# mqtt-notify MQTT to Desktop Notification script, for use with [dm8tbr](https://github.com/dm8tbr)'s [mqtt-notify.pl](https://github.com/dm8tbr/irssi-mqtt-notify) [irssi](https://irssi.org/) script. [![GPLv3 license](https://img.shields.io/badge/License-GPLv3-blue.svg)](http://perso.crans.org/besson/LICENSE.html) ## What `mqtt-notify.pl` sends irssi's notifications to an [MQTT](https://mqtt.org/) broker (such as [mosquitto](https://mosquitto.org/)). `mqtt-notify.py` takes those messages and turns them into [desktop notifications](https://developer.gnome.org/notification-spec/). ## Why If irssi runs in [GNU Screen](https://www.gnu.org/software/screen/) or [tmux](https://github.com/tmux/tmux) on a remote system then translating IRC notifications into desktop notifications is not trivial, but some solutions do exist such as [irssi-over-ssh-notifications](https://github.com/equalsraf/irssi-over-ssh-notifications) (which I used successfully for many years). Most of these solutions require that a remote port is forwarded via `ssh -R` to the client to transmit the notifications—which is fine until you'd like to receive that notification on your phone so you don't miss your team lunch or use [mosh](https://mosh.org/) where port forwarding isn't possible. ## How `mqtt-notify.py` uses * [paho](https://www.eclipse.org/paho/) to access the MQTT broker * [libnotify](https://gitlab.gnome.org/GNOME/libnotify) to make desktop notifications * [libsecret](https://wiki.gnome.org/Projects/Libsecret) to store and retrieve passwords * [dbus-python](https://dbus.freedesktop.org/doc/dbus-python/) and [glib](https://gitlab.gnome.org/GNOME/glib/) to run the main loop and track notification closures ## Setup `mqtt-notify.py` can be run as a [systemd](https://www.freedesktop.org/wiki/Software/systemd/) user service or started manually. Setting up an MQTT broker is left as an exercise to the reader. mosquitto is relatively simple to set up. Ensure that you set up `mqtts://` so that your messages are secure in transit (easily done with [Let's Encrypt](https://letsencrypt.org/)). Various guides are available online. ### Installation ```sh $ mkdir -p ~/bin $ cp mqtt-notify.py ~/bin $ mkdir -p ~/.config/systemd/user/ $ cp mqtt-notify.service ~/.config/systemd/user/ ``` ### Configuration A simple example configuration file is available at `config`. Copy and modify to suit your needs. ```sh $ mkdir -p ~/.config/mqtt-notify/ $ cp config ~/.config/mqtt-notify/ ``` #### Password The user's MQTT authentication password is stored with `libsecret` and will be looked up via the username and the hostname stored in `config`. Add the password to the `libsecret` database. ```sh $ secret-tool store --label="mqtts://example.com" user myuser service mqtt host example.com Password: ********** ``` ### Usage #### As a user service ```sh $ systemctl --user daemon-reload $ systemctl --user enable --now mqtt-notify ``` #### Manual (Assumes that `~/bin` is in your `$PATH`) ```sh $ mqtt-notify.py -c ~/.config/mqtt-notify/config ```
