IoT｜硬體｜Linkit 7697｜透過安裝於樹莓派之 OpenHAB，以 MQTT 控制 LED（門鎖） 燈
[事情準備]
安裝 Mosquitto 及設定
安裝 OpenHAB 及設定
安裝 OpenHAB、OpenHAB 2 for MQTT 擴充功能
安裝 OpenHAB for MQTT 擴充功能，首先安裝 binding，可以透過下表指令列出套件名稱
apt-cache search mqtt
安裝 openhab-addon-binding-mqtt
[OpenHAB]
sudo apt-get install openhab-addon-binding-mqtt
[OpenHAB2]
透過 Web UI 安裝 binding-mqtt1 - 1.9.0
[設定 OpenHAB、OpenHAB 2 MQTT]
配置 openHAB 使用 MQTT 服務
[OpenHAB]
sudo nano /etc/openhab/configurations/openhab.cfg
修改成以下內容
============

重新啟動服務，整體服務啟動時間約 2分鐘
[OpenHAB]
sudo systemctl restart openhab
設定值若有修改過，則須先載入設定值
----------------------------
sudo systemctl daemon-reload
[OpenHAB 2]
sudo systemctl restart openhab2
編輯 OpenHAB items 組態
[OpenHAB]
sudo nano /etc/openhab/configurations/items/door.items
[OpenHAB 2]
sudo nano /opt/openhab2/conf/items/door.items
內容如下
======
正式內容：
Switch bedroom "主臥室門控制開關#1 [%s]" <garagedoor> {mqtt=">[mybroker:sensors/linkit7697/myhome/bedroom/door1/switch:command:ON:1],>[mybroker:sensors/linkit7697/myhome/bedroom/door1/switch:command:OFF:0],<[mybroker:sensors/linkit7697/myhome/bedroom/door1/status:state:ON:1],<[mybroker:sensors/linkit7697/myhome/bedroom/door1/status:state:OFF:0]"}
測試內容：
Switch MQTT_Test "Testing..." {mqtt=">[mybroker:testing/mqtt/topic:command:ON:1],>[mybroker:testing/mqtt/topic:command:*:Switch ${itemName} was turned ${command}]"}
可透過訂閱主題查看測試訊息
mosquitto_sub -h yourmqttbrokerip -t testing/mqtt/topic
訊息如下：
Switch MQTT_Test was turned ON
Switch MQTT_Test was turned OFF
編輯 OpenHAB sitemap 組態
[OpenHAB]
sudo nano /etc/openhab/configurations/sitemaps/default.sitemap
[OpenHAB 2]
sudo nano /opt/openhab2/conf/sitemaps/default.sitemap
內容如下
------
sitemap default label="智慧門鎖控制系統" {
Frame label="Linkit-7697 門#1" {
Switch item=bedroom icon="garagedoor"
}
}
正常編輯 items 及 sitemap 不需重啟會立即更新，不過偶爾會遇到更新無效，這時候可以重新啟動服務試試，整體服務啟動時間約 2分鐘
重新啟動服務，整體服務啟動時間約 2分鐘
[OpenHAB]
