Implement MQTT Persistence #398

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
To allow MQTT to be used as a persistence strategy, a new 
org.openhab.persistence.mqtt bundle should be implemented.

It should be possible to configure the persistency output to text, CSV, JSON or 
XML.

The topic and message format could be made configurable in the cfg file, e.g.
mqtt-persistence.broker=<brokername>
mqtt-persistence.topic=/v2/feeds/${item}.csv
mqtt-persistence.payload=${state},${timestamp}

Xively could be used as example target for the messages.

I assume we will need a io.transport.mqtt bundle in the openHAB core, so that 
the libary can be shared between the binding and the persistence service, right?

It will definitely need the io.transport.mqtt bundle, which is already 
available in my clone.  If the io.transport.mqtt bundle is included in the core 
distribution, then you should take into consideration that it requires Java 1.7 
to run due to it's dependency on Eclipse Paho.

ok, we agreed on Java 1.7 for the openHAB 1.3 release - so no problem here, but 
thanks for the info!

I've added a new wiki page 
https://code.google.com/p/openhab/wiki/MQTTPersistence
and pushed the org.openhab.persistence.mqtt bundle to my clone.

Assigning to Thomas for review...
