【居家辦公】午餐吃什麼的自動化通知

透過 Home Assistant 打造自動午餐提醒功能，減少居家辦公時每天花在「想午餐」上的時間。

一個會自動通知你午餐要吃什麼的小功能。

自從開始居家工作之後，更注重於時間管理，準時的上下班、午餐時間，固定的儀式感，才不會模糊掉工作與生活的界線。

然而除了自己的儀式感之外，也在自家的 HomeAssistant 上簡單的拉了一個自動提醒午餐的功能，減少自己每天花在「想午餐」這件事情上的時間。

發想

每次午餐都不知道吃什麼，都要花時間想，原先只是想說有個簡單的工具可以每次亂數抽一下午餐要吃什麼，上網找了幾個工具，可以使用沒錯，但是好像還是不那麼理想。

後來就想到，不就是簡單的亂數，乾脆直接在 HA 拉一個功能，還可以自動化幾個規則：

  • 固定 12 點鐘觸發
  • 判斷是否為上班日
  • 發送抽午餐通知，順便提醒午餐時間到了

判斷是否為上班日：這是我另一個根據行事曆唯依據的判斷邏輯，簡單的可以用是否為平日判斷即可

設定流程

在 packages 資料夾底下，創建一個 random_lunkch.yaml

input_select:
  my_lunch:
    name: 午餐
    icon: mdi:food
    options:
      - 鍋貼

input_text:
  new_lunch:
    name: 新增午餐文字
    icon: mdi:food
  today_lunch:
    name: 今日午餐文字
  lunch_options_temp:
    name: 午餐選項暫存

input_button:
  new_lunch:
    name: 新增午餐
    icon: mdi:playlist-plus
  remove_lunch:
    name: 移除午餐
    icon: mdi:playlist-minus
  get_lunch:
    name: 抽午餐
    icon: mdi:bullseye-arrow

然後在 NodeRed 上拉個流程

這是第一次完整在 HA 上弄不是串接硬體裝置的功能，還蠻有趣的，透過這個功能每天省下的時間，可以拿去做更多想做的事情～
