DIY 小米智能家居功能擴充（爆水管關水掣例子）
淘寶買個 [紅外線（IR）無線射頻（RF）轉換器]，（小米萬能遙控）除控制红外缐設備外，亦可擴大到控制其它無缐射頻组件。這裏加配上一個無線遙控的90度水掣開關機械手，小米的水浸警報器在水浸時，除了在網關發出警報聲及信息推送到手機外，更可以指示機械手搖90度關上水掣！片中的水開關掣還未装上水管，只装上機械手，用作反應水浸警報器作效果试驗。

DIY 的小愛同學人工智能
家中来了個肥大的小米空氣過濾，實無空間容下小愛，只有賣左佢比個有錢嘅大户人家......有點傷感！不過我呢個有錢啲朋友買小爱之前，問她可不可以控制芭蕉扇，我說她可以控制這部一萬mA電量的大風散熱扇，他才買！不過相信佢回家重置小爱後會後悔，因為其實小爱都幾蠢！ *睇片要開聲才知道做什麼
