"Multiple cameras configured" error, can't figure out where they are!

[jlg89]

I'm seeing this in my log, and camera MQTT events aren't working:

Each camera is defined exactly once in the dafangMqtt section and in the Camera-ffmpeg sections of config.json. I've tried deleting everything in the "accessories" directory, and there are no duplicates in the "persist" directory. Where else do I need to look?

Please share your config.

The code that generates those warnings only looks at the config, not the persist folders or anything, so something must be configured wrong.

[Sunoo]

Not familiar with that plugin_map attribute in each of these config sections, is this HOOBS or something?

[jlg89]

Yes.

HOOBS 3.3.3 Homebridge 1.3.1 Node 14.15.1

Raspberry Pi 3 Model B Plus Rev 1.3 Raspbian "Buster" 10, kernel 5.4.72-v7+

[Sunoo]

Okay, I haven’t done testing with HOOBS quite yet, but I have a HOOBS device being delivered tomorrow for testing purposes. Once that comes in, I’ll see if I can recreate the issue there, maybe they do something different than Homebridge does.

[mkellsy]

This almost looks like there's 2 instances of HOOBS running. I've come across this when testing Homebridge 1.3.x.

Right run ps -a and see if there are multiple node processes.

I see this happen when HOOBS is ran by the system via the hoobs.service file and another via the terminal.

I hope this helps.

[jlg89]

"ps ax|grep hoobs" shows two hoobs processes running, but I have no idea why that would be, or whether or not that's expected behavior. I haven't done anything to startup a second process. There's only one hoobs.service file in /etc/systemd/system.

[mkellsy]

If you haven't try rebooting. That might clear it up.

There may be 2 hoobs processes one for the hub and one for the bridge (I think, been working on a new version)

Is there a homebridge.service file in /etc/systems/system? Also if you stop the hoobs process. Is there still a hoobs or node in your process list?

[jlg89]

If I "Stop Service" using the HOOBS webUI, one of the hoobs processes disappears. So it would seem that one of the processes is the "master" that runs the webUI, and the other is the one that handles all the accessories.

There is a /etc/systemd/system/hoobs.service file:

[Unit]
Description=HOOBS
After=network-online.target

[Service]
Type=simple
User=hoobs
ExecStart=/usr/local/bin/hoobs
Restart=on-failure
RestartSec=3
KillMode=process

[Install]
WantedBy=multi-user.target

[mkellsy]

Yes /usr/local/bin/hoobs starts an API and the UI. Then it starts Homebridge. The API is the control plane.

To control the services without the UI you have to use ssh from another computer.

ssh hoobs@hoobs.local

The password is hoobsadmin.

[mkellsy]

Let's see what Sunoo finds. I am starting to think it's a config issue.

[Sunoo]

My goal is to look into this issue and attempt to recreate it this weekend. Pretty crazy time for me at the moment, unfortunately.

[jlg89]

No pressure, I really appreciate the very impressive work you've put into all of your plugins.

FWIW, I'm not sure exactly when this particular issue started occurring, but it could have something to do with Homebridge 1.3.x and/or HOOBS 3.3.x.

[Sunoo]

I did some testing under Homebridge 1.3.0, though maybe not as thoroughly as I could have, and it worked. I just had a lot of plugins to try to make sure we’re broken by that version’s changes. I’ll play around some more when I have a second, and see if I can make it break under Homebridge, and if not I’ll try under HOOBS once UPS gets that to me.

[jlg89]

If I can do anything to help, let me know. I'm good in the guts of UNIX.

[Sunoo]

I’ll keep that in mind. I’m just a bit stumped as to what is causing this, since your config looks like it should be valid. The only way I could see the error happening would be if somehow the config is duplicated by Homebridge/HOOBS. Hopefully once I have a chance to load your config into a HOOBS setup, I’ll be able to work out exactly what’s happening.

[jlg89]

I disabled the error flagging in index.js for camera.name and camera.dafang_topic...

            if (this.cameras.find(camera => camera.name === camera.name)) {
                this.log.warn('WARNING: Multiple cameras named "' + camera.name + '" configured. Only the first loaded will function.');
                error = false;
            }
            if (this.cameras.find(camera => camera.dafang_topic === camera.dafang_topic)) {
                this.log.warn('WARNING: Multiple cameras with topic "' + camera.dafang_topic + '" configured. Only the first loaded will function.');
                error = false;
            }

...and it looks like all the MQTT traffic is doing its thing. Camera controls work, motion detect events are sending images, etc. It's not making it into HomeKit for some reason, though.

Sounds like you maybe have two separate issues going on then.

[jlg89]

I noticed I didn't have an "mqtt:" section in my camera-ffmpeg config. So, the camera I'm testing now looks like this:

    {
        "name": "StudyCam",
        "manufacturer": "Wyze",
        "model": "Wyzecam Pan",
        "motion": true,
        "motionTimeout": 0,
        "debug": true,
        "videoConfig": {
            "source": "-i rtsp://192.168.77.12:8554/unicast",
            "stillImageSource": "-i rtsp://192.168.77.12:8554/unicast -vframes 1 -r 1",
            "vcodec": "copy",
            "audio": true,
            "debug": true
        },
        "mqtt": {
            "motionTopic": "yonder-alerts/studycam"
        }
    }

I'm still not getting motion detect notifications in HomeKit; do I need to use a different motionTopic setting for a Dafang-Hacks camera?

[jlg89]

Now we got notifications in HomeKit. Sheez.

    {
        "name": "StudyCam",
        "manufacturer": "Wyze",
        "model": "Wyzecam Pan",
        "motion": true,
        "motionTimeout": 0,
        "videoConfig": {
            "source": "-i rtsp://192.168.77.12:8554/unicast",
            "stillImageSource": "-i rtsp://192.168.77.12:8554/unicast -vframes 1 -r 1",
            "vcodec": "copy",
            "audio": true,
            "debug": true
        },
        "mqtt": {
            "motionTopic": "yonder-alerts/studycam/motion",
            "motionMessage": "ON",
            "motionResetTopic": "yonder-alerts/studycam/motion",
            "motionResetMessage": "OFF"
        }
    }

Sorry about that, I missed that when I was looking at your config before. Yea, I completely reworked MQTT support in Camera FFmpeg a few versions ago to better support more devices natively without relying on these sorts of helper plugins. Glad you got that resolved.

I still need to work out why this plugin is barfing on your config though.

[Sunoo]

Sorry for the slow response, it’s been a bit crazy for me.

I believe I’ve found the cause of this issue, just need to do a bit more testing, and I’ll get the new version published. Should be this weekend.

[jlg89]

Dude, I have customers who have been waiting on a software update for 5+ months! Most of that holdup has been regulatory red tape, but still, I'm getting paid to do it. You don't have to apologize for slow response on free software, especially something as ultra-functional as your stuff. Take your time, live your life. Praying for less craziness. :)

[Sunoo]

Sorry for the delay, moving took a lot out of me. v2.3.1 should fix this issue.

[jlg89]

Congrats on the move. I hate moving.

Looks like you fixed the issue. No more errors, and it all seems to be happy now.

[Sunoo]

Fantastic! It turned out to be an incredibly stupid mistake (aren’t they always?) that I didn’t catch because I only have one WyzeCam.
