While I enjoy tinkering with Home a**istant to make my smart devices work, I ensure all of them are manageable locally. While axing most cloud-dependent services, the only thing I miss is voice control. Recently, I hooked up a $13 ATOM Echo speaker to Home a**istant, and it has been a game-changer for my smart home. Tumbling down the rabbit hole, I managed to build a private voice a**istant that works locally.
