HomeAssistant搭建,并将ESP8266通过MQTT接入
HTML 2024-03-24 15:49 647
之前将ESP8266接入巴法云,使用一段时间后,发现不够稳定,干脆直接在内网搭建一个HomeAssistant实现灯的控制.这里使用docker搭建:
homeassistat(Home Assistant 2021.12.8):
version: '3' services: homeassistant: privileged: true image: 'homeassistant/home-assistant:stable' container_name: 'homeassistant' environment: - TZ=Asia/Shanghai network_mode: host volumes: - /home/file/docker/homeassistant/config:/config restart: unless-stopped
启动完成后访问服务器8123端口完成初始化.
还需要安装一个mqtt服务端,这里同样使用docker搭建
mosquitto:
version: "3.0" services: mosquitto: container_name: 'mosquitto' image: 'eclipse-mosquitto:2.0.18' ports: - 1883:1883 - 9001:9001 volumes: - /home/file/docker/mosquitto/config:/mosquitto/config - /home/file/docker/mosquitto/data:/mosquitto/data - /home/file/docker/mosquitto/log:/mosquitto/log
mosquitto.conf
persistence true #persistence_location /mosquitto/data #log_dest file /mosquitto/log/mosquitto.log listener 9001 port 1883 allow_anonymous true
启动mqtt服务器,然后来到HomeAssistant管理页面,
左侧配置-设备与服务,右下角添加集成,找到MQTT,输入刚刚搭建的mqtt服务器.
烧录开发板,跟前一篇文章的巴法云代码一样,这里再贴一下,设备接线参考 ESP8266通过巴法云接入米家
我这边使用的WiFiManager版本为0.16.0,发现使用最新版2.0.17有无法连接MQTT服务器的问题

烧录完成后,现在为HomeAssistant添加该设备
在homeassistant的configuration.yaml中最后添加一行
light: !include light01.yaml
随后在configuration.yaml同级目录添加light01.yaml,内容为
- platform: mqtt name: "卧室灯" state_topic: "light001/set" command_topic: "light001" payload_on: "on" payload_off: "off" optimistic: false qos: 0 retain: true
完成后重启homeassistant即可
连接HomeKit
配置-设备与服务中添加HomeKit,然后开放端口
