192.168.1.17 being your MQTT broker IP address.

Once the command launched you should see MQTT payloads appearing on the broker. To visualize these data you have to use an MQTT client tool.

Example payload received:

{"name":"F35285","id":"F3:52:85","rssi":-82,"brand":"BlueMaestro","model":"TempoDisc","model_id":"BM_V23","tempc":24.1,"tempf":75.38,"hum":104.7,"dp":24.8,"volt":2.56}

# Configuration record

Once you have entered your credentials and parameters they are saved into a configuration file theengsgw.conf into your user directory and you can simply launch the gateway by using:

python -m TheengsGateway

# MQTTtoMQTT decoding

Messages sent to the subscribe topic can be used for decoding BLE data and will be published to the publish topic. This allows for offloading the decode operation from other devices, such as an ESP32, to enhance performance.

The data sent to the topic is expected to be formatted in JSON and MUST have at least an "id" entry.

Example message:

{
  "id":"54:94:5E:9F:64:C4",
  "mac_type":1,
  "manufacturerdata":"4c0010060319247bbc68",
  "rssi":-74,
  "txpower":12
}

If possible, the data will be decoded and published.

# Home Assistant auto discovery

If enabled (default), decoded devices will publish their configuration to Home Assistant to be discovered.

  • This can be enabled/disabled with the -D or --discovery command line argument with a value of 1 (enable) or 0 (disable).
  • The discovery topic can be set with the -Dt or --discovery_topic command line argument.
  • The discovery name can be set wit the -Dn or --discovery_name command line argument.
  • Devices can be filtered from discovery with the -Df or --discovery_filter argument which takes a list of device "model_id" to be filtered.

The IBEACON, GAEN and MS-CDP devices are already filtered as their addresses (id's) change over time resulting in multiple discoveries.
