To warn, alert, or notify.
mqttwarn - subscribe to MQTT topics and notify pluggable services.
mqttwarn subscribes to any number of MQTT topics and publishes received payloads to one or more notification services after optionally applying sophisticated transformations.
A picture says a thousand words.
Notification service coverage
mqttwarn comes with over 70 notification handler plugins, covering a wide range of notification services and is very open to further contributions. You can enjoy the alphabetical list of plugins on the mqttwarn notifier catalog page.
The mqttwarn documentation is the right place to read all about mqttwarn's features and integrations, and how you can leverage all its framework components for building custom applications. Its service plugins can be inspected on the mqttwarn notifier catalog page.
pip install --upgrade mqttwarn
You can also add support for a specific service plugin:
pip install --upgrade 'mqttwarn[xmpp]'
You can also add support for multiple services, all at once:
pip install --upgrade 'mqttwarn[apprise,asterisk,nsca,desktopnotify,tootpaste,xmpp]'

OCI container image
mqttwarn on a container infrastructure like Docker or
Kubernetes, corresponding images are automatically published to the
GitHub Container Registry (GHCR).
To learn more about this topic, please follow up reading the Using the OCI image with Docker or Podman documentation section.
In order to learn how to configure mqttwarn, please head over to the documentation section about the mqttwarn configuration.
# Run mqttwarn mqttwarn
To supply a different configuration file or log file, optionally use:
# Define configuration file export MQTTWARNINI=/etc/mqttwarn/acme.ini # Define log file export MQTTWARNLOG=/var/log/mqttwarn.log # Run mqttwarn mqttwarn
There are different ways to run mqttwarn as a system daemon. There are examples
for systemd, traditional init, OpenRC, and Supervisor in the
of this repository, for example supervisor.ini (Supervisor) and
In order to directly invoke notification plugins from custom programs, or for debugging them, see Running notification plugins standalone.
For hacking on mqttwarn, please install it in development mode, using a mqttwarn development sandbox installation.
These links will guide you to the source code of mqttwarn and its documentation.
You will need at least the following components:
- Python 3.x or PyPy 3.x.
- An MQTT broker. We recommend Eclipse Mosquitto.
- For invoking specific service plugins, additional Python modules may be required.
