mqttlauncher

Allows precise command execution based on exact MQTT message payloads, enabling fine-grained control over automation triggers as shown in the configuration examples.

Subscribes to multiple topics using wildcard patterns, providing flexible message routing without manual topic enumeration, ideal for dynamic IoT setups.

Automatically publishes command stdout and stderr to derived MQTT topics with /report suffix, facilitating remote monitoring and debugging, as demonstrated in the screenshot.

Supports per-machine configuration via .d subdirectories that merge in lexical order, allowing easy environment-specific adjustments without modifying the main config file.

Uses the @!@ string to substitute payload into command arguments, making commands adaptable to incoming message content, as illustrated in the dev/2 and dev/3 examples.
