@radioman Hi. You made one mistake in the configuration for your page devices. You set OnOff to true. If it’s set to true you can send different notifications for on and off. So you have to set it to false for this two devices. Your config looks then like this:

{
    module: 'MMM-AlexaControl',
    position: 'bottom_left',
    config:{
        image: false,
        pm2ProcessName: "mm",
        refresh: true,
        restart: true,
        reboot: false,
        monitorToggle: true,
        vcgencmd: 'vcgencmd',
        deviceName: "Spiegel",
        startPort: 12000,
        notifications: [
                            {
                                name: 'Radar',
                                port: 11101,
                                OnOff: true,
                                notification: [["SHOW_RADAR", null],["HIDE_RADAR", null]]
                            },
                            {
                                name: 'Seite eins',
                                port: 11102,
                                OnOff: false,
                                notification: ["PAGE_CHANGED", 0]
                            },
                            {
                                name: 'Seite zwei',
                                port: 11103,
                                OnOff: false,
                                notification: ["PAGE_CHANGED", 1]
                            }
                        ]
    }
},

Instead of this you could also use the pages option and set it to the number of pages you have. You can then change the names in the Alexa app.
