Paso 2: Instale MQTT en su pi openhab
Esto es una continuación de mi post aquí
Utilice una conexión SSH para esta configuración. Hay otras formas de configurar MQTT con OpenHAB, pero este es compatible con ESP nodo MCU.
sudo apt-get update
sudo apt-get install build-essential python quilt devscripts python-setuptools python3
sudo apt-get install libssl-dev libwrap0-dev libc-ares-dev
sudo wget http://mosquitto.org/files/source/mosquitto-1.4.1.tar.gz
tar zxvf mosquitto-1.4.1.tar.gz
cd mosquitto-1.4.1
make all
sudo make install
sudo ldconfig
Ahora usted puede tratar de mosquitto:
Abrir dos ventanas de terminal. En el primer terminal que ejecute
mosquitto_sub -h 127.0.0.1 -t myTopic
En la segunda terminal ejecutar
mosquitto_pub -h 127.0.0.1 -t myTopic -m "My first message"
Activa a MQTT enlace con OpenHAb
sudo nano /opt/openhab/configurations/openhab.cfg
Buscar transporte MQTT y activar "dirección URL para el MQTT corredor" y "Id de usuario para autenticar con el corredor" por quitar la marquita en el principio de la línea.
