Xiaomi Mi Flora Plant Sensor MQTT Client/Daemon

A simple Linux python script to query arbitrary Mi Flora plant sensor devices and send the data to an MQTT server, e.g., the famous Eclipse Mosquitto or the embedded MQTT broker in Home Assistant.

The program can be executed in daemon mode to run continuously in the background.

Features

Support for Xiaomi Mi Flora sensors (tested with firmware v2.6.2, v2.6.4, v2.6.6)
Build on top of open-homeautomation/miflora
Highly configurable
Data publication via MQTT
JSON encoded
MQTT authentication support
Daemon mode
Reliable and inituitive

Installation

Shown for a modern Debian system:

git clone https://github.com/janwh/miflora-mqtt-daemon.git /opt/miflora-mqtt-daemon
cd /opt/miflora-mqtt-daemon

apt install python3 python3-pip bluetooth libbluetooth-dev libboost-python-dev libglib2.0-dev
pip3 install -r requirements.txt

Configuration

To match personal needs all operation details can be configured using the file config.ini.

Execution

A first test run is as easy as:

python3 mqtt-flora.py

With a correct configuration the result should look similar to the the screencap above.

The extensive output can be reduced to error messages:

python3 mqtt-flora.py > /dev/null

You probably want to execute the program continuously in the background. This can either be done by using the internal daemon or cron.

Detach from Shell

Send the daemon into the background with some simple command line foo:

   python3 /path/to/mqtt-flora.py &

Hint: Bring back to foreground with fg.

Screen Shell

Send the daemon into the background inside a screen shell:

   screen -S mqtt-flora -d -m python3 /path/to/mqtt-flora.py

Cron job

Add a new con job to e.g. /etc/cron.d/miflora to execute every 5 minutes

   */5 * * * * python3 /path/to/mqtt-flora.py > /dev/null

Integration

Data will be published to the MQTT broker topic "miflora/sensorname" (names configurable). An example:

{"light": 24, "moisture": 30, "temperature": 21.4, "conductivity": 1020, "battery": 100}

This data can be subscribed to and processed by other applications, like Home Assistant or openHAB.

Enjoy!
