Xiaomi mi flora

Script to read Xiaomi Flora values and publish it via MQTT to be used in Openhab or other home automation

It will scan for all Xiaomi miflora devices and publish the values to the MQTT server.

Paho (mqtt) and gatt libraries are required.

to install :

sudo apt-get install python-pip
pip install paho-mqtt
pip install gattlib

In case that gattlib can't be installed, make sure that you also apt-get it's dependencies :

pkg-config
libboost-python-dev
libboost-thread-dev
libbluetooth-dev >= 4.101
libglib2.0-dev
python-dev

this requires Bluez 5.37 or higher to be installed as well

To run this as non-root run the following

sudo setcap cap_net_raw+eip $(eval readlink -f `which python`)

to run this in an automated way every 30 min add to the crontab the script:

$ crontab -e

add the line:

*/30 * * * * /usr/bin/python /home/ubuntu/miflower.py >/dev/null 2>&1

(replace the last part with your file name & path)

Based on the script created by emeryth https://wiki.hackerspace.pl/projects:xiaomi-flora

Sample miflora.items config:

1. replace broker with whatever it is called in your mqtt.cfg and
2. replace C47C8D61B4B9 and C47C8D624034 with the mac addresses that you are interested in.
