Installation

Build using java 17 or download prebuilt libraries.

1. Create a config.json for your aircon/MQTT requirements.

To integrate this library into your project, add the following dependencies to your pom.xml file:

  {

"globalSettings" :{"AirconQueryinterval": 30000
                    },


"mqttSettings": {"hostname": "192.168.0.101",
                "username": "openhab",
                "password":"test123"},


"aircon": [{"hostname":"192.168.0.12",
            "port": "51443",
            "deviceID": "e8165615c7d6",
            "operatorID": "openhab"
            }
]


}

2. Run the .jar file

java -jar mhi.jar

3. Topic paths:

The topic structure is as follows: aircon/{airconID}/ReadOnly/{dataName} for state reading aircon/{airconID}/ReadWrite/{dataName} for command writing

Anything posted in ReadWrite is passed to aircon, the response from aircon is then loaded into ReadOnly topics.

Usage:

The bridge is based on an aircon java class that can be found here for standalone development/inlcusion within other topics for people.
