简介:本文详解如何通过小爱同学、米家设备与Home Assistant的协同,构建高自由度智能家居生态,覆盖硬件选型、协议对接、自动化配置及场景优化全流程。
本文以小爱同学为语音交互核心、米家设备为硬件基础、Home Assistant(以下简称HA)为中枢控制平台,通过四步搭建可扩展的智能家居生态。从硬件兼容性分析到自动化场景设计,结合代码示例与配置文件解析,提供从入门到进阶的完整方案,解决设备孤岛、协议不兼容等痛点,实现跨品牌设备联动与个性化场景定制。

# 使用Docker部署HA(推荐)docker run -d \--name homeassistant \--restart unless-stopped \-v /path/to/config:/config \-v /etc/localtime:/etc/localtime:ro \--network=host \ghcr.io/home-assistant/home-assistant:stable
# 在HA的HACS商店搜索"Xiaomi Miot Auto"并安装# 配置时需填写小米账号的Refresh Token(通过miot-auto-token工具获取)
# configuration.yaml 示例xiaomi_miot:devices:- id: '1234567890' # 设备SN号token: 'abcdef123456' # 设备tokenname: '客厅空调'
bluetooth_tracker集成配合HCI工具扫描zha集成自动发现设备
# 在HA的appdaemon目录下创建xiaomi_skill.pyimport appdaemon.plugins.hass.hassapi as hassclass XiaomiSkill(hass.Hass):def initialize(self):self.listen_state(self.handle_command, "input_text.xiaomi_command")def handle_command(self, entity, attribute, old, new, kwargs):if new == "打开客厅灯":self.call_service("light/turn_on", entity_id="light.living_room")
conversation组件处理多轮对话

recorder组件存储历史数据
# 示例:预测用电量import pandas as pdfrom sklearn.linear_model import LinearRegressiondata = pd.read_csv('/config/home-assistant_v2.db') # 实际需通过SQLite查询X = data[['temperature', 'humidity']]y = data['power_consumption']model = LinearRegression().fit(X, y)
