A simple Python script which provides a Bluetooth to MQTT gateway, easily extensible via custom workers.
See Wiki for more information.

• Highly extensible via custom workers
• Data publication via MQTT
• Configurable topic and payload
• MQTT authentication support
• Systemd service
• Reliable and intuitive
• Tested on Raspberry Pi Zero W

• EQ3 Bluetooth smart thermostat via python-eq3bt
• Xiaomi Mi Scale
• Linak Desk via linak_bt_desk
• MySensors
• Xiaomi Mi Flora plant sensor via miflora
• Xiaomi Aqara thermometer via mithermometer

These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.

• python3 >= 3.5
• pip3

On a modern Linux system, just a few steps are needed to get the gateway working. The following example shows the installation under Debian/Raspbian:

sudo apt-get install git python3 python3-pip bluetooth bluez
git clone https://github.com/zewelor/bt-mqtt-gateway.git
cd bt-mqtt-gateway
sudo pip3 install -r requirements.txt

All worker configuration is done in the file config.yaml. This file needs to be created first:

cp config.yaml.example config.yaml
vim config.yaml
./gateway.py

Attention: You need to add at least one worker to your configuration. Scan for available Bluetooth devices in your proximity with the command:

sudo hcitool lescan

A test run is as easy as:

sudo ./gateway.py

Debug output can be displayed using the -d argument:

sudo ./gateway.py -d

Continuous background execution can be done using the example Systemd service unit provided.

sudo cp bt-mqtt-gateway.service /etc/systemd/system/
sudo vim /etc/systemd/system/bt-mqtt-gateway.service
sudo systemctl daemon-reload
sudo systemctl start bt-mqtt-gateway
sudo systemctl status bt-mqtt-gateway
sudo systemctl enable bt-mqtt-gateway

Attention: You need to define the absolute path of gateway.py in bt-mqtt-gateway.service.
