    Hi all,

    just re-installed my Magic Mirror and I wanted to use my sensor for monitoring room temperature again.

    I installed the MMM-temp-ds18b20 module. All went fine during installation, but when I edited my config and started my Magic mirror (via PM2 command), the screen just stays black (but I can see my mouse cursor). So probably, something went wrong by loading this module. Removing the module from the config and everything is okay.

    Additional information: By using the command (ls /sys/bus/w1/devices) I can find my sensor, which is correctly attached to my Pi3B+ and I can read the temperature. But I realized that my sensor ID does not start with 28-XXX but rather 10-XXX.

    Therefore, I edited my config like this:

    modules: [
    {
    module: ‘MMM-temp-ds18b20’,
    position: ‘top_right’,
    header: ‘Temperature sensors’,
    config: {
    refreshInterval: 10, // in seconds
    displayMode: ‘x-stack’,
    sensors:[
    {
    id: “10-xxxxxxxxxx”,
    label: “inside”
    }
    ]
    }
    },
    ]

    So maybe you can help with the issue that the screen stays black.

    Thank you very much!

    Best regards!
