state, every time something changes, it's published to this topic. Any kind of filtering must be done by the consumer.

The Home Assistant notifications guide give more:

It is generally recommended to trigger notifications based on the frigate/events mqtt topic. This provides the event_id needed to fetch thumbnails/snapshots/clips and other useful information to customize when and where you want to receive alerts. The data is published in the form of a change feed, which means you can reference the "previous state" of the object in the before section and the "current state" of the object in the after section.

If you have any other questions on how it works, feel free to ask, we're happy to help.

My bad, I'd forgotten that MQTT required_zones is only for snapshots. So if I wanted to filter notifications to zones I can use this?
{{ 'path_close' in trigger.payload_json['after']['entered_zones'] }}

Does this apply the object filters for area size which are defined in the zones in per camera config?

I have notes to say the 'payload: new' messages don't include entered zones however which would mean a slight delay and having to use 'payload: update' messages?

Basically, I just want the fastest notifications for events with the same filters I have set to avoid false positives.

I've come across Nick's guide at using the new review notifications which I'm going to give a go. One question about that, does the notification trigger at the end of the event?

Yep, that looks right.

The review topic is probably the better source for notifications in 0.14. As with the events topic, you'll see end as the message type when the review time period ends.
