Requirements

• NodeJS (>=8.9.3) with NPM
• An MQTT broker and Cooper&Hunter smart HVAC device on the same network
• Docker (for building Hass.io addon)

Running addon locally

Create an ./data/options.json file inside the repo with persistent addon configuration.

docker run --rm -v "$PWD/data":/data cooper_hunter-hvac-mqtt-bridge

    {
        "hvac_host": "192.168.107.49",
        "mqtt": {
            "broker_url": "mqtt://192.168.1.100",
            "topic_prefix": "home/chhvac"
        }
    }

Running locally

Make sure you have NodeJS (>=8.9.3) installed and run the following (adjust the arguments to match your setup):

npm install
node index.js \
    --hvac-host="192.168.107.49" \
    --mqtt-broker-url="mqtt://localhost" \
    --mqtt-topic-prefix="home/chhvac"

Hass.io addon

The service can be used as a 3rd party addon for the Hass.io MQTT climate platform.

1. Install the addon
2. Customize addon options (HVAC host, MQTT broker URL, MQTT topic prefix)
3. Add the following to your configuration.yaml

climate:
  - platform: mqtt

    # Change to whatever you want
    name: CooperHunter HVAC

    # Change MQTT_TOPIC_PREFIX to what you've set in addon options
    current_temperature_topic: "home/chhvac/temperature_in/get"
    temperature_command_topic: "home/chhvac/temperature/set"
    temperature_state_topic: "home/chhvac/temperature/get"

    mode_state_topic: "MQTT_TOPIC_PREFIX/mode/get"
    mode_command_topic: "MQTT_TOPIC_PREFIX/mode/set"
    fan_mode_state_topic: "MQTT_TOPIC_PREFIX/fanspeed/get"
    fan_mode_command_topic: "MQTT_TOPIC_PREFIX/fanspeed/set"
    swing_mode_state_topic: "MQTT_TOPIC_PREFIX/swingvert/get"
    swing_mode_command_topic: "MQTT_TOPIC_PREFIX/swingvert/set"
    power_state_topic: "MQTT_TOPIC_PREFIX/power/get"
    power_command_topic: "MQTT_TOPIC_PREFIX/power/set"

    # Keep the following as is
    payload_off: 0
    payload_on: 1

      - "swingBottom"
      - "swingMidBottom"
      - "swingMid"
      - "swingMidTop"
      - "swingTop"
    fan_modes:
      - l0
      - l1

Configuring HVAC WiFi

1. Make sure your HVAC is running in AP mode. You can reset the WiFi config by pressing WIFI on the AC remote for 5s.
2. Connect with the AP wifi network (the SSID name should e.g. "SMART_083X"), the passwork should be 88888888.
