The Koubachi Sensor is a small battery powered device, that measures soil moisture, light intensity and temperature, measurements are then transmitted via W-LAN to a server. Koubachi Sensors were sold until 2015 and the original Koubachi servers retired in October 2019.

This project aims to replace the original Koubachi server with a bridge, that forwards measurements to a custom MQTT or REST end point, such that the Koubachi Sensors can still be operated when the original servers got shut down.

koubachi-pyserver can be run using only dependencies available in Debian buster. Run the following commands to install all the required packages and clone the repository:

sudo apt install git python3 python3-yaml python3-flask python3-paho-mqtt python3-cryptography
git clone https://github.com/koalatux/koubachi-pyserver.git
cd koubachi-pyserver

First read about configuration below, then to launch the server, run the following command:

PYTHONPATH=$PYTHONPATH:src python3 -m koubachi_pyserver.app

Running the koubachi-pyserver requires Python 3.7. On a Raspberry Pi running Raspbian Buster this comes pre-installed but git won't be available by default:

sudo apt install git

koubachi-pyserver can use pipenv for dependency management and virtual environments. Make sure that pip and pipenv are installed. Note: the following does a user installation to prevent breaking any system-wide packages. If pipenv isn't available in your shell after installation, you’ll need to add the user base's binary directory to your PATH:

sudo apt install python3-pip
pip3 install -U pipenv
PATH=$PATH:$HOME/.local/bin

Download the latest release or clone the master branch with Git as shown below. Then, create a virtual environment with pipenv and install all project dependencies:

git clone https://github.com/koalatux/koubachi-pyserver.git
cd koubachi-pyserver
pipenv install

First read about configuration below, then to launch the server, run the following command:

pipenv run python -m koubachi_pyserver.app

Now you need a config.yml that contains the encryption keys and calibration data for your Koubachi Sensors. Write an e-mail to [email protected] and mention the MAC addresses of your Koubachi Sensors. Within a few days someone will reply with the required data.

Configuration is work in progress. Please refer to the issues page if you would like to help contributing.

Read in the API documentation how to reconfigure your Koubachi sensor to connect to your own server.

Install development dependencies:

pipenv install --dev

Perform static type checking:

pipenv run mypy --strict src
