MQTT Broker Publishing
indi-allsky has the built-in capability to publish data from your all sky camera to an MQTT broker service.
You can find the settings related to the MQTT service in the configuration form.
Included is a script to publish the auto-discovery topics for Home Assistant. The script only requires a few seconds to run and only needs to be run once. Images and other sensors related to your allsky camera will automatically populate on your dashboard.
First, setup the MQTT integration in Home Assistant. After the integration is enabled, run the script below. If you run the script before the integration is setup, no entities will be displayed. Just re-run the script again.
source virtualenv/indi-allsky/bin/activate
./misc/home_assistant_auto_discovery.py
The default base topic is indi-allsky/. This can be overridden in the config section.

Included in the repository is a script that an quickly deploy a Mosquitto MQTT broker to your system.
The script is at ./misc/setup_mosquitto.sh. The script will ask for a password for the indi-allsky mqtt user.
Mosquitto will be setup with the following ports:
| Port | Service |
|---|---|
| 1883 | mqtt no encryption (loopback only) |
| 8883 | mqtt with encryption |
| 8080 | websockets no encryption (loopback only) |
| 8081 | websockets with encryption |
You can use a mqtt client such as MQTT Dash on Android to subscribe to a local mosquitto server and view the data published in real-time.
