Frigate + MQTT + HA 推送摄像头----更新为PushDeer推视截图+视频

shenbo

更新一下：
HA的提醒在iPhone里不太好用，一点就消失了，还是推送消息比较灵活，一开始用了企业微信，但是比较麻烦，而且需要固定的公网IP，转用pushdeer，很好用，能一直看到消息点击图片后能跳转视频。

msg.text = "%23%23%20摄像机探测发现";
msg.pushkey = "xxx"; //Besnon
msg.desp = `**`+msg.payload.before.camera+`摄像头探测到有人**%0A%0A
**事件ID为`+msg.payload.before.id+`**%0A%0A
[![摄像机截图](http://xxx:5000/api/events/`+ msg.payload.before.id + `/snapshot.jpg)](http://xxx:5000/api/events/` + msg.payload.before.id +`/clip.mp4)%0A%0A
**注意安全！**`;
msg.method = "get";
return msg;

最近闲了没事，研究了一下frigate的mqtt topic，其中event这个topic做的真不错，可以用node red对payload检索后筛选出你要情况和截图推送，当然也可以接一堆自动化，看大家的需要。分享一下我的经验。
提醒效果：



大家可以细看一下： https://docs.frigate.video/integrations/mqtt/ 和 https://docs.frigate.video/integrations/api/
先贴一个frigate关于event这个payload的说明，其中type这个object对于截图的选择比较重要，分为new/update/end三个状态，官方的解释"Message published for each changed event. The first message is published when the tracked object is no longer marked as a false_positive. When Frigate finds a better snapshot of the tracked object or when a zone change occurs, it will publish a message with the same id. When the event ends, a final message is published with end_time set."

  "type": "update", // new, update, end
  "before": {

我是用Node Red的MQTTIN订阅frigate/events这个topic后，通过switch筛选需要的数据，最后用HA的notify.mobile服务推送带图片的消息

我遇到的坑主要是message的组合，大家可以参考以下内容



data部分的代码，关于message如何组合重点参考https://docs.frigate.video/integrations/api/

{
    "title": "摄像头探测到人员",
    "message": "{{payload.before.camera}}摄像头探测到有人 事件ID:{{payload.before.id}}",
    "data": {
        "ttl": 0,
        "priority": "high",
        "image": "http://192.168.1.14:5000/api/events/{{payload.before.id}}/snapshot.jpg"
    }
}

复制代码

frigate的object有很多，大家可以结合frigate的文档依据自己的需要调整。

你这个自定义不错，我是用的蓝图实现的推送，没有你这个灵活，参考下看看

直接用集成不是更方便？再导个自动化蓝图。

感觉推送截图这块有点不太好，因为并不能保证每次都能抓取到这个人的正脸，所以还是推送到企业微信让他抓取10秒内的画面比较好， 我个人感觉，不喜勿喷！
