Error when using the plugin / Cannot read ATV activity status

[saschafiedler]

I have successfully installed and configured the plugin according to the instructions, but I get the following error message when using it:

[21/10/2022, 21:47:16] [homebridge-cmd-television] This plugin threw an error from the characteristic 'Active Identifier': Unhandled error thrown inside write handler for characteristic: The "file" argument must be of type string. Received undefined. See https://homebridge.io/w/JtMGR for more info.

Is the problem known and where is my error?

Do I understand the sample configuration file correctly, that I swap the MAC address with the one of my Apple TV?

[NorthernMan54]

This is indicating that your config file is incorrect, can you share it ?

[saschafiedler]

Sure:

{
    "bridge": {
        "name": "Homebridge",
        "username": "xxx",
        "port": xxx,
        "pin": "xxx",
        "advertiser": "avahi"
    },
    "accessories": [
        {...}
        {
            "accessory": "cmd-television",
            "name": "Apple TV",
            "oncmd": "atvremote --id xx:xx:xx:xx:xx:xx (Wifi mac address) --airplay-credentials `cat ~/.homebridge/atv_airplay.cred` --companion-credentials `cat ~/.homebridge/atv_companion.cred` turn_on",
            "offcmd": "atvremote --id xx:xx:xx:xx:xx:xx (Wifi mac address) --airplay-credentials `cat ~/.homebridge/atv_airplay.cred` --companion-credentials `cat ~/.homebridge/atv_companion.cred` turn_off",

    ],

    ]
}

Do you have this text in your config section ? (Wifi mac address)

Also I presume your running this on a Raspberry PI, and what version of homebridge are you running ?

[saschafiedler]

Do you have this text in your config section ? (Wifi mac address)

No. Just to clarify, that I used the in my case correct MAC address.

Also I presume you’re running this on a Raspberry PI, and what version of homebridge are you running ?

Yes, I do. Raspi 4 with a current version of Raspbian. I’m running 1.5.0 of Homebridge.

I have been trying a couple of different things in an attempt to recreate your issue, but have not been successful.

My only other thought, is re-install the plugin again

Did you use the command sudo npm i -g https://github.com/NorthernMan54/homebridge-cmd-television ?
