智能家居的话，如果只能手动控制会觉得不太智能，如果能用说的或者自动的话体验可能会更好一些。
智能家居其实就是为了给生活添加一些便利，懒人推送科技发展是没错的。
对于个人而言接入智能家居无非有以下几个原因：
1、动动手动动嘴不动腿就是懒恨不能意念控制
2、开关对小朋友不友好，个头不够摸不到开关
3、全屋联动回家模式离家模式等等
基于以上几个原因
通过尝试。实现了语音控制 HA 设备的基本功能。
主要思路如图：
开始想着增加机械开关手动去操作，后来想了以下都语音控制了还要物理开关干嘛呢。
小朋友和老人，直接语音控制开关设备。就很舒服呢。
对于红外设备，还没研究透彻怎么去获取遥控器的红外编码，然后发射出来。这样就可以实现更多的功能。
可以语音控制空调、电视等红外设备。
[智能家居]MQTT 控制 HomeAssistant 设备

(出处: 物联网开发者社区-安信可论坛)
这里主要还是用到了 HomeAssistant 的自动化功能，这种设置不需要对 HomeAssistant 有很深的了解，简单配置即可。
对于小白用户体验更好一些，上手就用。对于大佬的话，可以延伸出更多的功能。
下面介绍一下主要功能模块
一、离线语音模组系列
VC 系列模组是我司开发的一款 AI 离线语音识别的产品，主芯片是云知声推出的离线语音识别芯片锋鸟 M(US516P6)，具有高可靠性，通用性强的特点。在语音识别技术上实现了高可靠的唤醒识别率、更远距离的唤醒、更低误唤醒率、更强的抗噪音能力、更快的响应识别时间，免联网的纯离线识别。
VC 系列模组采用了 32bit RISC 架构内核，并加入了专门针对信号处理和语音识别所需要的 DSP 指令集，支持浮点运算的 FPU 运算单元，以及 FFT 加速器。支持最高 150 条本地指令离线识别，支持 RTOS 轻量级系统，以及简单友好的客制化工具。
VC 系列模组具有丰富的外围接口，包括 UART/I2C/PWM/SPI，以及简单友好的二次开发工具,方便客户实现单模组的语音控制应用场景方案。
VC-02 模组
扬声器功率尽量不要太大，如果用 M61-32S 供电扬声器功率过高会导致掉电。
扬声器：

串口烧录工具
定制语音
安信可语音开放平台：http://voice.ai-thinker.com/
在安信可语音开放平台创建产品，选择 VC 系列模组。
然后修改唤醒词
设置 Pin 引脚功能
波特率设置 115200，引脚 B6 设置为 UART1_RX 引脚 B7 设置为 UART1_TX,用来发送接收数据。注意不要配置多个 UART1，否则不生效。
添加语音指令
然后添加控制详情
这里主要用到的就是串口数据，这里发送指令 第一位是指令开头默认 A1，第二位定义的是设备位置，第三位定义的是设备类型，第四位定义的是开关状态，第五位结束位默认 FF。根据自己的需要设置解析即可。
还有免唤醒命令，不用唤醒词直接就可以用，比如开灯、关灯等等。
免唤醒命令词最多 10 个选择自己需要的添加，添多了也是默认取前 10 条。
二、Ai-M61-32S Wi-Fi 模组
Ai-M61 系列模组（下称模组）是由深圳市安信可科技有限公司开发的 Wi-Fi6 & 蓝牙双模模组，搭载 BL618 芯片作为处理器，支持 Wi-Fi 802.11b/g/n/ax 协议和 BLE 5.3 协议。BL618 芯片内置低功耗的 32 位 RISC-V CPU，最高主频可达 320M. 丰富的外围接口，包括 DVP、MJPEG、Dispaly、Audio Codec、USB2.0、SDU、以太网(EMAC)、SD/MMC(SDH)、SPI、UART、I2C、I2S、PWM、GPDAC、GPADC、ACOMP 和 GPIO 等。可广泛应用于音视频多媒体、物联网(IoT)、移动设备、可穿戴电子设备、智能家居等领域。
