Smart Motion events not arriving with Dahua IP cam

Hi Ronnie, thanks for your work on the integration!

I’m having some issues receiving SMD events from my Dahua cameras.

I’m using a Dahua IPC-HDW5442TP-ZE-2712, firmware: 2.820.15OG001.0.R,build:2021-05-25. Integration version 0.9.38. HA 2022.2.9.

Enabled entities in HA:

When I query a camera’s API directly, I see smart motion events:

$ curl -s --digest -u admin:$DAHUA_PASSWORD \
  "http://10.0.60.2/cgi-bin/configManager.cgi?action=getConfig&name=SmartMotionDetect"
table.SmartMotionDetect[0].Enable=true
table.SmartMotionDetect[0].ObjectTypes.Human=true
table.SmartMotionDetect[0].ObjectTypes.Vehicle=true
table.SmartMotionDetect[0].Sensitivity=High

$ curl -s --digest -u admin:$DAHUA_PASSWORD \
  "http://10.0.60.2/cgi-bin/eventManager.cgi?action=attach&codes=[All]&heartbeat=5"

}

Code=SmartMotionVehicle;action=Start;index=0;data={
   "RegionName" : [ "Region1" ],
   "WindowId" : [ 0 ],
   "object" : [
      {
         "Rect" : [ 5384, 4096, 6352, 4904 ],
         "VehicleID" : 18028
      }
   ]
}

Using the event listener in HA, I only get generic VideoMotion events (instead of code SmartMotionVehicle, see DAHUA_HTTP_API_V2.76 page 83):

{
    "event_type": "dahua_event_received",
    "data": {
        "name": "Front yard",
        "Code": "VideoMotion",
        "action": "Start",
        "index": "0",
        "data": {
            "Id": [
                0
            ],
            "RegionName": [
                "Region1"
            ],
            "SmartMotionEnable": true
        },
        "DeviceName": "Front yard"
    },
    "origin": "LOCAL",
    "time_fired": "2022-02-19T15:56:34.971665+00:00",
    "context": {
        "id": "41827b2271a562574581382fe319943c",
        "parent_id": null,
        "user_id": null
    }
}

Debug logs:

2022-02-19 16:56:34 DEBUG (MainThread) [custom_components.dahua] Cam Data received from channel 0: {'name': 'Front yard', 'Code': 'VideoMotion', 'action': 'Start', 'index': '0', 'data': {'Id': [0], 'RegionName': ['Region1'], 'SmartMotionEnable': True}, 'DeviceName': 'Front yard'}
2022-02-19 16:56:37 DEBUG (MainThread) [custom_components.dahua] Finished fetching dahua data in 0.068 seconds (success: True)
2022-02-19 16:57:20 DEBUG (MainThread) [custom_components.dahua] Cam Data received from channel 0: {'name': 'Front yard', 'Code': 'VideoMotion', 'action': 'Stop', 'index': '0', 'data': {'Id': [0], 'RegionName': ['Region1'], 'SmartMotionEnable': True}, 'DeviceName': 'Front yard'}

So the binary_sensor.front_yard_smart_motion_human and binary_sensor.front_yard_smart_motion_vehicle sensors remain quiet, while the generic binary_sensor.front_yard_motion_alarm_2 does respond to generic motion events.

BTW, you can try this locally… Edit this file - https://github.com/rroller/dahua/blob/main/custom_components/dahua/client.py#L608

Change codes = ",".join(events) to codes = "All"

I might have an idea of what’s going on, maybe, but it’s hard to confirm. It’s possible that the event parsing isn’t that great and if more than 1 event arrives in a single message, only the first one is processed. I have some better event handling code I’ve just written that I’ve tested and verified works when it receives more than 1 event. I’ll let you know when I release the code… should be today.
