HOME Assistant：使用nodemcu控制繼電器MQTT初步試水

05-03

關於智能家居這個問題，我們國內有許多的平台，但是他們都互相排斥，像米家和京東都有獨立的app控制。鑒於這個問題，我們可以通過樹莓派或者liux開發板或者舊手機來搭建HOME Assistant平台。

具體搭建方法可參照下列網站：通用 - Home Assistant 中文文檔

我用的是http://HASS.IO安裝的。

出現這種界面後。不要相信預計20分鐘。其實要半天時間。反正耐心等。

安裝完成後出現這個界面就算安裝成功了

安裝成功後：點擊http://hass.io>add-on

添加https://github.com/hassio-addons/repository源地址安裝

Mosquitto broker

Samba share

Homebridge

這幾個插件。並啟用它們。

接下來配置Homebridge

在我的電腦網路里發現HASSIO

打開\HASSIOconfighomebridge目錄找到config.json文件用Notepad++打開。在文件內添加

"default_visibility": "visible",

回到config文件夾找到configuration.yaml文件Notepad++打開配置MQTT和開關

mqtt: broker: 填入設備ip地址 username: 設置用戶名 password: 設置密碼switch: platform: mqtt name: "Sonoff_WoShi_3" state_topic: "home/Bed_room/3/stat" command_topic: "home/Bed_room/3" qos: 1 payload_on: "on" payload_off: "off" retain: true

然後點擊配置>通用>重啟服務

等待。如果無法重啟請留意home-assistant.log文件

拿出nodemcu

下載好Arduino-ide配置好開發環境

http://wechat.doit.am/package_esp8266com_index.json 或者

http://arduino.esp8266.com/stable/package_esp8266com_index.json

下載成功後在項目里添加zip庫文件

這是引腳圖

代碼是sonoff開關代碼。根據io口更改RELAY 代碼
