sia-server - IoT backend server

Age	Commit message (Collapse)	Author
2 days	Use default config	xengineering
	The default config JSON is embedded as bytes into the executable. Instead of constants the default values are now parsed from these embedded bytes.
2 days	Implement <prefix>/server/health	xengineering
	This indicates if the Sia server is available and connected to the MQTT broker. Using the MQTT Will messages these will also be sent if the Sia server unexpectedly crashes. Using the retained flag it is ensured that freshly connected MQTT clients will receive these messages even when they missed the initial one from the Sia server.
2 days	Add MQTT keepalives	xengineering
	This issues ping request / response messages between the Sia server and the MQTT broker making sure an interrupted connection is noticed.
2 days	Implement MQTT reconnects	xengineering
	This is a central requirement to ensure a restart of the MQTT broker does not harm the Sia server operation.
2 days	Log MQTT disconnect	xengineering
	This makes connection loss visible during debugging.
2 days	Separate MQTT logic	xengineering
	This reduces the coupling between the MQTT-related code and everything else to a single `tx` channel of type `MQTTMessage`. This improves the code quality significantly.
