MMM-KitchenTimer - Touch-friendly countdown timer

[Niggich]

@bwente Thank you for your answer. HA it’s a good idea, but how I tell HA I start the Timer on the mirror? I also have an iobroker. Maybe this helps…

@Niggich

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.

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…

@Niggich On the HA side you would listen for the timer topic.

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

@bwente Ok, thank you. So I don’t need to configure something at the MMM-MQTTbridge just in HA?

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

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.

@bwente Wow, you’re great. 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.

[Niggich]

@bwente I add the automation already and change it again but the echo still asking “for how log should be the timer”… I also try to fix it with ChatGPT but this was not working.

[bwente]

@Niggich looks like trigger.payload_json.remainingSeconds is empty or double quoted. Can you view just the payload and see?
