Hi we started looking at edgex again to see if its come any further for onvif, previously, the hkvision camera we had weas discovered with jakarta some noths ago, then we dropped the project, well its back now however with napa we get the following error. and tyhe camera is not found. We used tui-generator for a simple onvif and mqtt exporter, the following docker compose was created

simply put we want to utilize edge to discover onvif devices in the environment and export their feeds via mqtt to mainflux, any help is appreciated

[jiekechoo]

@outbackdingo Did you set the discovery network subnets before starting discovery action?

You could put the configuration to your compose file as shown below or use linux env settings, and try again:

            # Host Network Interface, IP, Subnet
            APPCUSTOM_DISCOVERYETHERNETINTERFACE: wlp1s0 # determine this setting for your machine
            APPCUSTOM_DISCOVERYSUBNETS: 192.168.93.0/24 # determine this setting for your machine
            APPCUSTOM_DISCOVERYMODE: multicast

or use the device-onvif-camera api: https://docs.edgexfoundry.org/3.1/microservices/device/services/device-onvif-camera/swagger/ to do that.

the auto-discovery documentation is here: https://docs.edgexfoundry.org/3.1/microservices/device/services/device-onvif-camera/supplementary-info/auto-discovery/

[outbackdingo]

Ive added the follwing to the docker-compose.yml, tore it all down and docker compose up -d and still same results.

environment:
  DEVICE_DISCOVERY_ENABLED: "true"
  DEVICE_DISCOVERY_INTERVAL: "1h"
  APPCUSTOM_DISCOVERYETHERNETINTERFACE: "eno1"
  APPCUSTOM_DISCOVERYMODE: "both" # netscan, multicast, or both

[jiekechoo]

Try to call the api manually?

[outbackdingo]

ok so... curl --data '192.168.1`0.1/24' -X PUT "http://localhost:8500/v1/kv/edgex/v3/device-onvif-camera/AppCustom/DiscoverySubnets"

resulted in...

[outbackdingo]

Okay and how/where do i set the secret name .. i dont recall having this error last time

level=WARN ts=2024-03-27T07:21:10.984079267Z app=device-onvif-camera source=credentials.go:105 msg="Device a34ac000-711d-11b2-806a-240f9bb602d6 is missing MAC Address, using default secret name"

[jiekechoo]

Yes, it works.

You should set the secret store, and bind the mac address to the secret name. see here: https://docs.edgexfoundry.org/3.1/microservices/device/services/device-onvif-camera/Walkthrough/deployment/ Map credentials to devices. section.

[outbackdingo]

ok i have 1 cameras working and can show rtsp stream url in the console all try / set appear to work, though im perplexed

StreamUri is showing

         }
      }
   }
]```

but that is the cameras interanl ip, so how do i export the cameera stream to mqtt to mainflux...

or is this not feasible? i would have thought streamUri was the embedded device running edgeX .....

i simply want to discover devices on the network and export their rtsp streams via mqtt to the cloud....

the docs seem vague on how to accomplish this? is it even feasible?

[jiekechoo]

but that is the cameras interanl ip, so how do i export the cameera stream to mqtt to mainflux...

Yes, it can be. Here is a simply guide you can refer:

• use a AutoEvent command for getting the StreamUri readings to the EdgeX MessageBus;
• setting a mqtt export to send the readings to the mqtt broker;
• Optional: transfer the mqtt message to mainflux..., it depends on your case's env.
