MCZ Musa Python Controller

This program allows controlling remotely your MCZ Musa pellet stove and retrieve its status. MCZ Musa Python Controller uses a MQTT broker to receive JSON commands, convert and send them to the MCZ Musa through a Web Socket connection.

It has been tested on MCZ Musa Suite Comfort Air 12 M1 on a Raspberry Pi Zero W. Basic commands should be compatible with all Maestro powered stoves.

Installation

To run MCZ Musa Python Controller your smart home gateway device connection must be bridged between the stove internal Wi-Fi and your local network. It can be achieved easily with a Raspberry Pi device and, if an Ethernet port is not available, a (Micro) USB-Ethernet adapter.

The first step is installing a MQTT message broker, for example Mosquitto.

sudo apt update
sudo apt install -y mosquitto mosquitto-clients
sudo systemctl enable mosquitto.service

Install, then, python3.7+ dependencies with

sudo apt install python3-pip
pip3 install -r requirements.txt

After connecting to the stove's Wi-Fi, run

python3 musa

Or run sudo bash install.sh

Containerization

An alternative to MCZ Musa Python Controller installation is its docker containerization, with lightweight Alpine images. It requires the installation of docker and docker-compose. For Raspberry PI see Raspberry PI Docker Installation Guide.

After the installation and the connection of your device with the stove's Wi-Fi, simply run the MQTT broker and the Python Controller with

# download eclipse-mosquitto base image
docker pull eclipse-mosquitto
# build the MCZ Musa Python Controller image
docker-compose build
# run the container (detached)
docker-compose up -d

and stop it with

# stop the container
docker-compose down

Examples

To send commands to the stove see:

• examples/publish.py: message pubblication examples;
• musa/src/commands.py: list of all known commands.

To retrieve the stove's infomation, see examples/read.py. See also musa/src/cfg.py for the configuration parameters.

Integration with existing apps

Sending messages: your app should be able to publish messages on /mcz/in MQTT channel.

Receiving results: listen to /mcz/out MQTT channer or eventually, change the musa/src/ws.py function on_message to send Web Socket parsed messages directly to your app.
