My Echo know I want to start a Timer but it’s asking for how long.

Great, now that you’ve confirmed MQTT is working, the next step is to add the Home Assistant automation.

alias: MagicMirror kitchen timer started
triggers:
  - trigger: mqtt
    topic: magicmirror/kitchen-timer/started

actions:
  - action: media_player.play_media
    target:
      entity_id: media_player.kitchen_echo
    data:
      media_content_type: custom
      media_content_id: >-
        set a timer for
        {{ trigger.payload_json.remainingSeconds | int }}
        seconds

I think that will work. I don’t know if it needs to be escaped or not.

Something like this for your MMM-MQTTbridge config on your mirror.

{
  module: "MMM-MQTTbridge",
  disabled: false,
  config: {
    mqttServer: "mqtt://USERNAME:PASSWORD@192.168.1.10:1883",
    stringifyPayload: true,

    mqttConfig: {
      // This example only sends MagicMirror events to MQTT.
      listenMqtt: false,
      interval: 300000,
    },

    notiConfig: {
      listenNoti: true,
      ignoreNotiId: ["CLOCK_MINUTE", "CLOCK_SECOND", "NEWS_FEED"],
      ignoreNotiSender: ["system"],
      qos: 0,
    },
  },
},

then edit

~/MagicMirror/modules/MMM-MQTTbridge/dict/notiDictionary.js

var notiHook = [
  {
    notiId: "KITCHEN_TIMER_STARTED",
    notiPayload: [
      {
        notiMqttCmd: ["Kitchen timer started"],
      },
    ],
  },
];

var notiMqttCommands = [
  {
    commandId: "Kitchen timer started",
    mqttTopic: "magicmirror/kitchen-timer/started",
    stringifyPayload: true,
    retain: false,
    qos: 0,
  },
];

module.exports = { notiHook, notiMqttCommands };

after restarting your mirror you should be able to listen for the topic: magicmirror/kitchen-timer/started in Home Assistant developer tools.

edit: I try the whole afternoon, but I don’t know how to do. I also try it with MMM-HomeAssistant.

alias: Start Echo timer from MagicMirror
triggers:
  - trigger: mqtt
    topic: magicmirror/kitchen-timer/started

actions:
  - action: media_player.play_media
    target:
      entity_id: media_player.kitchen_echo
    data:
      media_content_type: custom
      media_content_id: >-
        set a timer for
        {{ trigger.payload_json.remainingSeconds | int }}
        seconds

Ok, I try to configure MMM-MQTTbridge to connect the mirror to my HA. I think the connection from Mirror to HA is working but I don’t know how to configure the module to Send Notifications to my HA. Sorry…

Yes. Since you use Home Assistant, MagicMirror can publish an MQTT message when the timer starts, and HA can start a matching Alexa timer on the Echo paired with the Wall Clock.

The catch is they are separate timers, not truly synced. Starting and canceling can be synced, but pausing the MagicMirror timer will not pause Alexa.

One option is to pair your Screen with the Echo over Bluetooth. That would give you the alarm sound through the Echo, but it wouldn’t activate the timer indicator on the Echo Wall Clock.

Another possibility may be installing alexa-remote on the Mirror or use HA. The module could notify it when a timer starts, and it could then ask the Echo to set the corresponding timer. That should also activate the Wall Clock. maybe?
